Multi-Perspective Palm Reading: About Hands & how to make a Hand-Diagnosis

A Hand-Test for recognizing Marfan syndrome!

with 172 comments

In may 2011 a detailed report was presented at this blog about how a ‘multi-perspective’ approach to the hand can be used to find the most essential hand characteristics in Marfan syndrome. Dozens of comments, questions and suggestions were made in response.

Time for a more detailed report:

The brand new ‘Marfan Syndrome Hand Test’ (see above) provides you a unique opportunity to make a first check-up for Marfan syndrome via your own hands!

The most discriminating hand featured typical for Marfan syndrome are included in this test – including: various aspects of arachnodactyly (spider fingers), which manifest via the hand shape; various guidelines for recognizing skin hyperelasticity, which relates to the hand skin quality; and a short list of hand signs for hypermobility, which relates to the hand motorics.

More details about the hand in Marfan syndrome and the background of this test are presented at 

(Your thoughts & observations are welcome!)

    • Thanks for putting this post up. I’m 13 and I’m 5 ft 11inches- which is pretty tall😀 I could do everything in this hand test and got all the points so my mum took me to see a consultant and I am now taking some tests so they can decide if it’s Marfan. Again thanks for putting up this post.

      • Hello Coolkid123,

        Thanks for your feedback so far + I would welcome you to report the outcome of tests.

        Take care + best wishes!


        July 7, 2015 at 10:55 pm

      • So, I got A, C, D, and H, and I’m 14. Should I go in for testing?


        May 3, 2017 at 1:02 am

      • Hello Tallguy47,

        Due to your age I think it would not be appropriate to go for testing based on just these 4 hand signs (17 points, only 1 point short for qualifying for the hand test).
        However, at your age you probably a medical test ahead in the next few years – you might then want to share your concerns regarding Marfan if appropriate.

        I hope this answering eases your mind a bit?


        May 17, 2017 at 12:13 pm

    • I am pretty tall for my age and very flexible so I was tested for this last year and I could do almost all of it but my doctor decided against further testing, so I went on with life, a year later I see this test online and try to give it a go and score a 22 (im 13 years old) Should I go back to my doctor?


      November 13, 2020 at 11:45 pm

  2. I have just added some improvements to the test, including a reference how to discriminate Marfan syndrome from e.g. Ehler-Danos syndrome (which used to be know as Marfan syndrome type 2) and Loeys-Dietz syndrome.


    June 8, 2012 at 2:04 pm

  3. The Marfan Syndrome Hand Test appears to work pretty well.

    The test has now been validated: 14 out of 17 Marfan people past the test so far.

    (The other 3 Marfan people had scores in the ‘borderline’ category, which relates to a score varying from 9 to 16 points)

    PS. Only one ‘false postive score’ reported so far (this concerned a person who has Loeys-Dietz syndrome type 2b – which was known untill 2006 as Marfan syndrome type 2).


    June 29, 2012 at 6:10 pm

  4. I scored a 12. I have a and d. Should I seek medical advice? I am also nearsighted, I have lower back problems, high arch in mouth. I’m not flexible though and can’t do the first hand sign


    September 8, 2012 at 4:08 am

  5. Hi Nicole,

    Thank you for your question!

    The combination a and d only indicate that you have a rather slender constitution, but that is not a typical combination for Marfan syndrome (because too many other typical characteristics appear to be missing).

    So, based on the details that you have reported so far… I think you have not much to worry about regarding Marfan syndrome (nor the other associated syndromes that I mentioned in the article).

    I hope this eases your mind (on top of the fact that you did not pass the test!)



    September 8, 2012 at 6:37 pm

  6. I think I have positive results in b, c and d (16 points).

    I don’t have Marfan diagnosticated, but I have Pectus excavatum… I wonder if I could have a light version…


    September 13, 2012 at 12:18 am

  7. My daughter’s doctor said she might have mild Marfans. I did this test on her and she didnt get any points. She is tall for her age, but we come from a tall German backround. She is not flexible or stretchy skin. She has a high arch and crooked teeth, but she sucked her thumb until the age of 3. Should I be concerned, this doctor has me tripping!


    September 13, 2012 at 5:05 pm

  8. I have stressed myself over this for years. I am a 22 year old male 5’8. My mother is 5’6 and my father is 5’7-5’8. i did pass (d) and (g). My wingspan is about 1/2 inch longer than my height, so i dont know if that is a positive test for (b). Should i go see a doctor. i would really appreciate it if you could answer. Thanks.


    January 1, 2013 at 6:00 am

  9. Hello S.

    You only qualify for d and g (not for b, and probably for a neither).
    This implicates that you probably do not have Marfan syndrome.

    Now, if you are still in doubt… you might want to contact your general practitioner in order to check out if you d+g combi could relate to something else

    Thank you for asking! 🙂


    January 5, 2013 at 11:27 pm

  10. I scored a C & D. Now you said that’s 90% of marfan syndrome ,but a lot of other people in my school could do it.


    February 26, 2013 at 2:51 am

    • Hello Jason,

      Sorry, your report is unlikely correct.
      You must have misunderstood a few details of the guidelines.

      – Regarding C: it requires to put the thumb inside the palm (not at a the level of the fingers);
      – Regarding D: the thumb + pinky (no other fingers allowed to get involved!) are required to do the gesture around the wrist.

      You are welcome to specify your report, but the point system clearly shows that C + D can only make about half of the points that are required to make a hand-diagnosis for Marfan syndrome.

      So, it is obvious that something went wrong in your process of the info; you can find more detailed guidelines here:

      Anyway, thank you for you efforts & comment!


      PS. Your reference to 90% probably results from the indicative value of features C & D in Marfan syndrome; C and D are each present in more than 90% of cases in Marfan syndrome… but you should not perceive those percentages like they represent 90% of all it takes to find Marfan syndrome – they represent only one of the key-elements to find a ‘positive’ case!


      February 26, 2013 at 3:25 pm

  11. My English isn’t that great, thats why I have huge issues with the hand thumbs-sign C. I am 176 cm tall and pretty skinny with 56 kg (used to have 64 kg last year tho).

    So to my question ..

    I can force the C hand sign with no big problem, but is that how it mean to be? If I just put my thumb into the palm, I don’t have the sign. I really don’t understand that. 😀

    A doctor of mine mentioned the Marfan-Syndrome so I googled it. Now I am really, really confused. My heart and my eyes have no issues at all (both checked due to a Myokarditis I had), but I can do Hand Sign D without any problem. C I can do aswell, but I need to force it. If I make a casual fist my thumb is not outside the hand.

    I hope you can explain me the C sign in simple English, so I hopefully understand it.


    March 14, 2013 at 12:44 pm

    • Hello DannyD,

      Don’t worry, your English language is just fine!

      Regarding thumb sign C, you should be able to do this sign easily, so you probably pushed it a little too had. A body height of 176 cm doesn’t sound like Marfan syndrome – unless when your length exceeds the body height of your family members significantly!

      (Low body-mass index is often normal in Marfan syndrome, so your body mass index of 18 should not be recognized as significant for Marfan either)

      So, I think you only have sign C… which implicates that your chance for having Marfan is probably (very) small – because most skinny people do not have Marfan syndrome.

      Thank you for asking! 🙂


      March 15, 2013 at 3:19 am

  12. I just came across this site. I’m shorter than most people in my family (5’2”) but I got B, D (only on one wrist) and G-J. Would you say that my chances of Marfan are pretty high? I’m planning to see a doctor about this soon.


    April 30, 2013 at 9:51 pm

  13. Hi I am from India ,My height is 177 cm whereas my father is 163 cm and my mother is 154 cm tall .
    I have the ‘d’ and a little bit of ‘c’ .I am skinny .I am 17 and my BMI is 17th percentile . Do I have the Marfan Syndrome ? Please help.


    June 15, 2013 at 7:30 am

    • Hello Anand,

      Your description suggests that you might score only 4 to 8 points (for characteristic d, possibly combined with c), which indicates that you probably do not have Marfan syndrome.

      By the way, BMI is not a key-feature in Marfan syndrome; because low body weight is usually not related to Marfan syndrome.

      If you hand length is below 11% of your body height then you probably do not have Marfan syndrome.

      I hope this is helpful?



      June 15, 2013 at 7:10 pm

  14. Hi! Can you explain how to measure A? Where exactly starts the hand? My arm span ratio to body is 1.05, i can do C, D, G, H. I also have pretty severe pectus excavatum and some joint hypermobility. No heart involvement according to tests. My GP suspects Marfan syndrome/EDS but commercial genetic testing is not available in my country. Any ideas/tips?


    June 24, 2013 at 10:44 pm

  15. Hello Deecoy,

    Thank you for your interesting questions!

    Regarding a, you can measure ‘hand length’ from the distal wrist crease to the tip of your middle finger (average for both hands); then calculate the ratio to your body height.

    If your assessments are correct, you score at least 10 points… up to at least 18 points if we consider that your at the borderline of scoring 8 points for b,

    Combined with your severe ‘pectus excavatum’… I think your chance for passing a genetic testing for Marfan syndrome is far above 50% (and I am sure that your will very likely pass other alternative-tests for Marfan syndrome as well).

    If you also qualify for a, that would implicate that according the hand test for Marfan syndrome your score is likely in the borderline category ‘typical for Marfan syndrome’.

    I hope this is helpful?

    Greetings from The Netherlands!


    June 25, 2013 at 2:19 am

  16. Thanks. That is very helpful indeed. Ill get back to share the results with you when i have measured my hands.


    June 25, 2013 at 9:56 am

  17. I scored about 11,2 % on test A so i guess my total score is 10-20 points depending on interpretation. I can also do sign I on my left hand. My right hand is a little stiffer though.


    June 29, 2013 at 11:19 pm

  18. Deecoy, how about your body height? If your body height is higher than your family members (assuming that they don’t have Marfan syndrome), that would provide another clue that you are not far away for scoring for point.

    (If your body height is not taller than your family members’ body height than you would for sure not score any points for point a)


    June 30, 2013 at 5:59 pm

  19. Im the talest one in close family (mother, father, siblings) Im almost 180 cm, my dad is second with about 175 cm. None of them have marfanoid habitus. To get a genetic testing done via public health care, the indications for the disease must be VERY strong. I guess ill have to convince my GP to refer me to a geneticist.


    July 1, 2013 at 12:41 am

  20. Okay, since you are the tallest in your (close) family you are not far away from scoring points for point a; I think the implicates that according this test your hands are at the borderline between ‘very likely Marfan’ and ‘typically Marfan’.

    My estimate is that you have a 90% chance of having Marfan syndrome. So I would like to advice you to try to find out if you have even more body features (beyond the hand) that are typical for Mafan syndrome.

    If you are able to find more features that you are not yet aware of (and IF your assessments so far are correct!), then I think you have a strong case to make a request for genetic testing.

    Wishing you good luck & you are welcome to let me know the outcome of this assessment-proces.


    July 1, 2013 at 11:20 am

  21. Hi,

    I have c, d, e, and i. That amounts to 11 points. What does this mean? I’m a “borderline” case? Should I get tested? I also have severe pectus excavatum.


    September 25, 2013 at 1:48 am

  22. Oh, I forgot, I have scoliosis as well.


    September 25, 2013 at 1:50 am

  23. Hello Wondering,

    First of all, thank you for your question.

    Your combination (including the pectus excavatum + scoliosis) sounds rather typical for Marfan syndrome, so assuming that you hand assessment is correct I think you have a considerable chance for having Marfan.

    By the way, what is you age?

    I should also add here that the combination of pectus excavatum + scoliosis is also commonly seen in Loeys-Dietz syndrome (which was previously known as ‘Marfan syndrome type 2’).

    I hope this info is helpful?


    PS. Recently I was confronted with the unusual case of a Marfan person who scored 0 points for the hand test, but she mentioned to be aware that she has an atypical morphological variant of Marfan syndrome.


    September 25, 2013 at 12:16 pm

  24. hi, i am marco, i’m 29 and i am 179 cm tall (my father 172 cm, my brother 186 cm)
    no marfan cases in my family
    have a slight aortic ecstasia which i’m monitoring once a year and in the last 10 years remained constant.
    in this test i have scored 7 points (D+G+H+I) therefore <5%.
    i have also gone through the "advanced hand tests" and i am negative to all the points.
    i have no pectum excavatum, no flat feet, no eyes problems, i have never experienced any dislocations in my life.
    do i have marfan? 😦


    October 10, 2013 at 9:37 am

  25. i forgot to say: i have no scoliosis. also, my father used to be very slim at my age as well.


    October 10, 2013 at 9:47 am

  26. another detail: my hands length is 17,9 cm


    October 10, 2013 at 12:07 pm

  27. Hi Marco,

    First of all, thank you for your question (+ the various details)!

    At first sight I think the details that you have shared indicate that you only have a relatively small chance for having Marfan syndrome… but your heart problem could be the essential clue here.

    However, since you are aware (+ in control) of your heart problem there is likely no urge for you to start a formal diagnosis for Marfan syndrome, but since you score points one 3 dimensions of the hand (+ combined with your heart problem) there is a small chance that you do have Marfan.

    I should add here that the relatively long body height of your brother is a contra-indicator for you regarding Marfan syndrome.

    How about your facial characteristics? Maybe you can try to figure out if you have any facial characteristcs that are typical for Marfan… if those are missing as well then your chances for having Marfan are likely very small.

    I hope this is helpful?



    October 10, 2013 at 1:14 pm

  28. thank you very much for your comment.
    here is a picture of my face (i’m the one on the left, on the right there’s my brother)

    also what do you mean by contra-indicator?

    regards and thanks


    October 10, 2013 at 1:42 pm

  29. (just for your info, although height looks the same, the floor was not regular and he was without shoes while i was wearing heeled ceremony shoes) 🙂


    October 10, 2013 at 1:46 pm

  30. i am so sorry for being annoying but the possibility of having Marfan is really struggling me this months, with impacts on my normal life (anxious states, etc.)


    October 10, 2013 at 1:53 pm

  31. My nephew is 13 and is 5’8” tall and weighs 98 lbs. He has mild pectus carinatum and a positive wrist and thumb sign. His arm span is 1.03. (His father has an arm span of 1.06, but definitely does not have Marfan’s). He is not flexible and he does not have scoliosis. Do you think he can have Marfan’s? Thank you.


    November 10, 2013 at 5:34 am

    • Hello Chris,

      Yes, this could be a typical combination of features seen in Marfan syndrome (e.g. his weight appears to be <2nd percentile for his age) – though your feedback does indicate that he is likely to pass the Marfan hand test.

      This could provide another clue: how about his 'hand length to body height' ratio???

      (If his ratio is close to 11.5% then he could be a borderline case regarding point a of the hand test)

      Greetings from The Netherlands!


      November 10, 2013 at 11:15 pm

      • Thank you so much for your quick response. His hand length to body height is 11.3%, so I guess it’s borderline…


        November 11, 2013 at 12:12 am

  32. Yes Chris, we could describe 11.3% as borderline… which implicates borderline for point a and point b in the hand test; I think this is an indication to proceed and check out whether your nephew displays more clues – especially if has concerns regarding his health/fitness condition (I know this is rather unspecific, but due to his age you might also consider the option to wait and see how his body features develop while getting old… because young people have a slightly higher chance to display features).

    I hope this is helpful?


    November 11, 2013 at 1:55 am

    • Thank you very much for all your information. My nephew is in perfect health otherwise and does not display any Marfanoid facial features. Hopefully, he is just a lanky teen going through an awkward stage, but he has an appointment to see a geneticist soon. By the way, his father has an arm to height ratio of 1.06, and his mother has a positive thumb sign. Hopefully it is not Marfan, but rather he just inherited his dad’s long arms and his mother’s long thumb.


      November 11, 2013 at 2:59 am

  33. Hello Marco,

    Sorry for this rather late response. Thank you for sharing the photo; don’t worry, you do not have any of the 5 typical facial characteristics. I hope this will help you a little bit to deal with your worries/disstress?

    PS. The contraindicator represents a factor that raises your chance that you do not have Marfan syndrome.


    November 11, 2013 at 2:01 am

    • Thank you very much Martin, it’s a lot better now. I’ve been to the Marfan center in Milan.
      they told me it’s not even necessary to do the genetical tests, i do not have Marfan (i scored 2 points). I just have to keep monitoring the aortic root diameter once a year. In the last 4 years the value has always been the same (40 mm), so it’s a good sign. thanks again Marco


      November 11, 2013 at 9:12 am

      • Ah, sounds great Marco; very nice to hear that the experts in Milan were able to confirm that you do not have Marfan syndrome.

        Thank you for sharing this!



        November 15, 2013 at 12:57 pm

  34. Hallo there! Thank you for the hand test! It is a very useful self-diagnosis tool.

    Can you please perhaps advise me whether I should consider seeing a doctor about possible marfan syndrome?

    In the test I scored on the following:

    B (possibly…my wingspan ratio is 1.044, just shy of the 1.05 cutoff)

    E,G,H and I

    giving me a score of 13 or 5 depending on how you interpret my wingspan

    Other considerations for possible marfans in me is…

    I have keratoconus ( a degenerative disease of the cornea causing extreme astigmatism, nearsightedness and the thinning/weakening of the cornea)

    I have hypermobile joints, with a tendency for my knees to dislocate.

    I have extremely slight scoliosis, indicated only by my right hand hanging a little lower than my left hand.

    I have some stretch marks on my hip-areas, but these appeared during my growth spurt during puberty and I haven’t gotten any new stretch marks since.

    My hands and nails have normal dimensions.

    I dont have any of the additional 8 minor hand signs for marfan (except a slightly curved fith finger, which can be explained by my piano-playing , which involves me playing on the outside of the pinky, ultimately bending it towards the rest of the hand over the years)

    I don’t have flat feet or even low foot-arches.

    My face doesn’t look marfanoid in the slightest.

    My breastbone is normal.

    I don’t know how healthy my heart or aorta is, because I’ve never had them examined.

    I am 26 years old, male, 1.82m tall (wingspan 1.9m, when I REALLY stretch my arms), weigh 85kg and have a medium-sized frame (according to my wrist circumference).

    Any comments/advice please?

    Thank you in advance!


    November 15, 2013 at 11:48 am

    • Hello Boertjie,

      Since both keratoconus & scoliosis are associated with Marfan syndrome, I think your score of 5 or 13 is likely more significant than how it may appear at first sight.

      Your pinky report sounds like you have ‘clinodactyly’ or ‘camptodactyly’; this feature is also listed in the additional hand-sign list for Marfan syndrome, see just below halfway in this article:

      I would recommend for you to search for more clues, because your constelation of features appears to include many clues that are associated with Marfan!

      I hope this suggestion is helpful?

      (Please, feel free to share more details)


      November 15, 2013 at 1:24 pm

      • Hello Martijn

        Thank you for your response!

        I’m not completely sure if my scoliosis might be an indicator in this case, because it is only a very slight degree of scoliosis. The most visible sign of it is that my right hand hangs a little lower at my side than my left hand – perhaps about 2cm lower. And if you look REALLY closely, you can see my right shoulder is a little lower than the left.

        As for my pinkies…it is not camptodactyly because all of the joints move freely. It might be clinodactyly. But again, in a very slight degree…barely noticable.

        Additional details I can think of that might indicate/contra-indicate marfan are:

        My feet have absolutely no marfan-like appearance. They are rather broad and the toes almost seem a little short.

        I still have my wisdom teeth and never had any trouble with them. I guess the fact that my jaw grew enough to accomodate my wisdom teeth may correllate with my limbs that grew longer than avarage.

        My finger- and toenails tend to be a little soft and easy to tear (weak connective tissue?). My fingernail length/width ratio avarage is 1.29. I measured the width at the widest part, which was near the fingertips.

        My keratoconus is severe. Also…years after corneal transplants, it re-appeared in full severity in one eye, and seems to be slowly developing in the other eye as well.

        There are quite a few clues pointing to hypermobile and somewhat unstable joints.

        And finally, I believe I do have a somewhat marfanoid overall-appearance. See this photo of me…

        (sorry for the poor quality, but I had only my webcam available at the time…)

        I can’t really think of anything else out of the ordinary.

        Thinking all of this through, I guess that regardless of whether I have marfan syndrome or not, it is clear that I have weak connective tissue and need to get my heart and aorta examined on a regular basis.

        And thank you for your welcoming attitude. I appreciate it!


        November 15, 2013 at 10:23 pm

  35. Hi
    I am 26 years old male. I scored b, c (almost), d, e, h, i and j. Also, I have flat feet (pes planus). I am 1.72m tall and 64kg max weight.
    I have Gorlin sign and Reverse-Namaskar sign.
    I have square stooped shoulders.
    I have high palate
    Fatigue, lack of consentration, Postural orthostatic tachycardia syndrome (sometimes)
    Any advice please? (sorry for my English)

    Thank you!


    January 15, 2014 at 9:07 pm

    • Hello,sohaib!

      I’m my no means an expert and I’m also just a guest to this blog, but it seems very possible that you have Marfan Syndrome or some connective tissue disorder. I think you should have your heart and aorta examined.

      As for fatigue and lack of concentration, there is quite a lot that might help…
      1) make sure you get enough sleep
      2) regular mild exercise…but you must consult a doctor about what exercise would be suitable for you.
      3) make sure you get enough B-vitamins, magnesium and Omega 3 and 6 fatty acids via your diet or supplements. Never underestimate the value of a well-nourished nervous system!


      January 17, 2014 at 9:20 pm

    • Hello Sohaib,

      Your 15 point score, combined with your borderline score for feature c + the combination of the gorlin sign & reverse-namaskar sign raises the likely possibility that you have Marfan syndrome.

      Have you noticed the additional advanced considerations for a more detailed assessment for the hand in Marfan syndrome?

      (See the list of 8 other hand features presented inside the paragraph: ‘The hand in Marfan syndrome:
      8 other Marfan hand signs!: )

      Please feel free to ask for more details if necessary.

      Kind regards from The Netherlands!


      January 21, 2014 at 3:24 am

  36. Thank you for answering all of the concerns on this page and for the diagnostic chart. Here is my question. If a person is still in puberty when hands and feet tend to grow before height, could that cause a false + for parts A and B? My daughter is 11 and is 5ft 4inches, very long limbs and fingers with flat feet and is borderline for A and B. No scoliosis, eye problems. No other points on the test including the wrist and thumb test. thank you for your thoughts!


    January 20, 2014 at 9:59 pm

    • Hello Alicia,

      Great question!

      In general I think that hands & feet do not grow much before height, so I think the odds are not very high that the ratios will change much while she is getting older.

      5ft4inches is indeed quite high at age 11, but at age 12 this height would definitely be within the normal range; so it might be relevant here to know how many months your daughter has passed age 11; though I should add here that it is probably more importante to judge this in the perspective of the family members (if you and/or the father have tall body height this could also indicate your daughter’s body height is within the normal range – even though it is considerably high for her age).

      So, even if your daughter would score 16 points for feature A & B this would implicate that she is still 2 points away from passing the hand test for Marfan syndrome (as the criterium of 18 points appears most appropriate for here age).

      Does this help you decide whether she actually scores any points for A and/or B?

      Greetings from The Netherlands!

      PS. Living in one of the tallest countries around the world I think your daughter’s body height would probably not be recognized as unusual for her age! (Growth charts indicate that she might grow more than 18 cm on top of her current height, so I think her adult height could reach close to 180 – which would be just fine in the Netherlands… many males will likely exceed her height, etc.).

      • You are an angel to be answering everyone’s questions so quickly. She is only 11 and 4 months but her father is 6’2 and she closely resembles him. Thank you for your nice thoughts. I am going to mention it to her Dr. and watch for scoliosis, eye issues and other traits. Keep up the great work with your site.


        January 21, 2014 at 3:23 am

  37. Alicia, thank you for your very generous words + thank you for sharing your appreciation.

    Wishing you & your daughter good luck from The Netherlands!

  38. Hello,

    I have a question about the “c” sign and generally about my situation.
    I know a lot of people who can force the position “C” without any problem (me too). So I think we are doing it wrong. If I put my thumb in my palm it doesnt look outside the palm (misses like 1 cm or so), but obviously I could force it to look like “c” very easily. So how do you actually do it right?

    Other than that, I have striae on my back and my butt, this prolly comes from a good growth at the age of 14 through. I havent gain any new since then. I also have slight scoliosis which prolly comes from a accident I had as a young child. Hard to tell here aswell.

    My hand span compared to my body is around 11 %. If you know the elementary shape hands I am clearly a water elemantal hand. My fingers arent even that long with 8,5 cm. Its just the lengh of my palm that makes them look long (11 cm long and only 7,8 breadth)

    My Arm Span is 1.025.

    What really bothers me tho is the size of my wrist. It’s only 14,5 cm. I can EASILY do the “d” sign. I can even get a bit higher than in the picture.

    Other than that. I am 177 cm, 21 years old and I have 70 kg. A cardiologist mentioned I might have “Marfan” as I have a somewhat marfan habitus. A gentest was made, but it was negative (2 gens tested, FBN1 TGFBR2).

    To be fair, my cardiologist had almost no clue about Marfan, he just mentioned that my handshape is kinda “weird” (lol). Now I am in somewhat of a dilemma, as I dont know if I should go to a marfan ambulanz and make a clinical check by marfan spezialist or just let it be. On the score I would hit a 4, with close calls in “a”, “b” and “c”.

    I would really look forward to a response per the e-mail I mentioned. This keeps bothering me since more than over a year. Sorry for my rather bad English, I am from Austria and I havent used my English in a while. 😛


    February 20, 2014 at 5:51 pm

  39. Oh, I was actually wrong. My hand size compared to my body is even 11,8 %. Like I said, I have a large slim palm.

    In my family I am somewhat average in size tho. My Mother is 161 cm, my father (and brother) are both 173 cm. I am only slightly above that. Also my Grandfather and my uncle are both 181 cm.


    February 20, 2014 at 8:19 pm

  40. Hi Dan,

    Thank you for your excellent question regarding the ‘c’ sign; I can only recommend it to make that gesture without using extra force (e.g. from the other hand). So, you would only quality for for this feature if you can do that gesture with just one hand only (slight extra force is ok if it comes all from this hand only).

    Now, I assume that you were able to do the ‘d’ sign with thumb & pinky finger… and your 2nd comment indicates that you do qualify for the ‘a’ sign (the exact number is not high in the perspective of the general population, but the essence is that it requires to be high in the perspective of your close family members… your body height appears more than +2% above the others… even though some more distant family members have higher body height (sorry, it’s hard for me to judge whether this should be perceived as a contra-factor). To me, at first sight I am inclined to say that you do qualify for both aspects of sign ‘a’.

    That would make 12 points (sign d + a), and your scoliosis + ‘marfan habitus’ + striae… together make a very typical constellation for Marfan syndrome.

    Dan, have you tried the list of extra hand characteristics for Marfan syndrome (8 hand characteristics) and Ehler-Danlos syndrome (4 hand characteristics + 1 foot characteristic) ? (See: )

    I hope this is helpful to make up your mind; anyway, thanks for sharing your question!



    February 20, 2014 at 8:56 pm

  41. Hi,

    I’m 15 and had mild pectus excavatum my whole life, but only recently did i find out about Marfan syndrome online, I used to have flat feet (corrected by insoles) I’m 5″8 at the moment at 125 pounds (fathers 6″0 and mother 5″8) I was positive for the ‘D’ sign and ‘G’ but still feel worried about having this syndrome.

    I also have short sightedness although so do both of my parents.
    I had braces when younger.

    What do you think about having it?


    March 4, 2014 at 7:55 pm

    • Hi Jack,

      Scoring 5 points on the Marfan hand test is not a strong clue for Marfan syndrome; however, combined with the combination of ‘mild pectus excavatum’ + ‘short sightedness’ + ‘flat feet’ your score becomes much more significant.

      By the way, your body-mass index is within the range of normal.

      Hmmm… I am not sure at all, but to me it appears that your combination does fall within the range that is typical for Marfan syndrome; maybe you can check out yourself I you also have some of the additional 8 hand signs for Marfan syndrome (listed at about 3/4 of this page):

      Let me know if you need assistance for further assessment!

      Best wishes!!!


      April 8, 2014 at 2:18 am

      • Thank you for your reply:) I don’t appear to have any of the extra hand signs, my hands are quite small to be honest. But yes, It was the pectus excavatum that made me find out about Marfan syndrome in the first place and it’s worried me since!



        April 8, 2014 at 6:55 pm

  42. Hi Martin

    I’m 17. 5″ 8′. Flat Feet (Both Parents Have it). My armspan is 6′. I weight 158lb because I work out quite a lot. In test c my thumb reaches the edge of my hand and in test d my pinky and thumb just touch. My father is 5 feet 6 and my mom is much shorter. On top of that, I think I have very mild pectus excavatum. I have long hands and long fingers but I couldn’t do any of the hand motorics.

    I am very worried.

    Thanks for your help!


    March 12, 2014 at 5:19 pm

    • Hello Kit,

      I think you are close to pass the Marfan syndrome hand test: 16 points so far,.. but you might also score a few bonus-points for feature a???

      Maybe you can also give a measurement for your full ‘hand length’ – measured from the tip of your middle finger to the distal wrist crease…?

      Your body-mass index and your body height appear normal.

      Anyway, thanks for the sharing so far!

      Greetings from The Netherlands, Martijn.


      April 8, 2014 at 2:05 am

  43. Hi Martin,

    Thank you for your comments we really appreciate your help.

    I am 175 cm tall and 50 kg my family also are thin.

    we are all thin and skinny. My younger brother is taller than I am.

    I can do C and D.

    I had pneumothorax in the bast.

    no flat feet

    heart is fine and I did an eco and ECG.

    my arm span is not longer than my hight.

    my upper part is not longer than legs!!

    chest seems normal to me.

    Do I have marfan?!!

    Thank you for reading my comment.



    April 6, 2014 at 10:04 pm

    • Hello yaya,

      Even though you do not pass the Marfan syndrome hand test, your score of 8 points becomes more significant combined with your very low body-mass index & the pneumothorax.condition.

      However, it’s hard for me the judge the significance of this combination since people with your body-mass index obviously have a high chance to score points for hand sign ‘d’.

      I hope this is helpful?

      PS. Very good to hear that your heart is fine!


      April 8, 2014 at 2:27 am

  44. I scored a 22. The ones I missed were h, j, & a, (I missed a only because I don’t really know… if any of my family does have it [suspecting my dad does], then they don’t know it yet.)

    Artemis Trastad

    May 6, 2014 at 8:31 pm

    • I’m half asian by the way, so I’m about the average caucasian height. But I am taller than my mother… If this helps any..

      Artemis Trastad

      May 6, 2014 at 8:32 pm

      • Wait, I didn’t read the bottom part.. I actually did get H, because it goes to 90 degrees

        Artemis Trastad

        May 6, 2014 at 9:55 pm

  45. Hello. I’m back, and I finally measured my arm span to height ratio. It’s 1.031. My arm span is 2 inches taller than my height. I’ve passed test c, g, h, i, and j. (J with slight difficulty, but I can do it. I’m quite flexible.) I’m not sure about a, I don’t quite understand what it’s saying. My mom is 5,1″, I’m 5’5″. Do you think I have Marfan’s, possibly just a mild case? If you haven’t seen my last comments, I am an average height, but this might just be because I’m half Asian. I scored a 16 on this test.

    Artemis Trastad

    May 21, 2014 at 8:38 pm

    • In my previous comments, I was confused with the scoring. I actually got a 16 and I don’t know about a still

      Artemis Trastad

      May 21, 2014 at 8:41 pm

  46. Hello Artemis Trastad,

    First of all, sorry for this late response.

    If I have understood you input correctly then I think you score only 8 points (= c+g+h+I+J); because your arm span ratio (1.031) is not high enough to score any points for b, and regarding point a it appears to me that you are not taller than your father… though you didn’t mention his body height but from the fact that you are just much taller than you mother this does not represent any significant clue at all.

    But maybe I have misunderstood your feedback? If so, you are welcome to explain how you arrived at 16 points.

    Greetings from The Netherlands!


    May 22, 2014 at 1:38 pm

  47. Ahhh! Darn it!
    I have a score of 28! The only things I don’t have are the stretchy skin ones!
    I have joint problems that are just silly! My physio told me to go ask my family Dr. about this. As my knee dislocates, has torn 3 ligaments. They don’t even hurt when they ‘dissolve’. My hip has torn cartridge, which hurts for every movement all day except at the gym for the leg-press machine. I have diastase recti from pregnancy 2 years latter. And last week my rotator cuff tore for no apparent reason. Not to mention the hyper mobile rib I have since I coughed it out of joint when I had pneumonia a few years ago.
    I grew up on a farm and was laughed at every time I dislocated a thumb, twisted an ankle or was exausted at what everyone else was just getting winded at.
    I’m only 5 foot 5. But my mother’s side is tiny little 5 foot and under slight Irish builds. Where as my dad was 6 inches to a foot taller then his other 4 brothers. And his mom can still palm a basketball at 85!
    I am so brining this to my family
    Dr. maybe something can be done to stop the next joint from
    Falling out! I’m pretty sure the only thing that caused the rotato cuff to tear was
    My thinking about reading a heavy book to hard!


    June 17, 2014 at 5:48 am

  48. My daughter scored a 26 (assuming her birth grandfather had MFS). I am making an appointment with her pediatrician now. We are unsure of father’s side medical history because he is adopted but his father was 6’4″, skinny as a rail and died of a heart attack at age 42. I am ordering a copy of his death certificate to see if MFS appears anywhere…

    Sara G.

    June 18, 2014 at 7:13 pm

    • She also has the flat feet and a crowded upper palette. Her eyesight is so far, excellent. Her favorite band (&) has a lead singer with MFS which prompted her to research it. She found the pictures of her “spider hands” which prompted me to look into it. Biggest concern is obviously the risk of heart problems.

      I always thought she would grow into her unusually long arms and legs but I am realizing she is just really is unique! She has friends who spend their time trying to look like one another or try to emulate a certain style. My daughter is my daughter and she alone looks like her.

      Sara G.

      June 18, 2014 at 7:21 pm

      • Hi Sara,

        A Marfan diagnosis is a complex matter, and the techniques might not have been available at the time of your daughter’s grandfather. Anyway, thank you for the sharing!

        Greetings from The Netherlands!


        August 2, 2014 at 4:43 pm

  49. My son scored 27 on this test. I did the test after a physio asked if he had Marfans (He’d dislocated his knee). He also has stretch marks on his torso and has fainted a couple of times. All of which we put down to other things. Can he still be Marfans if he is only 5’10? (at 16). My husband is 6’3′ but my family is all short – 5’3″.


    June 20, 2014 at 11:19 am

    • Hello Ishy,

      Even though many Marfan people grow to above average height, average height should not be perceived as a contra-indication. Therefore the answer to your question is yes, it is not uncommon to see ordinary height in people who have Marfan syndrome.

      I hope this is helpful?


      August 2, 2014 at 4:34 pm

  50. My hands are 7in my height is 61 in but I am the same height as my family.My arm span is 66 inches. I can do C, D, G and I. This is naturally a little concerning. Thoughts? Should I see a doctor?

    Emma Harris

    August 1, 2014 at 9:17 pm

    • Hi Emma,

      Sounds like you score 18 points, and thus you pass this hand test.

      Maybe you would like to take a look at this official checklist for Marfan syndrome named the ‘systemic score’:

      Just let me know it you need any further assistance!


      August 2, 2014 at 1:32 am

  51. I have everything but A (my hand was only 10.5%), C (I only have it in one hand), and F. My geneticist said I have marfanoid characteristics though and is testing me for Marfans, Loey-Dietz, and Ehlers-Danlos so the hand test seems pretty accurate for me. I’m not tall though, only 5’4″ so I’m not sure if I truly do have Marfans.


    September 20, 2014 at 8:00 pm

  52. I was wondering, does the wrist test need an overlap or just contact to be a positive?

    Glynn King

    December 30, 2014 at 4:45 am

    • Hi Glynn King,

      A clear overlap is required, so contact is not enough to score points for the Walker-Murdoch sign (= hand sign 4 in the hand test for Marfan syndrome).

      Thank you for asking!


      December 30, 2014 at 12:04 pm

  53. Hello there! Thank you for this useful screening test!

    I do not pass your hand test (scoring only 3 points – g, h and i).

    However I do have a question about body-proportions… although my armspan/height ratio is only 1.03, my upper/lower segment ratio is 0.85 (I am a white male). My limbs are therefore quite long, giving me a somewhat marfanoid appearance. Do you think my upper/lower segment ratio may be a significant clue when considering the possibility of me having marfans?

    Some of my other features may raise suspicion…

    – severe keratoconus (recurring in one eye several years after a corneal transplant)
    – moderate hypermobility in all my joints
    – long neck
    – high forehead
    – I am tall (1.84m 6ft)

    Thank you for all your patience in answering everyone’s questions!
    Kind regards


    January 31, 2015 at 9:35 am

    • Hello Askie,

      I do not have much experience regarding the evaluation of other body parts, but keratoconus has been recognized to represent a localized manifestation of a mild connective tissue disorder (just like your ‘moderate hypermobility’).
      Additionally, your 3 points hand test score appears the direct result of your ‘moderate hypermobility’, therefore both should best be evaluated to represent just a single factor.

      Therefore I think the result of your hand test indicates that your very likely do not have Marfan syndrome.

      Is this helpful?


      January 31, 2015 at 1:28 pm

      • Yes, your reply is helpful. It makes sense that my array of features point to mildly weak connective tissue, but not necessarily something as severe as Marfan Syndrome. Next time I’m at the doctor I’ll just mention these things to him.

        Thank you for your reply! 🙂


        January 31, 2015 at 3:27 pm

  54. Hi there, I went to a movement therapist and she says I should be checked for Marfan or any similar disease. I have a “gothic palate”, crowded teeth only in the lower jaw, I am not very tall, but very skinny. I have long fingers and toes but I still dont pass “a” and “b”. My legs are actually shorter than average. I had severe scoliosis as a teenager but corrected most of it with special exercises, now it is moderate. I am not sure about evaluating the hand signs – I have the wrist sign (d) . I can do the thumb sign but I really have to force it (to the point it hurts). I have “g” and “h” but nothing else. I am short sighted but not much (I also have a lazy eye), I have a long face (but again, that can be from being so skinny – BMI 17,9). I have a very little excavation of the chest (a “hole” about 2 cms long and 1,5 cm wide, 1 cm deep). I am 37. I had an echocardiogram 9 years ago (after a car accident), it was all clear – I suspect any aortal problems should have appeared by that age if I had Marfan? I have had no heart issues, not even during pregnancy and labour. I had thorough eye tests before laser surgery 10 years ago and no lens misplacement was mentioned. Should I be worried at all?

    Locsoló K Anna

    June 12, 2015 at 12:33 pm

    • Hello Locsoló K Anna,

      At first sight I would say that you age suggests that you likely have not much too worry about regarding Marfan syndrome.
      However, hour description suggests that there are many factors that need to evaluated, I am not able to do that.

      Your obviously don’t pass the Marfan syndrome hand test, but I am not sure regarding the systemic test, see:

      I hope this is helpful for you?

      Best wishes + greetings from The Netherlands!

  55. Hello Martin!
    I am a 18 yo boy.
    I am able to do C and D and I have a pectus carinatum and glasses.
    I am 1,74 meter like my father and 55 kilograms.
    Have I possibly Marfan syndrome?
    Sorry for my English (I am french).


    August 9, 2015 at 5:31 pm

  56. Hello corentin,

    Even though the combination (C + D+ pc + low body-mass index) does meet a Marfan stereotype, this does not necessarily mean that you likely have Marfan syndrome.

    After all, you do not pass the Marfan syndrome hand test… and… if you don’t have any other Marfan stereotypes then you probably don’t have Marfan.

    I hope these considerations are somehow useful to you?



    August 9, 2015 at 11:26 pm

    • Thank you! You are very helpfull!


      August 10, 2015 at 10:43 am

  57. Years ago I convinced myself I had Marfans. I asked my Dr and she brushed it off. I can do C and D. My wing span is 62 and I’m 5’8-5’9. I measured my hand from tip of middle finger to bottom of hand and it is 7 1/2 almost 8 inches. I have huge palms, big long narrow feet, huge hands, extreme nearsightedness with lattice degeneration. I now have POTS and Vasovagal. Echocardiogram is normal for 3 years now. I’m 33 yrs old. My dad is 6’5 with huge hands, feet, all of his tests came back normal. I don’t know if I just get my huge features from that or marfans


    August 25, 2015 at 8:13 pm

  58. Hello, I first learned about Marfan syndrome a couple years ago and I realized I had many of the symptoms. I scored a 28 on the test (can’t do f, h, or j). I am 6 foot 1 and expected to grow much more, I am 16. I am very skinny and flexible and weight 130 pounds. Also, I have very long limbs and I am nearsighted. Though, to my knowledge I do not have any heart or lung problems. I do have problems with posture and my chest does stick out a bit. I feel like there is a lot of evidence to support that I could have Marfan syndrome, but there is one problem. After telling my parents what I had found out, they didn’t think much of it because thinness runs in our family. Am I being a hypochondriac and overthinking this? I don’t know. How can I convince my parents that we should look into this? Thank you for all your help.


    October 14, 2015 at 6:21 am

    • Hello Anonymous,

      Maybe you can show the ‘Marfan syndrome hand test’ to your parents, and see how they score on the test; if they hardly score any points that would significantly raise the chance for you to have Marfan syndrome (assuming that your score of 28 is justified).

      Your are welcome to report the outcome here.

      Best wishes from The Netherlands! 🙂


      October 14, 2015 at 6:00 pm

  59. Thanks for the quick response! My Mom got a score of 0. My Dad’s arm span does exceed his height, but only by about two inches (ratio of about 1.02). He may be able to pass part A, I’m not sure. If he passed part A, his total score would be 8 (0 if not).


    October 15, 2015 at 1:04 am

  60. Hi,
    I have 15 year old twins, boy and girl, both can score high on the hand test, son full score he is very flexible, daughter is not so flexible so only 28. Both have to wear glasses. My daughter has been having back pain for over a year and has now been referred to a geneticist for assessment for Marfan’s but I am wondering if I should be having my son checked out or would this follow if my daughter has Marfan’s?

    Fiona Heritage

    November 3, 2015 at 12:04 pm

    • Hello Fiona,

      Sounds like your twins both pass the Marfan syndrome hand test easily; your daughter’s back pain sounds like a serious issue that should induce attention for the possibility that she (and likely her brother as well) could very well have Marfan syndrome.

      Maybe it would be interesting for the geneticist to hear your experience with this test, because I am sure that the geneticist will be able to judge whether Marfan syndrome is indeed involved.

      Anyway, you are welcome to report the outcome of the consultation!

      Take care + best wishes!


      November 3, 2015 at 2:42 pm

  61. Hello. I stumbled upon marfan syndrome a few years back and have become consumed by the thoughts of having it. Cant get it off my mind every single day. I’m a 33 year old male 6 foot 1 inch tall (father 5’10 mother 5’7 but grandfather was the same height as myself) and weight 185 pounds and thinly built. Heres my list of traits as detailed as i can possibly get and id greatly appreciate your opinion….

    -mild dextroscoliosis of about 15 degrees (sporadic bad lower back pain but don’t know if its from this)
    -lower back stretch marks but nowhere else
    -myopia at exactly -3 diopters
    -more of a barrel chest then say protrusion or indentation
    -upper to lower segment ratio is .89
    -arm span to height ratio is 1:1
    -had braces when I was younger but do not have a high narrow palate
    -not hypermobile at all
    -only score a 4 on the hand test “d” and that’s even borderline (when attempting the wrist test if I point my hand upwards then I pass but if my hand is parallel to the ground then I don’t pass it)
    -no family history of marfans or any heart related sudden deaths
    -hand length is only 10.8% of total height
    -hit growth spurt later then peers (about 16) and so I went from being shorter than everyone to as tall or taller rather quickly (from what I understand, puberty tends to come early in marfan syndrome but I don’t know the significance just figured id add this detail)
    -i do not have spondylolisthesis
    -i have thin fingers but i don’t know if they would necessarily qualify as arachnodactyly. my middle finger length 3.56 inches and palm length is 4.31 inches and palm width is 3.65 inches.
    -hand and feet are wide, not narrow
    -do not have reduced elbow extension
    -internal hip rotation, anterior pelvic tilt, lordosis (i know these aren’t specific to marfans but still muskuloskeletal so i wanted to add these details)
    -no apparent facial features
    -no hernias or pneumorothorax

    Earlier this year i proceeded to have testing done. First i went for the slit lamp exam and was told i didn’t have the eye symptoms. Then i went to the cardiologist and had my echo which apparently came back fine. He said “my tissues look strong” and according to the report my aortic root is normal at 3.3cm and no other abnormalities. I then went to the marfan “specialist” (geneticist) who seemed completely outdated and uninterested. She did not do a thorough evaluation at all but said she doesn’t think i have it.

    What concerns me most is that combination of lower back stretch marks (exactly like the ones shown on google images) combined with scoliosis and slightly thin wrists. Also, everything ive read about states that cardiovascular symptoms tend to begin at an early age usually by early 20’s. Would i have had at least some kind of evidence of the cardiovascular symptoms show up on echo by now or not necessarily? Thanks for taking the time out to read my post and any feedback would be great.

    • Hello Chris,

      Thank you for your detailed summary.

      Obviously, you don’t pass the Marfan syndrome hand test… and I have derived quite a few other contraindications from your report:

      – the numbers that you shared indicate that you don’t have arachnodactly (your score is not even close to my Marfan criterium arachnodactyly, see:;
      – your body-mass index is normal;
      – no heart problems at the age of 33;
      – no red flags during your consult with a “Marfan specialist”

      Also, I have the impression that you also do not pass the ‘systemic score’ test (I think you score only 3 points?), see:

      Therefore I think your chance to have Marfan syndrome is close to zero; also, I could add that the combination of three factors which made you worry is not really indicative for Marfan syndrome – inside the systemic score this specific combination results in no more than 3 points, with only 3 of the ‘minor’ clues involved (your myopia of -3 is formally not high enough, though it can be recognized to represent a borderline clue).

      Hopefully this feedback will help you to ease your mind at least a little bit?

      Greets, Martijn.


      November 19, 2015 at 7:35 pm

  62. Thank you for your quick response Martijn. I feel somewhat better although I still cant seem to shake my doubts. I don’t know what my actual systemic score would be since nobody scanned me for acetabular protrusion or dural ectasia. And I don’t know if my barrel chest would be classified as a pectus deformity. Its a horrible way to live every single day thinking that I have this disorder but not being able to find out for sure and move on either way. Id like to ask you one last question that i forgot to mention previously having to do with the cardiovascular system. I did some fairly heavy weight training for about 12 years on and off (prior to having any knowledge of marfan syndrome of course) and so i was wondering whether or not that would have impacted my cardiovascular system if i did indeed have marfans, or not necessarily. In certain pieces of literature that ive read up on it has been said that cardiovascular signs appear at an early age (at least some sort of abnormality) in everyone with the disorder and in others ive read that these manifestations can begin later in life. I also wonder if this theory could be a product of late diagnosis in which the cardiovascular abnormalities were there all along but simply went unnoticed. Any info you have on this that would be so appreciated and id like to thank you again sincerely for your help

    • Hi Chris,

      If you have been involved in 12 years of weight lifting without being confronted with heart trouble… than one could say that you have a pretty, strong healthy heart!

      NOTICE: Heart trouble is the major concern involving Marfan syndrome, so I think this prior experience of yours ads to your (considerable) list of contraindications,

      (Sorry for the late follow-up response)



      January 3, 2016 at 2:53 pm

  63. I had my 35 year old daughter take your test and have a question concerning the results. She scored 16 on the test. She scored for everything except A and B. She said her arm span was as long as her height of 5″10″. On A she is not the tallest in the family but is the tallest woman. Her hand length was 11.5% of her height. So, she did not pass the test but is only 1 point off. The question concerns what you wrote about scoring on all 3 hand dimensions. I don’t quite understand what that means in her case. Does that mean there is a 25% chance of a false diagnosis? False diagnosis of what?

    Here is a little more information: She has a systemic score of 7. Mild scoliosis, flat feet, positive thumb and wrist signs, mild pectus excavatum, and marfanoid features. She also has lower back pain but has never been tested for dural ectasia. She is going to have an echo done on her heart and meet with a cardiologist soon. She also has a positive gorlin sign and positive reverse-namaskar sign. She has one swan neck deformity in her little finger.

    My 16 year old grandson easily scored a 9 and I only checked a few things. I wasn’t able to give him the full test but suspect he will score higher. For the purposes of your test, does a 16 year old need a score of 17 or 18 to pass?

    Thank you for this test.


    December 9, 2015 at 7:20 pm

    • Hello Vicki,

      First of all, if your daughter has a systemic score of 7… then it is very good to know that a meeting with a cardiologist has been scheduled.

      Regarding your daughter’s hand test, your report of 16 points sounds quite like the result of just a cautious
      check-up… but since you also mentioned that she is border line to pass for item A, I think it would be fair to say that your daughter is very close to passing the hand test.

      Now, regarding the hand dimensions: I only meant to refer to that in the perspective that the hand test includes three dimensions of the hand:

      – morphology (items A, B & D)
      – motorics (items C, G, H, I & J)
      – skin (items E & F)

      Since Marfan syndrome concerns a multi-system disorder, one could in the evaluation of the Marfan hand syndrome test scoring result also consider whether all three dimensions of the hand have attributed in the scores.

      So, when translating this to your daughter’s score of 16 points: since your daughter does score points in all three dimensions of the hand… this puts even more solid ground that your daughter’s hands are likely very typical for Marfan syndrome. And combined with a systemic score of 7 the chance for a false-positive appears to be close to zero for your daughter, so I think it should be just a matter of time for your daughter to have an official diagnosis for Marfan – which should open doors more easily whenever needed.

      (By the way, a swan-neck deformity is actually much more typical for Ehler-Danlos syndrome [EDS], which is also known for people to have a “Marfanoid” appearance; so, I think part of the diagnosis process could be to rule out EDS)

      I hope this all makes sense?

      PS. For your 16-year old son I would recommend to use the adult criterium for the 17 points to pass the test.


      January 3, 2016 at 3:24 pm

      • Thank you very much for your very helpful answer to my questions. She has had her echo and met with a doctor who was recommended by the Marfan Foundation. Her heart is fine except for mild mitral valve regurgitaion. This relieved us very much. The doctor said that she did not have Marfan Syndrome but diagnosed her with Ehlers-Danlos, Hypermobility type. We always felt that she fit the symptoms of Ehlers-Danlos more than Marfan Syndrome. Because of her diagnosis, it is highly likely that my 16 year old grandson also has Ehlers-Danlos.

        Your test was helpful in showing us if we were on the right path for a diagnosis. I wish that we had found it years ago when we started trying to find out what was wrong. Because of the large overlap between Marfans and Ehlers-Danlos, I feel that your hand test is pretty accurate. Thank you.


        January 14, 2016 at 10:55 pm

  64. I score 7 on the test. When I make a fist, the thumb does not exceed the ulnar border. I have a positive wrist sign. My question is about the a. I am taller than my parents, but my hand length is 10.97% of my height. Would my hand length be borderline or not.


    December 24, 2015 at 2:49 am

  65. Hi, would a 10.97% be considered borderline for A.


    December 25, 2015 at 7:20 am

    • No, 10,97% is actually pretty far away from the requirement of 11.5%.

      Anyway, thanks for asking superman!!!


      January 3, 2016 at 2:43 pm

  66. Hello. I’ve just come across this extremely useful site whilst doing the cardinal sin of ‘own medical research’…..
    My son is 14 (15 in 6 weeks( and has developed a very sudden onset of deep, angry looking stretch marks across his back (not attributed to weight loss/ gain). He is growing (as normal teenagers do), so I originally out it down to this. However he also has quite a concave chest, is tall (nearly 6ft – I am 5’3 and his dad 5’10). He is also asthmatic (mild).
    I am unsure of his hand test as I do not want to alarm him unnecessarily by asking all these different things! As teenagers can be self conscious enough I don’t want to alert him to the fact that a concave chest and stretch marks may be seen as abnormal (if that makes sense). I completely understand that you are not intending to make clinical diagnosis for people – was just looking for any advice please? Many thanks


    December 29, 2015 at 6:29 pm

    • Hi Emma,

      Maybe you can try to get his attention in a playful manner? For example, maybe you can for a start inform your son that you red an interesting article involving extraordinary hand features such as the wrist sign, and you can show him that you are not able to do it yourself… but you can tell him that some people can; this might sound like a funny challenge for your son to wonder whether he is capable to connect the thumb & pinky finger when putten around the wrist of the other hand, etc.

      Would that be helpful?

      Greetings, Martijn.


      January 3, 2016 at 2:40 pm

  67. I think I can add another point of confirmation for this test. I am a very tall man for my country (194 cm), a whole 20 cm taller than my father and 16 cm taller than my tallest brother. My hand is 19.7 cm long, so ratio A is 10.15. My arm span is, curiously, precisely 10 times my hand length, 197 cm, so ratio B is 1.015. I have a wrist sign (D, which seems to me very common among tall people in general), and I can sort of produce a thumb sign (C), but not easily at all and not without some pain. It’s much, much easier to do on the left hand, I guess because I stretch my thumb in that direction hundreds of times a day, to reach the left shift key on my keyboard (which is very bad typewriting!). No hand skin quality points. I have G and H. I also have J, as my elbows bend backwards very much, which freaks out my friends and prevents me from using a bow and arrow. My wrist also bends very much, but that might be because I’m gay ;). So, my final score is 11 if the thumb sign is counted, or 7 if not. Moreover, I have slight scoliosis and myopia and my tendons and ligaments are really weak and prone to inflammation. I had a heart exam very recently, which found that my aorta is on the small side of normal, and the valves close perfectly. So, no Marfan syndrome for me, as predicted from this test.


    January 22, 2016 at 5:51 pm

    • Hello NRMNRM,

      Thanks for sharing your summary.

      Interesting to see that you appear to score quite a few point on both the hand test (only 11 or 7) and the Marfan syndrome systemic test (my estimate would be only 5 or 4 – ), but obviously both results are not high enough to qualify for Marfan syndrome.

      Good to hear that your heart condition is fine.

      Best wishes from The Netherlands!


      January 24, 2016 at 6:25 pm

  68. I came to this page because I have always been relatively thin but have mysterious stretch marks all over my body. (I have Lyme disease and have been diagnosed with bartonella, as well, which can cause rashes that look like stretch marks; however, I still think I have a lot more than is typical even with bartonella.) In any case, I’m curious about this test because I seem to meet many of the criteria…though I have questions about them.

    First off, I don’t think I have the typical Marfan bone structure and I am not as thin looking as many of the people with Marfan who turn up in web searches. (Many of them look like they could be mistaken for having an eating disorder, although it’s evidently just their body type.)

    I am 5’10-3/4″ tall, so on the tall side of average. I’m a little taller than my father, but not by a great deal. He has a similar body type.

    Regarding the hand tests:

    A. I measured the length of my hands at 8″, so my ratio is just below the stated threshold.
    B. My wingspan is a couple of inches longer than I am tall.
    C. My I can close my thumb inside of my fingers, but I can also close my hand easily with the thumb sticking about an inch outside of my first like the picture. I’m not sure how this one is supposed to work.
    D. This is easy for me, with about 1/2″ overlap of my pinky finger over my thumb.
    E. The skin on the back of my hand stretches just like this–and so does that of everyone I’ve asked to try it. I’m not sure how this works. My finger skin stretches more than other people’s, but not as much as the photo.
    G. Can’t do this at all. Ouch.
    H. Halfway.
    I. I can do this easily.
    J. Nope. Not that bendy.

  69. Hi thank you for putting this information up. I came to this page as I just got back from the eye doctor. Over all my eye health is good but when examining the photo taken she said that there were some squiggly blood vessels that is usually caused by chronically high or even low blood pressure. I certainly do not have high blood pressure, every time I check it is in the below than normal range. About seven years ago I went to the doctor because of some pain in my left arm and new that could be a sign of heart disease so I just wanted to be checked to be on the safe side. She ran some tests and said that I had Mitral valve Prolapse and wanted to put me on Beta Blockers which I declined at the time because it really did not bother me that much so I didn’t think it was necessary. But with this eye results it got me thinking that my low blood pressure is not healthy so I started to do a search on MVP and found this page. I do tend to faint is stressful situations or when getting blood drawn. My feet and hands are always cold and I do feel tired most of the time. For this test I can do B (arm span is about 2 inches longer), I can do C with some effort, D not a problem at all, E, I, and H. Growing up I was extremely thin and more flexible than I am now. The only thing is that I am only 5′ 7 and my brother, sister, and father are all over 6′. Also, my back is extremely stiff, and I have suffered from back pain frequently. My teeth were extremely crowded when I had braces they had to remove multiple teeth because my jaw was too small. I’m just curious is it still likely that I can have Marfan even though I am only 5’7″? Should I be concerned?


    May 18, 2016 at 4:07 pm

  70. I am 54 years old and recently feel a slight pressure under my sternum. It concerned me a little and I have considered going to the doctor but I really don’t have a general doctor. After googling what could cause that pressure feeling I came across marfan syndrome. I am 5’8″ and weigh 125. I have always been this. I have scoliosis and kyphosis and my sternum is tilted so that the left side of my chest protrudes farther than the right. (I thought maybe this was putting pressure causing the feeling of pressure). My bottom teeth have been crooked all my life because of crowding and I have and overbite so that my bottom teeth hit behind my top teeth. My arm span is 5’11”. My thumb goes beyond my hand when doing the thumb in fist test. And my thumb overlaps my entire pinky fingernail when doing the wrist test. There is no other history of Marfan in my family. I have a slight mitral valve prolapse with no regurgitation. I am not flexible. I hate the thought of going to a doctor and sounding like I am a hypochondriac. This all started with the slight pressure feeling in my chest and I thought it was stress or pressure from my weird sternum.

    • Hello Heidi L. Williams,

      Your descriptions sounds like you score at least 16 points on the Marfan syndrome hand test. Now, combined with the other issues which you described (scoliosis, kyphosis, sternum, slight mitral valve prolapse) I think it would be wise to search for the risks at your age.

      On the other hand, not sure… but 54 years sounds like an a-typical age to get involved with a diagnosis for Marfan syndrome, so at first sight I see not much need to get into a rush regarding further action,


      Anyway, thanks for sharing your thoughts! 🙂


      July 11, 2016 at 5:30 pm

      • Thank you for your quick reply. I go for my annual eye exam tomorrow, I am myopic and have 20/600 vision. I am wondering, are there different degrees to marfan?

        Heidi L Williams

        July 11, 2016 at 5:54 pm

  71. Hi, i have always been tall (about 6’2″ or 6’3″ and thin). I can do the wrist test on my left wrist, and maybe on the right too, though not as easily as the left. my hands are about 11% of my body height, maybe a bit less, though my fingers are quite skinny. my arm span to height ratio is about 1.01. i think my upper/lower segment ratio is either 0.95 or 1.

    what makes me wonder though is that I do have what i’d consider to be mild pectus excavatum, i have sleep apnea that i use a cpap for (diagnosed around age 21), i had a hernia that was operated on about 9 years ago, i wore braces, and i am nearsighted. i don’t think i have any of the other features on the systemic calculator. my grandfather died of a heart attack (i believe) in his early 50s.

    anyways, curious to hear your thoughts. this website is a good resource.

    November 21, 2016 at 5:58 pm

    • Hello Southern Man,

      Your report might implicate that you that do not score any points for this hand test (even aspect d is doubtful, your arm span & upper/lower segment ratio can be described as ‘normal’).

      The combination of features that you described is probably not typical for Marfan syndrome, especially since you described every aspect mentioned to be ‘mild’; sleep apnea and hernia are therefore likely not related to Marfan.

      Thanks for your report anyway! 🙂


      January 23, 2017 at 7:09 pm

  72. Hey!

    I’m 180 cm tall (5-15 cm taller than my parents and my brother) and extremely thin. 56 kgs. Arm span is around 183-185 cm. My hand is like 15 cm (from middle finger down to where the palm starts, sorry for my english). I passed C & D when it comes to the hand test, most likely the B too? I also got pectus carinatum, not very sever but I’ll be taking a surgery for that due to the cosmetics within the next month. I can also bend the tip of my thumb a little backward, likewise can my mom but not my father nor my brother or sister. Don’t know about anyone else in my family having marfan, nor any signs. I’m the only one with long fingers, arms. Also got pectus carinatum also known as pegion chest.

    I’m a bit taller than my parents and siblings, also got “different hands” as my fingers and arms are longer. My brother is also quite thin like me, but probably got a few extra kilos than me. I don’t have any problems with my vision that I’m aware of. Can you help me do the math when it comes to B, and wether you think I might have marfan or not? Thanks in advance, appreciate your answers ❤


    January 23, 2017 at 1:44 am

    • Hello Tho,

      Apparently you don’t qualify for B (1.85m/1.80m = 1.028, which is clearly below the 1.05 criterium), and therefore it looks like you don’t qualify for this hand test. Your info suggests that you might have +5 ‘systemic score’, which is considerable but likely not high enough to qualify for Marfan, see:

      By the way, I don’t understand your “15 cm” description… because if that is correct your hands are extremely short relative to your height (I have considered the option that you only tried to describe your palm length, but 15 cm would be extremely long for that aspect).

      I hope this is helpful so far, thanks for your report!


      January 23, 2017 at 6:58 pm

      • Yeah I messed up with the hand length. My middle finger is 9 cm. My palm is is 10 (from start of middle finger to the start of the palm, vertically).

        Here’s a picture (not my hand, but my measurements):
        My fingers are thin and long. Did I mention that my brother is my twin? Not sure if that makes any difference, but he doesn’t have that long and thin fingers as I do, nor any chest deformity. I’m as mentioned earlier a bit taller than him, and got longer arm span than him. Not sure if that makes it even more like marfan?

        Really appreciate you answering ❤


        January 23, 2017 at 9:10 pm

  73. So these symptoms are the most common symptoms for those with marfan syndrome. Do you know wether or not having long fingers and toes and having pectus carinatum could be another kind of syndrome as well? That’s the kind of symptoms I got. Can also bend the tip of my thumb, but nothing more than that really. Arm span is larger than my height though.


    January 27, 2017 at 5:38 pm

  74. Hi, I came across Marfans after a physical therapist mentioned concerns of eds to me. I had a orthopedic dr and rheumatologist both tell me there is no way I have that. I’m not flexible, never was. I think pt thought that because my knees can bend just slightly inward. Anyway, I’m 32, female, 5’8, 140lbs, always have been tall, long arms, hands, legs. My hand measured at 7.5 inches (11.1% body height) my brother and dad taller than me, but my mom is only 5 feet. My arm span is 2 inches more than my height (1.03), I can do the wrist sign, but I have very thin wrists. I can almost pull my thumb through to do the thumb test, but it hurts a lot to do that. Can’t do any of the others. I have mild pectus exvatcum and I found out 4 years ago from an echocardiogram that I have mild tricuspid valve regurgitation. I’m nearsighted and had an ultrasound type test on my eyes 6 months ago and everything was normal. I am not sure if the roof of my mouth is high, nobody has ever mentioned it and I’ve had lots of dental work done, teeth were slightly crowded. I don’t have any other symptoms, the facial descriptions are a little confusing so not sure about those. I’m seeing my doctor soon and requesting another echocardiogram, but since I had this test when I was 28, would something have shown up by then? Is mild tricuspid valve regurgitation something indicative of marfans?


    May 17, 2017 at 12:13 am

    • Hello Danelle,

      Sorry, your questions involving the heart go beyond my expertise.

      Wishing you good luck with the new echocardiogram!


      May 17, 2017 at 12:07 pm

  75. Hi
    My 19 year old son had corrective surgery for scoliosis last year. The paediatrician suggested that there was a small chance of Marfan syndrome based on his tall lean stature allied to the scoliosis. He also had several teeth extracted a few years ago (does not have an arched palate) and there is some evidence of skin stria. He has no chest wall deformity, no indication of Dural ectasia or history of heart problems. He scores 12 on the hand test (b&d)
    My eldest son also displays some skeletal features of marfans and also scores 9 on the hand test (c,d &g).
    I am 51 in perfect health and score 0 on the hand test. My wife is 48 and had SVT in 2011 which was resolved by ablation. The consultant confirmed that her heart was structurally sound at the time and the ablation has prevented any further palpitations. She also scores 0 on the hand test but is hypermobile in her knee joints. Like me she shows no signs of the skeletal manifestations associated with Marfans and under the Ghent scoring system we only score 1 point each for myopia (I am sure this is down to our age).
    There is no history of heart trouble on my side of the family although my wife was adopted and does not know her family medical background although she has recently made contact with her natural father who appears in rude health at 70.
    I am concerned that both my sons display marfanoid features and that either my wife or I maybe asymptomatic given it is highly unlikely for 2 siblings to have marfans in the absence of a parent?
    My question is this……is it possible to score 0 on the hand test, 1 on the systemic score for marfans, have no major underlying health problems in middle age and still have marfans? I appreciate that only a full diagnostic work up can answer this but what is the likelihood?


    June 8, 2017 at 12:19 am

    • Re: “My question is this……is it possible to score 0 on the hand test, 1 on the systemic score for marfans, have no major underlying health problems in middle age and still have marfans? I appreciate that only a full diagnostic work up can answer this but what is the likelihood?”

      Hello Dave208,

      Sorry, I do not have enough expertise to give any well founded answer to your question; however, my intuitive estimate would be that at middle age the chance is very small for you (or your wife) to have Marfan syndrome without knowing it – I think the chance could be below 1%.

      Be aware: in about 25% of Marfan cased the syndrome is caused by a spontaneous genetic mutation. So, by principle it is probably only a bit unusual to see Marfan syndrome ocure in two brothers with non-Marfan parents but this does not provide a basis to suspect that one of the parents should have Marfan syndrome.


      PS. Again, your question goes (far) beyond my expertise so I would welcome others very much to give more precise input – whenever they can, of course.


      June 12, 2017 at 6:01 pm

      • Thanks for getting back to me. It is possible that I score 8 on the test as I am the tallest in my family at 6 ft 2 inches although all males on my side of the family are around 6 ft and I guess somebody has to be tallest? From your studies are you saying that 19 out of 20 people confirmed with MFS would pass the hand test thereby meaning that my wife and I only have a c 5% of having MFS? Have any more recent studies been done to confirm the veracity of the study?


        June 13, 2017 at 8:23 pm

  76. Hi there! Saw something regarding Marfan Syndrome on TV and can’t help but wonder if I have it. I scored a 5 on the Marfan Hand Test.
    A. Negative: my hand is 10.7% of my height.
    B. Negative: Arm span ratio is 1.01
    C. I am a little unsure about this one, because if I do it naturally, my thumb does not stick out at all. However, if I try to extend it, the thumb kinda shows but it is not comfortable (so I didn’t count this).
    D. Postive: My wrists are super small so I can easily do this –> 4 points
    E. Negative
    F. Negative
    G. Postive: only with my left thumb—> 1 point
    H. Negative
    I. Negative
    J. Negative

    I am convinced that I have Marfans because I am 26, female, rather skinny, 43 kg and 160.2 cm tall. I am roughly my mom’s height, and quite a bit shorter than my dad. No protuding chests or anything like that. Long fingers (finger length 7.7cm, palm length: 9.5cm, palm breadth: 7cm). My elbow is hypermobile and I have a very mild mitral valve prolapse. Doctors never brought Marfans up, but does it sound like I can have marfans?

    Please give me some advice.


    July 5, 2017 at 10:44 am

    • Hello paris_saigin,

      Even though you did not pass the Marfan hand test, the proportions of your hand shape do provide additional clues on top of the 5 point score on the test.
      Because the proportions are quite similar to the average hand shape proportions which I have found in a small sample of Marfans – see the table inside the following article:

      So, I think I can understand your conviction because the combination of proportion, motorics & mild MVP appear to be significant.
      Before jumping into conclusions… maybe it would be wise for you check out other factors that are involved with Marfan via a systemic score assessment, see:


      PS. Be aware: based on the details which you described so far you are far away from passing the systemic score (you appear to score only 2, while 7 or higher is required).


      July 5, 2017 at 11:54 pm

      • Hi martijnvanmensvoort !

        Wow, thank you so much for getting back to me! I am glad you responded. I just checked out the hand shape proportion table from that article that you sent me and it does seem like my hand proportion fit the criteria of someone with Marfans. However, my father has long fingers as well, so maybe it could be genetic? I also came across this finger/hands ratio testing and in this one, I do not match the proportions of someone with Marfan’s :

        I don’t really know the difference between this table and the one you sent me.

        I did the systemic score assessment and I got a 2 just like you had predicted. I could only do the wrist test and I have a very mild MVP. My doctor never mentioned Marfan’s either so I don’t know if these clues are big concerns?

        Once again, thank you so much for replying. I would appreciate if you have any further remarks and comments!

  77. Hello. I scored 0 points and I have mild pectus excavatum (1 cm indent) and mild flat feet. I have no eye problems. I am 186cm tall and I’m 17. My dad has pectus excavatum too but he doesn’t have any marfan symptoms and problems. I think he would score 0 points too. He is 193cm. What are my chances to have it? All is in proportion and I have no worrying facial features. Above in comments you mentioned some case about marfan with 0 points…. What characteristics did she have and how did she know she has marfan. Thank you so much for replying. I will check my heart but what are my chances?

    • Also in C my nail sticks out 0.5 cm (around half of the nail) if i try with all my force and I got told I have no scoliosis but a scoliotic posture (that I need to work on posture and that spine was good). How did that other woman with 0 points found out she had marfans. Did an ecg it was all normal and I will do echo tomorrow. My elbows arent hypermobile they go around 180° just as they are supposed to. I might have had rickets as a child, as I have mild form of x legs. Do I have it?


      July 30, 2017 at 8:18 pm

      • Just checked the systematic test and I think I would score 2. Pectis excavatum and flat feet. I have stretch marks but I believe its the result of increasing my arm from 27 to 32 cm circumference in 4-5 months and increasing my chest muscle. They are where the chest muscle meets the deltoids. They showed up 2 months ago. So I didn’t think I should rule the stretch marks as a result of this. A buddy of mine slightly older has had them for 1 year and they are all over his arm and where mine are, but I have only like 4-5 0.5cm lines where as he has them bigger and a lot more. Thank you for replying.

    • Btw I am a guy.


      July 30, 2017 at 10:10 pm

  78. Hello Worried,

    Sounds like you just described that you score just 2 points for the Marfan syndrome systemic score (where 7 points are required to pass) & 0 points for the Marfan syndrome hand test (where 16 points are required to pass).

    Looks like two strong contraindications regarding your (apparent) fear for having Marfan syndrome!

    I hope this will give you a little peace at rest regarding the outcome of your ECG test, but please feel free to share the outcome.

    I hope this is helpful?

    PS. Pectus excavatum is known to have a high prevalence in first degree family members, so this probably explains directly why you have this condition (which is likely a 3rd contraindication regarding Marfan syndrome, a 4th contraindication concerns your body height which is considerably lower than your father’s body height).


    July 30, 2017 at 10:10 pm

    • I do not know how to thank you enough, kind sir. You brought my soul to peace. Had this on my mind for a week. 😀
      Also thank you for replying to every comment on this website, and in such short notice 🙂
      Btw I did an ECG, it was normal, I just need to do an echocardiogram tomorrow and will post the results.
      With all my heart, I thank you for what you are doing, and love from Macedonia ❤


      July 30, 2017 at 10:23 pm

      • Did an echocardiogram it was normal 🙂


        July 31, 2017 at 10:09 pm

      • Good to hear that for you, thanks for sharing! 🙂


        August 3, 2017 at 12:05 am

  79. I am male and only 5ft 8in tall but my hand is 8 inches long. My fingers are crooked and 3.5 inches long. They bend quite far back but not 90 degrees. I don’t have any other symptoms. could i have marfans?


    August 2, 2017 at 7:52 pm

    • Hello Andy,

      If your body height is not (much) larger compared to your family members, then you would not score any points for hand sign a.

      Even though your hand length to body height ratio does meet one part of the criterium involved with hand shape sign a, your body height is at first sight atypical for a male Marfan syndrome and your finger length to palm length ratio (0,77) is also atypical for Marfan syndrome. Therefore I perceive your info to include hardly any basis for you to have Marfan syndrome.



      August 3, 2017 at 12:19 am

  80. Hello,

    Thank you for providing this test.
    I came across this because one of my friend has been diagnosed Marfan and I wanted to know more.
    However, this got me a bit worried.

    I’m a 33 year old man.
    I’m tall (approximately 1m92 (could be one cm more or less): father 1m87 and mother 1m76) and I weigh 75kg.
    Regarding A, my hands are 20.5 cm long
    Regarding B, I reach 1m97 when I spread my arms.
    I’m not really sure the thumb test is positive, since I can reach the border of my hand but not really go that far.
    C is easily achieved,

    So I guess it should be considered as negative but I got worried. What do you think?

    Thanks a lot!
    Greetings from Switzerland

    • Sorry, I meant D is easily achieved.
      Everything else is negative, I am not flexible at all!! Neither is my skin…

      Worried Thom

      August 3, 2017 at 1:56 am

      • Hello Worried Thom,

        Since you clearly do not pass for A nor for B, and you only appear to score points for item d for sure, you probably have nothing to worry about – since a score of 4 (or 8 when C is counted) is clearly less than half the points you need to pass the hand test.

        So I can confirm your conclusion that you can consider yourself to score ‘negative’ for this test indeed.

        Problem solved, I hope?

        Anyway, thanks for asking – cheers! 🙂


        November 8, 2017 at 7:01 pm

  81. Hello. I am afraid I might have Marfan.
    I’m 21 and I’m a boy.
    I am taller than both my parents(my dad is 174cm, my mom is 159cm).
    My height is 1.81 in the morning and 1.79 at night. I read on internet that average Marfan height for boys is 191.3 +- 9 cm.
    My finger length index is 0.89-0.90. My hand length is 19-19.2 cm. (10.72% of body height if I use my height at night).
    My arm span is 178 cm which is < than my height. My dad has 179 cm arm span which is a lot more than his height.
    My upper to lower segment is between: 0.904-0.97. (0.904 is the worst case)
    I have mild myopia: -1 diopters developed in childhood. My mom has the same diopters.
    I dont have flat feet. My chest is normal.
    My teeth are pretty straight but I have a deep bite(My dentist said is common).
    I dont think I have facial characterstics except my lower jaw being a little bit smaller.
    My feet are below 15% of body height. My feet are a bit longer than my dad's. I can wear the same shoe size as him easily.
    I have little silver stretch marks on buttocks I think from growth spurt at puberty. I had a late puberty.(I read on internet 40% of boys develop stretch marks at puberty).
    I can do D, E(i am not too sure), G(in the past i couldn't but I trained myself), H, I. A lot of my friends are a lot more mobile than me.
    The only thing that worries me a lot is I have very tiny wrists(like my mom's) and longer fingers(0.89-0.90 ratio). Also i am very underweight right now: 55 kg because this year I extracted my wisdom teeth and couldn't eat too much.
    I am 100% sure my parents dont have Marfan's. My dad has very big wrists. My mom has small wrists like me but shorter than average fingers.

    Do u think I should worry? I suffer from health anxiety and depression because of this. None of my doctors told me anything about Marfan.


    September 20, 2017 at 8:10 pm

    • Finger length: 8.4 cm
      Palm breadth: 7.9-8.2 cm.
      Palm length: 10.6-10.8 cm.

      Worst case finger length index: 0.908
      Best case: 0.88


      September 20, 2017 at 8:17 pm

      • Also i dont have reduced elbow extension. My knees are normal.


        September 20, 2017 at 8:31 pm

    • Hi there andreiandrei,

      Thanks for sharing your thoughts on this.

      Your body-mass index is worrisome indeed and this probably explains your narrow wrists; however, in the perspective of Marfan syndrome you have nothing to worry about (since you appear to score no more than 6-8 point; I have also made a check for you regarding the systemic score where you probably score not much more than 2 point while 7 are required there for a positive score there).

      I hope this will help you ease your mind.

      Best wishes + good luck with taking care of your anxiety and depression.

      Warm greetings to you from The Netherlands! 🙂


      November 8, 2017 at 7:19 pm

  82. My fingers are fatter than my mom’s but slender than my dad’s. Both my mom and dad are obese.


    September 20, 2017 at 8:39 pm

  83. Hello I’m 19
    I’m 167 cm arm span ratio 1.04 but my mom is 170 and father is 186 they also have large arm span
    I have the exact same hands with mom my hand ratio is %11, she cant do wrist sign because of her weight but can do thumb sign but I can do C and D
    Guess A and B are borderline
    And in A it says taller than family + long hands so confused a little bit
    I am so scared because I have stretch marks and myopia
    Cardiologist said nothing about aorta in echo just said long valve with no pulposion but taschycardia in low levels
    I haven’t heard any marfan in my family
    But most of the people have large hands as I do also I played basketball in puberty can it affect the longness of my arms


    October 8, 2017 at 3:02 pm

    • Hello scaredb,

      If the details which you shared are accurate you only score for C and D = 8 points, by far not enough to pass the hand test.

      Have you tried the systemic test:

      (I think you do not score beyond 4 or 5, if so then I think you very likely do not have Marfan syndrome)



      October 8, 2017 at 11:30 pm

      • dank je !!!


        October 25, 2017 at 10:42 pm

  84. Hello, I got a 27 out of 32 with A, B, C, D, E, and G. I know that the probability that I have Marfan Syndrome is quite high according to this test, so I was wondering how accurate it is. If it helps, I don’t have flat feet and I’m a half inch from 6’1. But I do have a misshapen ribcage, and my family has a history of heart diseases (no one, to my knowledge, has ever had Marfan Syndrome Do you recommend that I get further testing? Thanks.


    October 26, 2017 at 5:42 am

    • Hello Doof,

      A score of 27 provides a solid basis to proceed with a thorough follow-up check on the systemic score (where you appear to score at least 4 points of the required 7), see:

      Just let me know if you need more assistance for further evaluation after you have assessed the systemic score.

      Take care! 🙂


      November 8, 2017 at 7:26 pm

  85. Hi..My daughter is 15. She can do C and D, though C with some difficulty. She has to somewhat force it. Her wingspan is 5’11” and she is 5’9″ (1.036). She weighs about 118 lbs. Her hands are 11.5% of total height, but she is my height (5’9″), her father (5’11”) and her brother (6’1″). So she is not excessively taller than other members.She is also a late bloomer and has not yet had her period (she is a competitive swimmer). She has long feet and they are flat. We are a tall, slim family. No one has been tested for marfan, so we don’t know. She has none of the other characteristics mentioned above. I only learned about this syndrome while reading a book. Since she has longer hands and feet, I just got worried. I think her systemic score would be maximum 5 if i was to include both wrist and thumb sign and 3 otherwise I am worried since she does intense exercise everyday. No stretch marks. Going for eye exam, but at best mild myopia. I have weak eyes as do all my siblings.

  86. Please help me. I am a 13 year old girl whos birthday has just passed 7 months ago. I only got 4 points from D on this test, however I have many of the signs of Marfan syndrome that is posted on various websites. My shoulders is about a quarter of my height and it worries me a lot as I have very narrow shoulders compared to my height. My fingers are verry narrow and low. I have an very small face with a small pointed chin that is considered beautiful or ideal in asian standard. I have an overbite I am currently fixing with braces and have a slight problem with an hunched back, althought a hunched been has been a problem throughout my whole family. In contrast to symptoms of Marfans, I have arched feet and seem to have no heart problems. Since, I was an early bird by 6 weeks, the eye doctor has told me that my eyes didn’t fully develop, so I am far sighted, which I think doesn’t have anything to do with being a Marfan. Some important background information is that I might be going thorugh puberty. I reached my first growth spurt of about 10-20cm summer 2 years ago and continued to grow till now, recieving my first period, seemingly only growing taller, but not wider. My weight is very underweight as I am 87 pounds and 165ish cms, although I eat a lot. I’ve always been skinny since birth, but I used to be always the shortest in class, although always having noticably long legs. No one else in my family is realtively tall, but they are all skinny, but with normal shoulders. I only get sick about 1-2 a year, only ever with a fever that I usually get over with just a good nights rest and some advil. I’m not very athletically active, but I feel very healthy. Please help me. I want to know if I have Marfan Syndrome,

    • Hello Jazz Gu,

      First of all, sounds like you are definitely in puberty!

      Assuming that you are right about not have any heart problem + combined with your score for point D only (which in your case might be the result of puberty), your odds do not appear to point towards Marfan syndrome.


      PS. I have the impression that you also do not even score half of points required at the systemic test for Marfan syndrome, please check the details for confirmation here:

  87. hello i do not speak English very well, i’m 16 years old and I have long arms and long fingers and a light pectus excavatum, i do stack the size of my father and some of my uncles are taller than me. I only succeeded the D the E and the G in Forçan. Thank you for giving me more information

  89. Hello,

    I just found this website and am not sure if you are still there….

    I am a 51 yr old female and I am pretty darn positive I have Marfans. I come from a tall family, and we believe my maternal grandfather may have had Marfans, my mother does not. I was diagnosed by a cardiologist due to my 8′ wing-span vs my 5′ 9″ height (I’ve shrunk 1″ – used to be 5’10”) but have never had the genetic testing done. I passed every letter in your hand test but “F” therefore scoring 26, as well as having a very deep pectus excavatum (my sternum is 4″ from my spine) and 2 scoliosis curvatures in my spine. My eyes are fine (PTL!) but my hearing is progressively declining. I was told by an ENT that my eustachian tubes were collapsing due to the “connective tissue disorder” Marfans.

    Have you ever heard of this in your experience with Marfan Syndrome? I am fearful for my ability to hear in the future..

    If you have any advice, steps should I take from here….?


    January 18, 2020 at 9:31 pm

    • Hi Caroly,

      Since you have been diagnosed by a cardiologist, I presume that your heart condition is just fine?

      Not sure that I can give you a proper advice related to your hearing issue, but maybe it would simply be best for you to get an official diagnosis for Marfan syndrome because this might open doors to get access to Marfan specialists who have proper expertise involving the issues related to hearing loss in Marfan syndrome.

      Best wishes + thanks for your question.


      January 19, 2020 at 12:55 am

      • Wow, thank you for replying so quickly! I was very curious if you had ever heard of hearing loss due to Marfans.

        The cardiologist sees me every year to keep an eye on all my valves. I am not allowed to get my heart rate over 140bpm. My lungs and heart don’t work well together, as I have very limited lung space so my heart works extra hard because I can’t breathe properly due to rib cage deformation and my heart is located very close to the inside of my ribs so when it beats hard, it bumps my ribs…painful!

        Thank you for your advice. I will seek genetic testing to see what comes up and hopefully someone will be able to direct me to the proper resources for my situation.

        Thanks again!


        January 19, 2020 at 1:16 am

  90. Greatings from BIH.🙂 Can you tell me what does it mean if I can cover with thumb 70% of nail in picture d)? I see on hand test picture that thumb finger reach far more than I can.


    February 2, 2021 at 5:00 pm

    • Hi Boris,

      This probably only indicates that you would then probably have an extreme variation; however, such variations in isolation do not have any sort of specified meaning in terms of the associated diagnostics matters.

      Greetings from The Netherlands!


      February 2, 2021 at 5:25 pm

      • Thank you very much on quick reply..i can also do hand motoric test j). It doesn’t make any difference in combination with fact that I can cover 70 % of nail with thumb? I ask because you sad that in isolation it doesn’t have diagnostic significance fact that I can cover partially (70%) nail on little finger.


        February 2, 2021 at 9:33 pm

      • My english is maybe not clear enough. My apollogies. I hope you understood a question. Thank you very much.


        February 2, 2021 at 9:41 pm

      • Boris, if you only have sign d and sign j then you arrive at only 5 points – which would not be enough to pass the Marfan syndrome hand test.


        February 2, 2021 at 10:00 pm

      • Ok..thanks.. I must to write that It’s hard to say does someone can give himself 4 points if cannot fullfill the whole task on this hand test. I see that people in old comment also don’t know what to do especcially with c and d. I wonder about this test couple of days and I cannot figure out exact points.


        February 2, 2021 at 10:19 pm

  91. I scored 2 with i and g, but I can only do both with my left hand and I kinda forced my thumb with g. When it comes to my immediate family I am tall, I’m 19 years old 6ft and 176 pounds, but when it comes to my whole family like cousins and uncles I’m in between I have cousins that are taller or almost my height. I also have moderate pectus excavatum, nearsightedness, flat feet, and stretch marks but with the stretch marks I thinks it’s due to recent muscle and weight because they’re recent, and both my mom and older sister have flat feet and my older sister also has nearsightedness. My arm span is equal to or just shorter than my height. And I’m also certain no one in my entire family has marfan cause they show no symptoms. Never had any heart or lung issues, I also don’t have scoliosis, or a high arched palate and I think my toes might be a bit long but I’m not sure but my feet are pretty small I’m only a size 9 – 9 1/2.


    August 22, 2021 at 8:46 am

    • Hi Jonah,

      Do you actually have Marfan syndrome?
      Or are just interested to consider it as a realistic option?

      Anyway, thanks for your input


      August 22, 2021 at 11:18 am

      • No I have not been tested for Marfan syndrome, I just wanted to see if I have enough of the symptoms to maybe consider getting tested
