TOP 10 Hand Signs indicative for Fragile-X syndrome!

leave a comment »

A pair of hands of a female person who has Fragile-X syndrome.



This TOP 10 is composed from a list of 34 hand signs for Fragile-X syndrome, and the hand signs are ranked by Log Odds Ratio – which are calculated from the prevalence (%) among people who have Fragile-X syndrome & controls.

1 – Sydney line [Log Odds Ratio = +3.63]
2 – Ridge line A: ends btw. finger 5 & heart line [Log Odds Ratio = + 3.44]
3 – Triradius b: missing (or ridge line B is ‘abortive’) [Log Odds Ratio = +3.32]
4 – Fingerprints: radial loop on thumb [Log Odds Ratio = +3.28]
5 – Ridge line C: ‘abortive’ [end close to triradius c] [Log Odds Ratio = +3.22]
6 – Simian crease [Log Odds Ratio = +3.08]
7 – Double-jointed thumbs (hypermobility) [Log Odds Ratio = +2.73]
8 – Fingerprints: arch on ring finger [Log Odds Ratio = +2.24]
9 – Fingerprints: arch on pinky finger (in males only) [Log Odds Ratio = +2.14]
10 – Palmar triradius d: missing [Log Odds Ratio = +2.10]

It is interesting to notice here that 7 of the 10 hand signs relate to the upper half of the hand (the zone below the finger + the fingerprints), and additionally the major palmar lines (head line & heart line often manifest as a simian crease or Sydney line) play a significant role.

And it is fascinating to notice that these TOP 10 hand signs significant for Fragile-X syndrome is a mix of hand features that relate to both the palm (7 hand signs) and fingers (3 hand signs).

And these 10 hand signs also relate to five of the seven perspectives described by Multi-Perspective Palm Reading, including: the dermatoglyphics (7 hand signs), major palmar lines (2 hand signs), and hand motorics (1 hand sign).

NOTICE: At a later moment a likewise TOP 10 will be presented for hand signs that are indicative for autism – about 3% of people who have autism also have fragile-X syndrome!

The Sydney Line & the Simian Crease are like ‘Fraternal Twins’!

leave a comment »

Normal palm creases - simian crease - Sydney line.

 Many people are fimiliar with the concept of a simian crease, but there is a likewise fascinating line that has a likewise significance: the Sydney line. In modern medical science both the simian crease & the Sydney line became known as a ‘minor physical anomaly’!

In a 1967 Belgian study Vrydagh-Laoureux pointed out that next to the well-known simian crease (or ‘simian line’ – which became well-known for it’s significance in Down syndrome), there is actually another hand line variant that is associated with related to Down’s syndrome. In the Belgian study this line was described as an ‘extended proximal palmar crease’.

NOTICE: In the traditional palmistry vocabulary this line is often described as: an ‘extended’ or very long head line.

Interestingly, only one year later Australian researchers (Purvis-Smith & Menser, 1968) found that this fascinating palmar line is also frequently found in the hands of patients with congenital rubella – and from that point this ‘fraternal twins line’ of the simian crease has been named: the Sydney line (or sometimes named: ‘Sydney crease’). This twin-analogy could become valuable because many people often find it difficult to discriminate a simian line from a Sydney line!

Example of the Sydney line presented by Purvis-Smith (1972).

Purvis-Smith defined the Sydney line as follows:

“A sydney line occurs where the proximal transverse crease extends beyond the midline axis of the fifth finger towards the ulnar border of the palm the ulnar border of the palm.” (Purvis-Smith, 1972) 


At the end of 20 century a new trend became appearant within the medical scientific community. Researchers began study so-called ‘minor physical anomalies‘ – which concern typically harmless inborn physical markers (that are typically associated with a specific prenatal period) – that have been associated in various disorders.

And especially in the 21 century this approach became popular among researchers who are studying the etiology of e.g. autism, ADHD, Down syndrome, hypoxia & schizophrenia.


Multi-Perspective Palm Reading demonstrates how the Sydney line & simian crease can be understood as a likewise hand line markers. Because (so far) a wide range of studies indicates that in far most diseases & syndromes where the simian crease has been recognized as a significant body marker… the Sydney line became recognized as a likewise significant body marker.

This pattern is seen e.g. in: diabetes mellitus, Down syndrome, fragile-X syndrome, rheumatoid arthritis, and schizophrenia!

Finally, discussion in the Modern Hand Reading Forum have shown that – despite the fact that a Sydney line and a simian line can never be observed in one hand – for many people it quite hard to discriminate a Sydney line from a simian crease. The picture below presents a few fundamental clues which could become helpful to understand the essential components of both lines.

NOTICE: A ‘common hand’ is featured with a life line [I], a head line [II], and a heart line [III]; and various hand line variations can be summarized with the following formulas [IIx = extended head line; II+III = simian crease]:


Obviously, there is a fundamental difference between the Sydney line and simian crease – therefore it appears more appropriate to describe them as ’fraternal twin lines’ instead of ‘identical twin lines’; because while they have a common nature… their manifestion shape is definitiely not identical.

More details are discussed in the following discussion:
