28 Characteristics of the hand in Fragile X syndrome (Xq27).

How to recognize the hand in Fragile X syndrome?

Alexander Rodewald presented in 1986 the very first ‘phantom picture’ describing the typical hand characteristics in Fragile X syndrome (e.g. including the simian crease or Sydney line). But more detailed ‘phantom pictures’ were never presented after the A. Rodewald et al. (1986) publication. However, this month (february 2010) an updated ‘phantom picture’ has become available – featuring 28 characteristics of the hand in Fragile X syndrome (+ a couple of other hand related characteristics).

What are typical hand characteristics in Fragile X syndrome?

HAND LINES:
A common characteristic is the presence of the famous ‘simian line‘; an alternative is the presence of a Sydney line.

DERMATOGLYPHICS:
Here one should especially notice the fingerprints of the 3rd finger (and the 2nd + 4th finger); often these demonstrate the presence of ‘radial loop’ patterns and/or arch patterns (the normal ‘ulnar loop’ patterns are less common in Fragile X syndrome) – combined with a ‘transverse’ pattern in the palmar ridge lines in the distal palmar zone.

HAND SHAPE:
The palm width (hand breadth) is relatively broad, and the palm length is usually a bit short. Finger length is relatively long compared to the palm length, but slightly short compared to the palm breadth.

NOTICE: The author of the new ‘phantom picture’ for Fragile X syndrome described a specific guideline which states that in most cases of Fragile X syndrome certain combinations of the 28 characteristics are found in both the fingers AND the palm of the hand!

How to recognize the hand in Down syndrome - 27 characteristics.

How to recognize the hand in Down syndrome?

Lionel Sharples Penrose introduced in 1963 in the magazine Nature the first ‘phantom picture’ for the hand in Down syndrome. The picture described some of the typical characteristics of the hand in Down syndrome – including the ‘simian crease’. Later more detailed ‘phantom pictures’ were presented by Schaumann & Alter (1976), and Rodewald (1981).

In januari 2010 a more detailed version became available – describing 27 characteristics of the hand in Down’s syndrome!

What are the most typical hand characteristics in Down’s syndrome?

HAND LINES:
A common characteristic is the presence of the famous ‘simian line‘; an alternative is the presence of another unusual hand line: the Sydney line.

DERMATOGLYPHICS:
Here one should especially notice the hypothenar zone of the hand (in palmistry a.k.a. ‘mount of moon’); usually this zone a large ‘ulnar loop’ pattern combined with a high positioned palmar axial triradius.

HAND SHAPE:
Short fingers (thumb and pinky finger are often abnormally short) + a square shaped palm.

NOTICE: The author of the new ‘phantom picture’ for Down syndrome described a specific guideline which states that in all cases of Down syndrome certain combinations of the 27 characteristics are found in both the fingers AND the palm of the hand!

The Sydney line: an underestimated hand mark in Palmistry!

Many years ago the Sydney line was discovered as another hand line mark for Down’s syndrome – the other handmark is the ‘famous’ simian crease. How come that the diagnostic significance of the Sydney line is still underestimated?

This article describes an overview of the global palmistry- & scientific research related to the Sydney line.

In 1967 a Belgian study on Down’s syndrome was published which pointed out that besides the ‘famous’ simian line, an ‘extended proximal palmar crease’ is also a significant feature in Down’s syndrome.

One year later some researchers from Sydney, Australia (Purvis-Smith & Menser, 1968) reported that this fascinating palmar line is also frequently found in the hands of patients with congenital rubella – from that point researchers adopted the name used by researchers from Sydney: the name of the ‘Sydney line’ was established!

S.G. Purvis-Smith (Australian researcher) described 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.”

Dozens of studies have confirmed the diagnostic significance of the Sydney line – sometimes the discriminative value is even higher compared to the simian crease! The significance of the Sydney line can be related to various medical problems (such as: Down’s syndrome, leukemia, Alzheimer dementia), and psychological problems (in general: developmental problems at young ages).

The simian line is often found in Down syndrome, but also frequently seen in Asian populations.

The simian line

The simian line is a ‘notorious’ hand crease and well-known for it’s significance in Down’s syndrome – more than half of these people have a simian line in 1 or both hands, while only about 1% of healthy populations have a simian line. Nevertheless, this line is also frequently observed in the hands of certain ethnic population – especially in Asians!

In 1866, R.L. Down discovered in 1906 the relationship between the simian crease and Down’s syndrome. The simian line is also know as: the ‘simian crease’ or ‘single palmar transverse crease’.

‘Healthy hands’ with the simian line usually do not have the other stereotypical hand features related related to Down syndrome are missing (examples of other Down syndrome-related hand features are: a short thumb, curved little finger, certain dermatoglyphic patterns in the palm and fingerprints).

In some (Asian) populations is extraordinary frequently seen, such as: Pygmies: 34.7 %; Gypsies: 14.3 %; Chinese: 13.0 %; Koreans: 11.2 % – more percentages are presented in the full article.

The simian line

The simian line has been well-known since R.L. Down discovered in 1906 it’s significance in Down syndrome – it was his father who actually discovered the Down syndrome in 1866. Since then the simian line has been studied in many other aspects of life. The full article presents an overview of the most relevant aspects of the simian line.

HOW TO RECOGNIZE A SIMIAN LINE?

A typical ‘simian line’ is characterized by the presence of a single line that runs across the palm of the hand. People normally have three major hand creases in their palms. Only when the simian line is present there are only two major creases. By the way, the simian line can manifest in various line constellations in the palm: some examples are present at the left.

SIMIAN LINE SYNONYMS

The most popular alternative names for the ‘simian line’ are:

  • simian crease
  • single palmar transverse crease
  • simian fold
  • WHAT DOES A SIMIAN LINE MEAN?

    The simian line appears to be related to rich scala of medical problems. Wrongdiagnosis.com presents a list of 93 causes of the simian crease, including Down syndrome, fragile-x syndrome and the cat-cry syndrome. However, one should never forget that the simian line (simian crease) is also found in the hands of perfectly healthy people!
