Do you have a radial loop fingerprint? In people who have radial loop fingerprints these are usually spotted on the index finger(s); in the field of hand reading it is a common beliew to associate radial loops with ‘people who do not go with the flow’ – refering to the fact that the radial loop represents sort of the opposite of the much more common ulnar loops. But what are the facts and how do they develop?

The latest research points out that a radial loops might have a connection with the Big Five personality dimension Extraverion (see picture below).

This article presents 10 facts about radial loops:

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

Phantom picture of the hand in Fragile X syndrome!

In 1986 A. Rodewald et al. presented the first ‘phantom picture’ describing the typical hand characteristics in Fragile X syndrome (e.g. hand calluses & flexible finger phalange joints). But more detailed ‘phantom pictures’ were never presented since then. This month (february 2010) a more detailed updated version of the visualisation became available – featuring 28 characteristics of the hand in Fragile’s syndrome!

What are the most common hand characteristics in Fragile X syndrome?

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

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.

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 Fragilex 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!
