In 2004 Chinese researchers present a new approach to study the hand lines for biometric purposes. They applied a mathematical model on hand prints and were able to identify six types of palmar crease variations – based on the core characteristics of the three ‘major palmar lines’. Recently, in line with the Chinese research a new more advanced (PIC) model was introduced which e.g. describes 21 types of major hand line variations which are displayed in ‘a family tree of the major hand line types’: see the picture above.
Interestingly, the new study reports e.g. about a correlation between the palmar lines and intelligence (IQ): left hand vs. right hand asymmetries appear to be involved, plus a lower prevalence of MPA’s – such as the simian line & Sydney line).
More details are available in the article:
What can formations in hand lines reveal?
For more information about various aspects of the palmar lines the following book is recommended:
‘Anthropology of Crease Morphogenesis’.
NOTICE: The three major palmar lines concern:
– The ‘radial longitudinal crease’, in palmistry a.k.a. the ‘life line’;
– The ‘distal transversal crease’, in palmistry a.k.a. the ‘heart line’;
– The ‘proximal transveral crease’, in palmistry a.k.a. the ‘head line’.

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?
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!

In 1963 L.S. Penrose presented the first ‘phantom picture’ describing the typical hand characteristics in Down syndrome. More detailed ‘phantom pictures’ were presented by Schaumann & Alter (1976), Rodewald (1981). This month (2010) a more detailed updated version of the visualisation became available – featuring 27 characteristics of the hand in Down’s syndrome!

Researchers at the universities of Cambridge and Oxford believe that Albert Einstein showed signs of Asperger’s Syndrome.
Marianne Raschig was able to make a handprint of Albert Einstein’s hands in 1930. Does Einstein have the typical hand features that researchers have observed in autism?
|Albert Einstein’s handprints are presented at the bottom of this post (the high quality versions are available at: THE HANDS OF ALBERT EINSTEIN). Let’s take a look at the hand characteristics that have been associated with autism in varioius scientific studies:
2D:4D Finger ratio
Professor John T. Manning described in 2002 in his first book titled: ‘Digit Ratio‘ that the hand in autism is often characterised by a by a ‘2D:4D finger ratio’ of 0.94 of lower. Interestingly Albert Einstein’s digit ratio appeared to be close to 0.93!
Some Romanian researchers described in 2003 some significant results related to fingerprint asymmetries between the the right hand and the left hand. They described that they found that the hands of persons who have autism are often featured with more ‘arch’ fingerprints in the left hand and/or more ‘loop’ fingerprints in the right hand. Interestingly, Albert Einstein has 2 ‘loops’ (middle finger + pinky) in his right hand and only one ‘loop’ in his left hand (pinky)!
Unusual hand lines
In time various scientific studies have reported that the hand in autism is frequently featured with unsual palmar lines. The most important unusual palmar lines are: ‘the simian crease‘ & ‘the Sydney line‘. Interestingly, Albert Einstein has an (incomplete) Sydney line in his left hand!
No less than exactly 40 years ago articles in the famous Time Magazine and the Lancet revealed that certain characteristics in the hand lines can signal major medical problems. A few hand facts from 1969!
The patterns of the fingerprints and the palmar lines are established by the fourth fetal month of life in the womb, when the fetus’ hand is only a few millimeters long. The more conspicuous “flexion creases” (the palmist’s “heart, head and life lines”) are formed a month or two earlier.
In normal palms, the heart and head lines are separate and distinct, and neither extends clear across the palm. However, in many victims of Down’s syndrome, prenatal rubella, childhood leukemia, and even in Alzheimer dementia, the palmar lines are replaced by a Sydney line (see picture above), or a single “simian crease” (see picture below) – characteristics which are quite normal like that on a monkey’s palm!
