In order to avoid misunderstandings, a brief description of each of the 9 hand lines in the picture, is given below:

Line 1 = extra crease on the distal phalange (beyond the distal interphalangeal crease)
Line 2 = extra crease on the middle phalange (in 1 or more fingers)
Line 3 = single crease on the pinky finger
Line 4 = extra crease on the thumb
Line 5 = ‘hockey-stick crease’
Line 6 = simian crease
Line 7 = Sydney crease
Line 8 = transverse hypothenar crease
Line 9 = secondary creases: unusually high density

The names of the 9 disorders are:

A = Alagille syndrome (= genetic disorder related to e.g. the liver, heart & kidney)
B = Coffin-Lowry syndrome (= genetic disorder: e.g. mental problems, health)
C = Down syndrome (= genetic disorder: trisomy 21, e.g. mental handicap, health)
F = Edward syndrome (= genetic disorder: trisomy 18, e.g. low rate of survival)
D = Fetal alcohol syndrome (= caused by alcohol abuse during pregnancy)
E = Fragile-X syndrome (= genetic disorder: Xq27, e.g. mental handicap, autism)
G = Pit-Rogers-Dank syndrome (= e.g. growth disorder, mental retardation)
H = Schizophrenia (= psychiatric disorder)
I = Sickle Cell Diseases (= blood disorder)

The QUIZ-task is very simple:
‘Which line (in the picture above) belongs to which disorder?’

(You can submit your answers as a response to this blog post, but you can also discuss the details at the Modern Hand Reading Forum, at:   The ‘Weird-Hand-Lines QUIZ’ – part 2)

By the way, quite a few ”clues’ for finding the right connections are provided in the section MEDICAL HAND ANALYSIS.

A curved little finger is often seen in people who have autism or medical syndromes.

A curved little finger is often seen in people who have autism or medical syndromes.

How the ‘pinky’ (little finger) relates to autism:

The presence of small physical defects – such as a curved little finger (the ‘pinky’ or ‘pinkie’) – and the occurrence of autism often go together. This is concluded by Ozgen – Dutch researcher at the UMC Utrecht, The Netherlands.

The conclusion is the result of a meta-analysis of seven studies (published in the years: 1975-2005) in which the characteristics of 330 patients and 328 healthy controls are integrated. Ozgen became PhD on November 28, and July (2009) the results of her study are published in the journal ‘Molecular Psychiatry’.


Ozgen reports that the most significant physical defects related to autism are: (1) a ‘curved’ pinky finger, (2) toes slightly too far apart, (3) deformed ear lobes, (4) a higher palate, and (5) eyes slightly further apart.

In medical jargon the curved pinky (curved pinkie) is known as: clinodactlyly. Other common problems related to the pinky finger are: polydactyly (an extra pinky), camptodactyly (bent finger) & syndactyly (webbed fingers).

How surprizing is this research result on the ‘curved’ little finger really?

Maybe not so surprizing at all! For, in time a curved little finger has been related to up to over 60 medical syndromes, including: Klinefelter XXY syndrome, FAS: fetal alcohol syndrome (16% to 51%), and most common: Down syndrome (35% to 79%).

However, one should also noticed here that the ‘curved’ little finger can be seen in the hands of healthy people as well. Statistics for normal & healthy people reported for the ‘curved’ little finger vary from: 1% to 19.5%.
