The very high positioned axial triradius provides an explantion for the fact that in het hands of people with Patau's syndrome (trisomy 13)
or Edward's syndrome (trisomie 18), the A-line has frequently a vertical progression towards the wrist: see figure B-2b + table B-1.
The other trisomies are usually featured with a horizontal progression of the A-line: see figure B-2c.
For in these syndromes the axial triradius is usually positioned a bit lower compared to Patau's syndrome (trisomy 13) and
Edward's syndrome (trisomy 18): see figure B-1.
On the basis of a dermatoglyphic analysis of the fingerprints, the various syndromes mentioned can be discriminated from each other very well:
see table B-1.
From the 'phantom picture' related to Down's syndrome (see: figure A-7 on page 5)
one can observe that Down's sydnrome is frequently featured with ulnar loops on all finger (possibly combined with a radial loop on the ringfinger.
Figuur B-3: 'phantom pictures'1 related to: Edward's syndrome (a),
Patau's syndrome (b) and Warkany's syndrome (c).
Edward's syndrome is usually featured with arch fingerprint patterns on all 10 fingers (possibly combined with a radial loop on the thumb):
see figure B-3a. NOTICE: in the hands of normal people a radial loop on the thumb is very rare.
Patau's syndrome is featured by a large number of arch patterns combined with radial loops on the ringfinger and the little finger:
see figure B-3b. NOTICE: in the hands of normal people this is a very rare combination.
Warkany's syndrome is frequently featured with arches combined with whorls: see figure B-3c.
NOTICE: In the hands of normal people the combination of arches and whorls is usually observed in less than 10%.
