3 Hand Charts for Edwards syndrome!
Edwards syndrome, also called trisomy 18 or trisomy E, is an chromosomal condition that causes severe birth defects in newborns; many babies born with trisomy 18 do not live past one month of age.
Prevalence: estimated at 1 in 6,000 live births.
Quite a few detailed hand charts are available for Edwards syndrome; most charts describe the significance of various typical features inside especially the dermatoglyphics, which manifest often combined with a simian line (= single transverse flexion crease) and/or a single interphalangeal crease on the pinky finger.
NOTICE: Individual hand features described below should not get associated in isolation with any theme; only combinations involving multiple hand levels have potential for diagnostic purposes.

Other significant hand signs (not reported inside the hand charts):
A clenched hand with overlapping fingers (89%) is characteristically seen in Edwards syndrome; typically, the index finger is overlapping the third finger and the fifth finger is overlapping the fourth finger - see picture below (source: Wikipedia).
Distally implanted (52%), underdeveloped thumbs [= thumb hypoplasia] is another typical characteristic , and the thumb may even be missing completey [= thumb aplasia] (source: Corience.org). Retroflexible thumbs (25%) are also very common (source: A.I Taylor, 1968).
Underdevelopment of the nails [= hypoplastic nails] is also very common: 63%; long, hyperconvex nails are also relatively common: 17% (source: A.I Taylor, 1968).
All significant hand signs listed above for Edwards syndrome together cover five out of the nine perspectives of the hand as defined according Multi-Perspective Hand Reading (including hand level 2, 5, 7, 8 & 9).
