6 Hand Charts for Down syndrome!
Down syndrome (DS), also called Trisomy 21, is a condition in which extra genetic material causes delays in the way a child develops, both mentally and physically.
Prevalence: estimated at 1 in 700 live births.
Quite a few detailed hand charts are available for Down 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 Sydney line and/or a single interphalangeal crease on the pinky finger.
(The first hand chart below also illustrates the significance of various proportions & the hand size in Down syndrome)
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):
Inside the first- and most detailed hand chart for Down syndrome 27 hand signs are being reported; however the article where this hand chart is presented actually already describes 32 hand signs in Down syndrome.
All significant hand signs listed above for Down syndrome together cover seven out of the nine perspectives of the hand as defined according Multi-Perspective Hand Reading (including hand level 2, 3, 4, 5, 7, 8 & 9).
A summary of the most significant hand sign combinations in Down syndrome is described here:
