3 Hand Charts for Fragile-X syndrome!
Fragile-X (Xq27.3), a.k.a. Martin-Bell syndrome, is a genetic condition that causes a range of developmental problems including learning disabilities and cognitive impairment. Usually, males are more severely affected by this disorder than females.
Prevalence: fragile X affects 1 in 4,000 males and 1 in 6,000 females of all races and ethnic groups; about 1 in 259 women carry fragile X and could pass it to their children.
Quite a few detailed hand charts are available for fragile-X 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) or Sydney line.
(The first hand chart below also illustrates the significance of various proportions of the hand size in fragile-X 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 fragile-X syndrome 28 hand signs are being reported; however the article where this hand chart is presented actually already describes 36+ hand signs in fragile-X syndrome, involving 8 out 9 levels of the hand.
All significant hand signs listed above for fragile-X syndrome together cover eight out of the nine perspectives of the hand as defined according Multi-Perspective Hand Reading (including hand level 1, 2, 3, 4, 5, 6, 8 & 9).
A summary of the most significant hand sign combinations in fragile-X syndrome is described here:
