Dermatoglyphics in Cri du Chat syndrome.

The dermatoglyphics of 33 Japanese (20 females and 13 males) with Cri du Chat syndrome were compared with 544 male and 129 female controls. In these cases, 18 cases were described only with regard to simian crease and distal axial triradius. It was found that these patients showed high frequencies of certain characteristics such as whorl pattern, arch pattern, thenar pattern, bilateral simian creases and distally displaced axial triradii on both palms (t').
