Dermatoglyphics findings in families with X-linked hypohidrotic(or anhidrotic) ectodermal dysplasia(HED).
Data from finger, palmar, and plantar prints of 8 males with X-linked hypohidrotic ectodermal dysplasia(HED), 8 carrier mothers, 7 sisters, and 1 carrier grandmother are compared with data from 552 controls. The patients with HED and the carrier females had higher incidence of arches on the fingertips, of t" triradii, of hypothenar patterns (especially ulnar loops), and of transversal direction of the main lines on the palms than the control individuals did. The affected males were also characterized by severe hypoplasia and/or dysplasia of the dermal ridges ("ridge flattening"); the carrier females also showed ridge flattening and hypoplasia.
