Abstract
The dermatoglyphics of 7 patients with Rubinstein-Taybi syndrome [a disease whose main features include mental retardation and peculiar facies] and their 17 family members were compared with those of 250 male and 250 female controls. The most striking dermatoglyphic findings of the patients were the increased frequency of arches, decreased frequency of ulnar loops and reduced ridge-counts on the fingertips, particularly on the thumbs, lower a-b ridge-counts, increased frequency of I, Ir, II loops, e, f and t" triradii, decreased frequency of H loops and tb triradii on the palms, increased frequency of If loops, decreased frequency of I loops, f and p triradii on the soles. The relatives of the patients had more radial loops on the fingertips, I and Hr loops and t'' triradii on the palms, II, III, loops, f and z triradii on the soles. Applicability of this study to diagnosis of Rubinstein-Taybi disease is discussed.
