Dermatoglyphics in Prader-Willi syndrome.

The finger-, palm-and sole-prints of thirteen patients with Prader-Willi syndrome have been analysed. Some information has also been obtained from another case. The topological classification has been used for describing palms and soles. Frequencies of finger pattern types, data on finger ridge-count and maximal atd angles are included. Relevant published data has also been considered in making assessments. It is concluded from the evidence available that the dermatoglyphics of patients with the syndrome differ little, if at all, from those of the normal population. Pattern intensity on hands, and particularly feet, is low. Dermatoglyphics, therefore, are not a useful criterion in the diagnosis of the syndrome.
