Dermatoglyphics in Down's syndrome. I

Abstract

A group of Down's syndrome patients and a normal control population were studied in an attempt to determine which of several existing index scores based on dermal patterns could be most efficiently used as a diagnostic aid. The 183 mongoloid individuals were included in the study on clinical grounds and had 47 chromosomes with trisomy‐21, Relative frequencies of dermal patterns on palms, fingers and soles were determined and the discriminative efficiency of pattern areas was investigated.
