Dermatoglyphics of 100 phenylketonurics and 200 controls matched for ethnic origin and sex were compared. The present study of dermatoglyphics in phenylketonurics is consistent with results showing that single gene disorders have fewer and less striking anomalies of ridge development than diseases with gross chromosomal defects.
Analysis revealed a decreased frequency of whorl patterns on the finger tips and a wider mean summed atd angle among affected females as compared to normal females. The males showed no significant differences. Limited as they were to one sex, the differences seem unlikely to be attributable to the effect of the phenylketonuric gene.
