Dermatoglyphic study in children with phenylketonuria.

Dermatoglyphic findings in 19 patients with phenylketonuria (11 male and 8 female), 39 of their relatives (18 female and 21 male) and 500 controls (TRC) were not statistically significant among the three groups studied. There was no definite relationship between the phenylketonuric gene and the dermatoglyphic patterns. The parents of half the phenylketonuria cases are not consanguineous; thus the phenylketonuria gene may be more frequent in Turkey than other European countries.
