Genetic inheritance of susceptibility to tinea imbricata

Abstract

Segregation analysis on 228 family pedigrees collected from a Papua New Guinean population provided data that strongly supported a previous report of an autosomal recessive pattern of inheritance of a susceptibility to tinea imbricata. The frequency of the susceptibility gene within the population studied was found to be 0.49±0.04, calculated on the assumption of an autosomal recessive mode of inheritance. However, in spite of the strong evidence in support of autosomal recessive inheritance, the possibility of autosomal dominant inheritance with reduced penetrance cannot be excluded.
