Autosomal recessive inheritance of susceptibility to tinea imbricata

Familial distribution of chronic tinea imbricata in an untreated Melanesian population was consistent with a genetic predisposition to this disease. The pattern suggested that susceptibility to chronic Trichophyton concentricum infection is recessively inherited and controlled by genes at a single autosomal locus. In married couples there was no concordance of the disease above that expected by chance and the observed segregation of tinea imbricata accorded well with that predicted by the genetic hypothesis.
