Scalp Defects And Postaxial Polydactyly

Fryns and Van den Berghe (1979) observed a kindred in which several persons had scalp defects and postaxial polydactyly type A. They raised the question of this being a single gene trait. One person had both, 4 had scalp defects only, and 3 had postaxial polydactyly only. Buttiens et al. (1985) reported a sporadic case.
