Present nosology of the Cenani‐Lenz type of syndactyly

Abstract

Synostoses of the carpals and metacarpals with oligodactyly were noted in a man whose brother was similarly affected. Since the proband's two children are normal, autosomal recessive transmission is probable. Although abnormalities of the feet, and particularly radioulnar synostosis, are lacking, this malformation is comparable to the Cenani-Lenz type of syndactyly. Interfamilial variations of published cases suggest subdivision of a new nosologic group.
