Abstract

Two unusual types of syndactyly in the same family; Cenani-Lenz type and «new» type versus severe type I syndactyly?: Cenani-Lenz syndactyly is a very rare syndrome where the syndactyly is totally disorganized with abnormal development of pattern formation of the hand. We report here an additional case of Cenani-Lenz syndactylism in a woman who has congenital cataract and an unusual type of duplication of big toes not described so far. She had a half cousin who had an unusual new type or severe type I syndactyly. It is not clear whether these two types of syndactyly present in this family may be coincidental or not.
