The disease "deafness and onychodystrophy" (DOD) is characterized by congen
ital hearing impairment and dystrophic or absent nails and teeth. The autos
omal dominant form of the disorder has been previously reported only in one
family. We describe here another family in which three members in three ge
nerations (a girl, her mother, and her maternal grandfather) were affected
with DOD. Our finding is consistent with an autosomal dominant mode of inhe
ritance and confirms autosomal dominant DOD (DDOD, MIM *124480) as a recogn
izable clinical entity.
