title: Familial occurrence of severe ulnar aplasia and lobster claw feet: a new syndrome.
abstract: In this paper we describe a previously unreported association of ulnar defect and lobster-claw deformity of the feet, occurring in four males belonging to two generations of the same family. Minor expression of the same ulnar reduction defect in female relatives suggests X-linked recessive inheritance, but an autosomal dominant with irregular expression cannot be excluded.
