Ulnar Hypoplasia With Lobster-Claw Deformity Of Feet
Clinical Features
Van den Berghe et al. (1978) described a family in which 4 males in 2 generations showed almost complete absence of the ulna and of fingers 2 to 5, together with lobster-claw deformity of the feet. Conductor females showed slight hypoplasia of the ulnar side of the hand and mild syndactyly of the toes.
InheritanceVan den Berghe et al. (1978) suggested X-linked recessive or autosomal dominant sex-influenced transmission as the possible mode of inheritance in the family with 4 males affected with absence of the ulna and lobster-claw deformity of the feet.
