A postaxial polydactyly-dental-vertebral syndrome.

Three patients with postaxial polydactyly and other abnormalities of the hands and feet, hypoplasia and fusion of the vertebral bodies, and dental abnormalities are reported. Two were sisters born to normal unrelated parents; the other patient was the male offspring of a consanguineous marriage. We suggest that this constellation of abnormalities represents a recessively inherited syndrome.
