Adactylia, Unilateral

Graham et al. (1986) described adult female twins with unilateral terminal transverse defects affecting the left hand in one and the right hand in the other. The latter woman had a daughter with a unilateral transverse defect affecting the left hand. The hand anomaly was characterized by absence of the terminal portions of digits 2 to 5 with a mildly hypoplastic thumb. Tiny nail remnants were evident on the digital stumps. No soft tissue syndactyly was present. The other hand and both feet were clinically and radiologically normal in each of the 3 persons. No other similar families were found in the literature.
