Postaxial acrofacial dysostosis syndrome

Abstract

Three patients with a postaxial acrofacial syndrome are presented; the features of these and three other previously described examples are set forth. The facies can be strikingly similar to that of the Treacher Collins syndrome. The limb deficiencies are postaxial, with absence or incomplete development of the fifth digital rays in both the upper and lower limbs. Accessory nipples have been found in most of the patients. The nature of the limb deficiencies and the accessory nipples help to distinguish this condition from Nager AFD. All of the children have normal intelligence and development; most show normal growth. All of the six cases have occurred sporadically.
