A very rare variant of acrofacial dysostosis with characteristics of mandibulofacial dysostosis and limb anomalies. It has been described in less than ten patients. The mandibulofacial dysostosis consists of retrognathism, complete or occult posterior cleft palate and anomalies of the external ears. Limb anomalies consist of split-foot deformity with syndactyly of some toes. The condition is transmitted as an autosomal dominant trait with variable penetrance and expressivity.
