A complex syndrome characterized mainly by aural, oral, and mandibular developmental anomalies which may vary from mild to severe and frequently involve one side of the body. Vertebral anomalies, epibulbar epidermoids, mental retardation, and numerous other anomalies are frequently associated. Orofacial anomalies differ from those in mandibulofacial dysostosis which are usually symmetrical. The presence of hypertelorism may indicate aneuploidy.
