Genee-Wiedemann syndrome or disease

Related people

An extremely rare genetic mental retardation-multiple congenital anomalies syndrome. The facial characteristics include downward slanting palpebral fissures, cleft palate, micrognathia and malar hypoplasia, malformed ears and eyelids and a broad nasal ridge. Limb anomalies include shortened and bowed forearms, incompletely developed ulnar and radius bones, absence of 5th fingers and toes, and abnormal growth of the tibia and fibula bones. Other features include supernumerary vertebrae and other vertebral segmentation and rib defects, heart defects (patent ductus arteriosus, ventricular septal defect, ossium primum, and endocardial cushion defect), lung disease from chronic infection, supernumerary nipples, single umbilical artery, absence of the hemidiaphragm, and seizures. Mental retardation may be associated. Inheritance is believed to be autosomal recessive.

In his first description of 1969 Genée assumed the condition to be an extreme form of dysostosis mandibulofacialis. Wiedemann in 1973 described it as a separate entity.
