Antley-Bixler syndrome is a congenital malformation syndrome that primarily manifests with craniofacial abnormalities but may include skeletal malformations. Some cases have been shown to be caused by fibroblast growth factor receptor 2 mutations and, recently, it was revealed that others are caused by mutations in the electron donor enzyme.
