General Discussion

IRF6-related disorders are a group of orofacial clefting disorders including Van der Woude syndrome (VWS) and popliteal pterygium syndrome (PPS). These conditions are caused by mutations in the interferon regulatory factor 6 (IRF6) gene.

Individuals with VWS are at the least severe end of the spectrum. They can have lip pits or cleft lip or cleft palate, or any combination of these anomalies. Individuals with PPS usually have the lip pits, cleft lip and/or cleft palate, with additional skin and limb abnormalities including webbed skin (pterygium) on the backs of both legs (popliteal) and between the legs (intercrural), malformation and/or genital anomalies, webbing or fusion of the fingers and/or toes (syndactyly), adhesion of upper and lower jaw (intraoral adhesions), and adhesion of upper and lower eyelids (ankyloblepharon). A cone-shaped fold of skin on the nail of the big toe is a characteristic finding in PPS.
