General Discussion

IRF6-related disorders include a spectrum of disorders caused by abnormalities in the interferon regulatory factor 6 (IRF6) gene. Van der Woude syndrome (VWS) is at the mild end of the spectrum and popliteal pterygium syndrome (PPS) is at the severe end of the spectrum. Individuals with VWS can have lip pits alone, cleft lip or cleft palate alone, or a combination of these anomalies.



The physical features associated with PPS include cleft lip and/or cleft palate, lower lip pits, webbed skin (pterygium) on the backs of both legs (popliteal) and between the legs (intercrural), malformation and/or underdevelopment of the genitals, 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 very distinctive finding in this condition.
