Van der Woude syndrome (VWS) is the most common syndromic form of cleft lip and palate. It is an autosomal dominant disorder characterized by pits and/or sinuses of the lower lip, cleft lip, cleft palate and uvular anomalies. Other findings may include ankyloglossia and hypodontia. VWS1 (MIM 119300) and VWS2 (MIM 606713) are caused by mutations in the IRF6 and GRHL3 genes, respectively.read more
