by pits and/or sinuses of the lower lip, and cleft lip and/or cleft palate (CL/P,
CP). It is the most common cleft syndrome. For a phenotypic description and a discussion
of genetic heterogeneity of van der Woude syndrome, see VWS1 (119300). See also orofacial
cleft-13 (OFC13; 613857) for a susceptibility locus mapping to chromosome 1p33.;
Inheritance : Autosomal dominant;
Molecular basis : Caused by mutation in the grainyhead-like-3 gene (GRHL3, 608317.0001);
