Van der Woude Syndrome

Van der Woude syndrome consists of clefting of the lip, palate, or both. Lip pits are seen in 80% of patients, and mucous cysts of the lower lip also may be observed, although they occur less frequently. The disorder is variable, and affected family members often show diverse phenotypic expression. Hypodontia may be present, and individuals may be missing central and lateral incisors, canines and/or bicuspids.
