Tests & Diagnosis

How is van der Woude syndrome diagnosed?

Van der Woude syndrome should be considered in every child born with a cleft lip and/or palate. A clinical evaluation by a medical geneticist is generally performed to document all relevant clinical findings. In addition, the parents should be examined for isolated lip pits, cleft palate, and hypodontia (missing teeth). To make a clinical diagnosis of Van der Woude syndrome, at least one of the following findings must be present:[1]
  • Lip pits and cleft lip AND/OR palate (CLP). Lip pits must be paramedian on the lower lip, and can include mounds with a sinus tract leading from a mucous gland of the lip.

  • Lip pits alone and a first-degree relative with CLP

  • CLP and a first-degree relative with lip pits

Genetic testing for mutations in the IRF6 gene can also be used to diagnose this condition.[1] GeneTests lists the names of laboratories that are performing genetic testing for van der Woude syndrome.
