Van der Woude syndrome
From Wikipedia, the free encyclopedia
| ICD-10 | Q38.0 |
|---|
Van Der Woude syndrome (VDWS) consists of the following characteristics: cleft lip with or without cleft palate, isolated cleft palate, pits or mucous cysts on the lower lip, and hypodontia. It is the most common syndromic form of cleft lip and palate (CLP), accounting for 2% of all CLP cases (usually CLP is nonsyndromic).
[edit] Genetics
VDWS is caused by mutations of the IRF6 gene, located on chromosome 1 at 1q32-q41. (Popliteal pterygium syndrome can also be caused by mutations of this gene.)
In 2002 Kondo et al. described a pair of monozygotic twins discordant for VDWS whose parents did not have the disorder.
