The WAGR syndrome is a very rare multiple congenital anomaly–mental retardation syndrome caused by interstitial deletion of the distal portion of chromosome 11p13
a contiguous gene deletion syndrome, and WAGR is an acronym for the primary features:
- W for Wilms tumor
- A for aniridia
- G for genital anomalies
- R for mental retardation
- Wilms tumor and male genital anomalies are caused by deletion of the WT1 tumor-suppressor gene
- aniridia is caused by deletion of PAX6 ocular developmental gene
- mental retardation is presumed to be a consequence of deletion of multiple as yet unidentified genes in the region
- the majority of cases are identified by chromosome studies of children with sporadic aniridia and are due to de novo deletions of 11p13, although a few familial translocations are reported
- individuals with the WAGR syndrome have a high risk for developing Wilms tumor and late-onset renal failure, and should be monitored for these complications.
