What is "wagr syndrome"

n. aniridia-Wilms' tumor syndrome

WAGR syndrome is a rare genetic syndrome in which affected children are predisposed to develop Wilms tumour (a tumour of the kidneys), Aniridia (absence of the coloured part of the eye, the iris), Genitourinary anomalies, and Retardation. The G is sometimes instead given as "gonadoblastoma," since the genitourinary anomalies are tumours of the gonads ( testes or ovaries).

A subset of WAGR syndrome patients shows severe childhood obesity; the acronym WAGRO (O for obesity) has been used to describe this category.

The condition results from a deletion on chromosome 11 resulting in the loss of several genes. As such, it is one of the best studied examples of a condition caused by loss of neighbouring (contiguous) genes.
