<unk>  is a rare genetic syndrome in which affected children are predisposed to develop Wilms tumor (a tumor of the kidneys), Aniridia (absence of the colored part of the eye, the iris), Genitourinary anomalies, and mental Retardation.  The G is sometimes instead given as "gonadoblastoma," since the genitourinary anomalies are tumors of the gonads (testes or ovaries).
A subset of<unk>  patients shows severe childhood obesity; the acronym<unk> O (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.
