Wilms' tumor and gonadal dysgenesis in a child with the 2q37.1 deletion syndrome.

Here we report Wilms' tumor, gonadal dysgenesis and a bifid uterus in an 18-month-old female with a terminal deletion of the long arm of chromosome 2 [46,XX,del(2)(q37.1)]. Since Wilms' tumor has been previously reported in the 2q37 deletion syndrome, the present observation raises the question of whether a tumor susceptibility gene maps to chromosome 2q37 and suggests giving consideration to the possible occurrence of Wilms' tumor in the course of disease.
