The genes involved in the 11p13 deletion and some of the phenotypes described in the WAGR population overlap with other disorders characterized by deletions or mutations of PAX6 (aniridia syndrome/spectrum, OMIM #106210) and WT1 (Denys-Drash syndrome/spectrum, OMIM# 194080; and Frasier syndrome/spectrum, OMIM# 136680); among others. This evidence concerns the gene PAX6 and Frasier syndrome.
