Abstract The past decade has witnessed substantial growth in our knowledge of the genes and loci that are altered in Wilms tumor. Although Wilms tumor was one of the original paradigms of Knudson's two-hit model of cancer formation, it has become apparent that several genetic events contribute to Wilms tumorigenesis. Recent research has identified targets and regulators of the first Wilms tumor gene, WT1, has uncovered several candidate genes at the second Wilms tumor locus, WT2, and has identified two familial Wilms tumor loci, FWT1 and FWT2. The recent discovery of activating beta-catenin mutations in some Wilms tumors has also implicated the Wnt signaling pathway in this neoplasm. Recurrent abnormalities of other loci, including 16q, 1p, and 7p, have indicated that these sites may harbor Wilms tumor genes. An enhanced understanding of these and other genetic lesions will provide the foundation for novel targeted Wilms tumor therapies.
