Studying Cancer Families to Identify Kidney Cancer Genes

Abstract

We studied families with multiple members affected with renal cancer to delineate clinically distinct forms of inherited renal cancer, and to identify and characterize the genes responsible for these disorders. Today, cancer geneticists recognize seven clinically distinct, inherited forms of epithelial renal cancer; genes responsible for five inherited predispositions have been found. Positional cloning efforts for one kidney cancer gene are nearing completion. These discoveries will provide diagnostic tests for these diseases, a foundation for studies of the relationship between genotype and phenotype, and a basis for studies of the pathophysiology of the diverse types of epithelial renal cancer.
