Multiple epithelial and nonepithelial tumors in hereditary nonpolyposis colorectal cancer: characterization of germline and somatic mutations of the MSH2 gene and heterogeneity of replication error phenotypes.

Abstract excerpt

Hereditary nonpolyposis colorectal cancer (HNPCC) is an autosomal inherited cancer syndrome characterized by germline plus somatic mutations of DNA mismatch repair genes and familial clustering of cancers of colorectum and other visceral organs. So far, to our knowledge, there has been no proof of nonepithelial tumors in association with HNPCC. Here we report on a MSH2 frameshift HNPCC family with a carrier found...
