Abstract excerpt
Hereditary nonpolyposis colorectal cancer (HNPCC) is a dominantly inherited cancer syndrome. Germline mutations in five different mismatch repair (MMR) genes, MSH2, MSH6, MLH1, MLH3, and PMS2 are linked to HNPCC. Here, we describe two colon cancer families in which the index patients carry missense mutations in both MSH2 and MSH6. The MSH2 mutation, I145M, is the same in both families, whereas the MSH6 mutations...
