Deletions Account for 17% of Pathogenic Germline Alterations in <i>MLH1</i> and <i>MSH2</i> in Hereditary Nonpolyposis Colorectal Cancer (HNPCC) Families
1 Jun 2005
Abstract excerpt
Hereditary nonpolyposis colorectal cancer (HNPCC) is due to defects in DNA mismatch repair (MMR) genes MSH2, MLH1, MSH6, and to a lesser extent PMS2. Of 466 suspected HNPCC families, we defined 54 index patients with either tumors of high microsatellite instability (MSI-H) and/or loss of expression for either MLH1, MSH2, and/or MSH6, but without a detectable pathogenic point mutation in these genes. This study...
