摘要: Publisher Summary This chapter describes recent advances in the study of DNA mismatch repair (MMR) genes, with emphasis on mutations predisposing to hereditary nonpolyposis colorectal cancer (HNPCC), their phenotypic effects, and scientific clinical implications these findings. The main forms (CRC) are familial adenomatous polyposis (FAP) HNPCC. diagnosis HNPCC was mainly based family history. kindreds commonly defined as those which at least three relatives two generations have CRC, one being a first-degree relative other and, furthermore, diagnosed less than 50 years age. A definitive is gene analyses. normal function proteins encoded by genes participate (MMR). syndrome sometimes divided into Lynch syndromes I II absence or presence, respectively, extracolonic cancer. CRC develop via precancerous growth, adenoma. systematic search through entire genome using highly informative short tandem repeat (microsatellite) markers resulted identification first susceptibility locus chromosome 2p linkage analysis.
