Mismatch repair in hereditary nonpolyposis colorectal cancer

Hereditary nonpolyposis colorectal cancer as a eolorectal cancer is of most hereditary characters.With developing of the molecular genetics on detection technology,mismatch repair gene has already been detected by multi-approach,and been applied to screen hereditary nonpolyposis eolorectal cancer patients.In this artical,we mainly discuss the correlated study progression between hereditary nonpolyposis eolorectal cancer and several mismatch repair genes such as MSH2,MLH1,MSH6,PMS1,PMS2,MLH3 and EXO1. Key words: mismatch repair;  hereditary nonpolyposis eolorectal cancer;  gene
