In microsatellite stable tumors, homozygous carriers of the G39Epolymorphism had an increased risk of CIMP+ colon cancer (odds ratio (OR) 2.2, 95% confidence interval (CI) 1.1, 4.2) and BRAF V600E mutation (OR 3.1, 95% CI 1.01, 9.7) in a case-control comparison.
A study was conducted to examine whether MLH1 (-93G>A and Ile219Val) and MSH6 (Gly39Glu) polymorphisms were associated with risk of colon cancer in data from 1609 colon cancer cases and 1972 controls.
