However, compared with the mutations rates for colorectal cancers associated with Lynch syndrome in 44 Korean individuals, wherein only four patients with endometrial cancers were included and reported mutation rates of 70.5, 22.7, and 6.8% in MLH1, MSH2, and MSH6, respectively [1], the MLH1 mutation rate is greater in colon cancer than in endometrial cancer associated with Lynch syndrome. Here, MLH1 is linked to malignant colon neoplasm.
