Colorectal cancer showing somatic MLH1 methylation tends to occur at relatively advanced ages, is more common in women, is often located in the right colon (as also shown in this study), displays the somatic activating BRAF V600E mutation and occurs in sporadic tumours instead of in the inherited form of CRC, like LS [24,50,51]. This evidence concerns the gene MLH1 and colorectal cancer.
