WebDescription. MLH1 promoter methylation assay is useful for the evaluation of hereditary colorectal cancer and tumors that have MLH1 and PMS2 loss by immunohistochemistry (IHC). Approximately 85% of tumors that have IHC loss of MLH1 and PMS2 will have MLH1 promoter methylation, the majority of which is somatic in origin. WebDNA damage, due to environmental factors and normal metabolic processes inside the cell, occurs at a rate of 10,000 to 1,000,000 molecular lesions per cell per day. While this constitutes at most only 0.0003125% of the human genome's approximately 3.2 billion bases, unrepaired lesions in critical genes (such as tumor suppressor genes) can …
