The MMR process relies on four main proteins: MLH1, MSH2, MSH6, and PMS2 that work together to repair mistakes in the DNA. In some cancer patients, the MMR process works well. For these people, the cancer cells are proficient in mismatch repair (pMMR) and their tumor cells have the same number of repeats as in their healthy cells.
