WebWe examined the validity of immunohistochemistry for mismatch repair (MMR) proteins in colorectal cancer specimens to identify patients at risk for Lynch syndrome (hereditary nonpolyposis colorectal cancer) and patients with sporadic microsatellite instable colorectal cancer. This was assessed by ob … WebThe DNA mismatch repair ( MMR) system is coded by MMR genes and has a series of specific proteins. This system is able to keep DNA replication fidelity by maintaining genetic integrity and stability, and avoiding replication mutations. MMR consists of six core proteins, such as MSH2, MLH1, MSH3, MSH6, PMSH1, and PMSH2.
