Patent number: 11981959Abstract: Heritable pathogenic variants in the mismatch repair (MMR) pathway, also known as Lynch Syndrome (LS), can lead to the development of colon cancer and other cancers. Following mismatch, a complex of proteins consisting of MLH1, MSH2, MSH6 and PMS2 translocate into the nucleus to signal recruitment of repair mechanisms.
