Following mismatch, a complex of proteins consisting of MLH1, MSH2, MSH6 and PMS2 translocate into the nucleus to signal recruitment of repair mechanisms. Flow cytometry-based, functional variant assays (FVAs), were developed to determine whether variants in these MMR repair genes and/or other related genes would augment the nuclear translocation of MLH1 and MSH2 and downstream nuclear phosphorylation of ATM and ATR in response to DNA mismatches. Each assay distinguished pathogenic variants in MMR repair genes (MLH1, MSH2, PMS2 and MSH6) from benign controls. The combination of multiple assays provided robust separation between heterozygous pathogenic variant carriers and benign controls. The ability to produce distinct molecular phenotypes by these assays suggest FVA assays of MMR pathways could be used to identify LS and associated risk of colon and other cancers and could act as an adjunct to MMR gene sequencing panels in categorizing variants."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and compositions for diagnosing and treating, germline mismatch repair deficiencies, lynch syndrome and assessing germline risks of cancer","description":"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.
