MutS homolog 3 (MSH3) is a gene that encodes a protein that is a component of MutS beta - a post-replicative DNA mismatch repair system. The protein functions in DNA mismatch repair. Missense mutations, nonsense mutations, silent mutations, frameshift deletions and insertions, and in-frame deletions are observed in cancers such as intestinal cancer, skin cancer, and stomach cancer.

MSH3 is altered in 2.28% of all cancers with colon adenocarcinoma, endometrial endometrioid adenocarcinoma, lung adenocarcinoma, prostate adenocarcinoma, and conventional glioblastoma multiforme having the greatest prevalence of alterations [3].

MSH3 GENIE Cases - Top Diseases

The most common alterations in MSH3 are MSH3 Mutation (1.32%), MSH3 A60_A62dup (2.37%), MSH3 Loss (0.11%), MSH3 A61_P63dup (0.32%), and MSH3 Amplification (0.02%) [3].
