Location [1]
Chromatin remodeling/DNA methylation
Protein [2]
DNA mismatch repair protein Msh2
Synonyms [1]

The mutS homolog 2 (MSH2) gene encodes a protein that functions in DNA-mismatch repair. Missense mutations, nonsense mutations, silent mutations, whole gene deletions, frameshift deletions and insertions, and in-frame deletions are observed in cancers such as endometrial cancer, intestinal cancer, and skin cancer.

MSH2 is altered in 1.97% of all cancers with non-small cell lung carcinoma, colorectal adenocarcinoma, malignant glioma, uterine corpus neoplasm, and breast carcinoma having the greatest prevalence of alterations [3].

MSH2 GENIE Cases - Top Diseases

The most common alterations in MSH2 are MSH2 Mutation (1.80%), MSH2 Mutation (germline) (1.80%), MSH2 Nonsense (0.29%), MSH2 Frameshift (0.18%), and MSH2 Amplification (0.06%) [3].
