MSH6 and endometrial carcinoma: The presentation of some small short-tandem repeats such as mononucleotide repeats located within the coding sequence of important genes for example, transforming growth factor β receptor type II (TGF-βRII), BAX, insulin-like growth factor II receptor (IGFIIR), MSH3, MSH6, caspase-5, and PTEN may promote MSI-positive endometrial carcinoma [8, 9].
