DNA mismatch repair (MMR) maintains genome stability primarily by correcting replication-associated mismatches. Defects in MMR lead to several human cancers characterized by frequent alterations in simple repetitive DNA sequences, a phenomenon called microsatellite instability (MSI). In most MSI-positive cancers, genetic
