This comprehensive Review describes the biological function of the mismatch repair (MMR) machinery, the genomic sequelae of defects in this machinery and the roles of hereditary or sporadic MMR deficiency in cancer predisposition and/or tumour development. The authors also discuss the clinical implications of MMR deficiency with a specific focus on diagnostic approaches, therapeutic strategies and mechanisms of resistance to immune-checkpoint inhibitors.
