Clinical Management and Tumor Surveillance Recommendations of Inherited Mismatch Repair Deficiency in Childhood

Abstract excerpt

Abstract Replication proofreading is crucial to avoid mutation accumulation in dividing cells. In humans, proofreading and replication repair is maintained by the exonuclease domains of DNA polymerases and the mismatch repair system. Individuals harboring germline mutations in genes involved in this process are at increased risk of early cancers from multiple organs. Biallelic mutations in any of the four...
