Highly conserved mismatch repair (MMR) systems have been identified in organisms ranging from bacteria to humans that recognize and repair base pair and small insertion/deletion mismatches that arise as the result of DNA replication errors, DNA damage, and genetic recombination. In humans, mutations in MMR genes have been correlated to both an increased mutation rate and a predisposition to a hereditary form of colorectal cancer (HNPCC). HNPCC has a high cure rate if detected early, underscoring the importance of obtaining new mechanistic understandings of mismatch repair and new diagnostic tools.
