MMR (Mismatch Repair) Genes

Mismatch Repair (MMR) genes are crucial for maintaining the accuracy of our DNA. They help fix errors that occur when DNA is copied during cell division; these errors can lead to mutations, which might cause diseases like cancer. If MMR genes aren’t functioning properly, these errors can accumulate, increasing cancer risk. They play a significant role in certain types of hereditary cancers, such as Lynch syndrome. Overall, MMR genes are essential for genetic stability and preventing the development of tumors by correcting mismatches in the DNA structure.
