WebLynch syndrome (LS) is an autosomal dominant inherited disorder that primarily predisposes individuals to colorectal and endometrial cancer. It is associated with pathogenic variants in DNA mismatch repair (MMR) genes. In this study, we report the case of a 16-year-old boy who developed a precancero … WebMismatch-repair genes code for proteins that correct these naturally occurring spelling errors in the DNA. When these genes are mutated, mismatches (mistakes) in the DNA remain. If these mistakes happen in tumor suppressor genes or proto-oncogenes, this will lead to uncontrolled cell growth and tumor formation.
