Defective Mismatch Repair, Microsatellite Mutation Bias, and Variability in Clinical Cancer Phenotypes

Abstract excerpt

Microsatellite instability is associated with 10% to 15% of colorectal, endometrial, ovarian, and gastric cancers, and has long been used as a diagnostic tool for hereditary nonpolyposis colorectal carcinoma-related cancers. Tumor-specific length alterations within microsatellites are generally accepted to be a consequence of strand slippage events during DNA replication, which are uncorrected due to a defective...
