Microsatellite instability in saliva from patients with hereditary non-polyposis colon cancer and siblings carrying germline mismatch repair gene mutations.

Abstract excerpt

Microsatellites are short tandem repeats of deoxyribonucleic acid (DNA) sequences which are distributed throughout the genome. Tumors in patients with Lynch syndrome tend to accumulate mutations in microsatellites at a much higher rate than other sequences in the genome resulting in microsatellite instability (MSI). This is due to germline mutations in mismatch repair (MMR) genes. Using small pool-polymerase...
