MUTYH-associated polyposis--from defect in base excision repair to clinical genetic testing.

Abstract excerpt

Established predisposition genes account for only a small proportion of familial colorectal cancer. Recently, it has been shown that germline mutations in MUTYH predispose to MUTYH-associated polyposis (MAP), an autosomal recessive disorder characterised by multiple colorectal adenomas and carcinomas. MUTYH functions as a base excision repair DNA glycosylase that excises adenines misincorporated opposite...
