Germline mutation in the adenomatous polyposis coli (APC) gene causes the majority (80%) of familial adenomatous polyposis (FAP), an autosomal dominantly inherited form of colorectal cancer (CRC). Mutation in 5'end of exon 9 of APC usually results in an attenuated form of FAP (aFAP), characterized by later age of onset and fewer polyps.
