Colorectal cancer (CRC) is a multifactorial disease and the etiology is complex. It involves dietary and other environmental factors, and in between 15 and 30% of cases, inherited genetic factors are significant. Approximately 5% of all colorectal cancers occur in the setting of a well described inherited syndrome like Lynch syndrome (Hereditary Non-Polyposis Colorectal Cancer; HNPCC), (Attenuated) Familial Adenomatous Polyposis ((A)FAP), and MUTYH-associated polyposis (MAP).

In families with clustering of CRC, but without evidence for one of the inherited syndromes, we deal with familial colorectal cancer. Subjects with one first degree relative (FDR) with CRC diagnosed at age >50 years, have a relative risk of developing CRC of 2–3. Subjects with two (or more) FDRs with CRC diagnosed at any age, or with one FDR with CRC
