For some rare cancers, the risk of a family cancer syndrome is relatively high with even one case. The age of the person when the cancer was diagnosed is also important. For example, colon cancer usually is rare in people younger than 30. Having close relatives under 30 with colon cancer could be a sign of an inherited cancer syndrome. Only a small percentage of colon cancers are linked to inherited genes.

A proline to leucine change due to a C to T transition in codon 622 of hMSH2 has been identified in a large HNPCC family of over 240 individuals.

Colorectal cancers among patients with a familial risk of this disorder account for hereditary colorectal cancer, familial adenomatous polyposis and hereditary

Hereditary colorectal cancer syndromes include Lynch syndrome and several polyposis syndromes (familial adenomatous polyposis, MUTYH-associated polyposis, juvenile polyposis syndrome, Peutz-Jeghers syndrome, and serrated polyposis syndrome). Learn about the genetics, clinical manifestations, management, and psychosocial aspects of these and other hereditary colon cancer syndromes in this Hereditary colorectal cancer is expressed mainly in two ways. One type, familial polyposis (FAP), is characterized by formation of a large number of polyps in the colon. The other, and considerably more common, type is Hereditary Non-Polyposis Colorectal Cancer (HNPCC). This disorder is characterized by isolated polyps, If you have a family history of colorectal polyps or cancer, you have a higher risk of getting colorectal cancer yourself.
