Are there genetic markers for colon cancer?

Genetic tests can help show if members of certain families have inherited a high risk of colorectal cancer due to inherited cancer syndromes such as Lynch syndrome (also known as hereditary non-polyposis colorectal cancer, or HNPCC) or familial adenomatous polyposis (FAP).

What are DNA markers for colon cancer?
