In the US, up to 30% of colon cancers exhibit familial clustering and 3–5% are associated with high-risk, inherited colon cancer syndromes. The authors of this Review discuss the clinical presentation and genetics of the major inherited colon cancer syndromes. Particular attention is paid to genetic testing, including when it is indicated, methods used and potential pitfalls. The role of the genetic counselor is also explored.
