Ordering Recommendation

Germline analysis of genes associated with high-risk hereditary colorectal cancer syndromes, including Lynch syndrome, familial adenomatous polyposis (FAP) or another APC-associated polyposis condition, and MUTYH-associated polyposis (MAP). Testing minors for adult-onset conditions is not recommended; testing will not be performed in minors without prior approval. For additional information, please contact an ARUP genetic counselor at 800-242-2787 ext. 2141.
