For patients assessed to be at a high risk for contracting colorectal cancer, this chart outlines appropriate screening and follow-up sequences.
Hereditary Gastrointestinal Polyposis and Nonpolyposis Syndromes
Condition | Genes (Inheritance) | Key Clinical Features |
---|---|---|
Polyposis syndrome | | |
Familial adenomatous polyposis (FAP) | APC (AD) | 100s–1,000s of colonic adenomatous polyps Duodenal/periampullary adenomas Onset in teenage years Prophylactic proctocolectomy is standard |
Attenuated FAP | PC (AD) | <100 colonic adenomas, onset in adulthood |
MYH-associated polyposis | MUTYH (AR) | Wide range in number of colon adenomas (few–1,000s) |
Polymerase proofreading-associated polyposis | POLD1, POLE (AD) | 5–100 colon adenomas; Increased risk of endometrial cancer |

Juvenile polyposis | BMPR1A, SMAD4 (AD) | Multiple juvenile polyps Increased risk of colon cancer Hereditary hemorrhagic telangiectasia phenotype in some SMAD4 families |
Serrated polyposis | Unknown | Multiple sessile serrated adenomas (at least five serrated polyps proximal to sigmoid colon, two of which are >1cm in size) |
Nonpolyposis syndrome | | |
Lynch | MLH1, MSH2, MSH6, PMS2, EPCAM (AD) | High risk of colon and endometrial cancer Absence of multiple polyps Most common hereditary colon cancer syndrome |
