Table 4. Absolute Risks of Colorectal Cancer for Mutation Carriers in Hereditary Colorectal Cancer Syndromes
| Syndrome | Absolute Risk in Mutation Carriers |
| FAP | 90% by age 45 y [1] |
| Attenuated FAP | 69% by age 80 y [2] |
| Lynch | 40% to 80% by age 75 ya [3,4] |
| MYH-associated polyposis | 35% to 53% [5] |
| Peutz-Jeghers | 39% by age 70 y [6] |
| Juvenile polyposis | 17% to 68% by age 60 y [7,8] |
| FAP = familial adenomatous polyposis. | |
| aRefer to the Lynch syndrome (LS) section of this summary for a full discussion of risk. |
