|---|---|
| Other names | PPAP |
| Specialty | Medical genetics, gastroenterology |
| Symptoms | Asymptomatic, often develop multiple colorectal adenomas |

Polymerase proofreading-associated polyposis (PPAP) is an autosomal dominant hereditary cancer syndrome, which is characterized by numerous polyps in the colon and an increased risk of colorectal cancer.[1] It is caused by germline mutations in DNA polymerase ε (POLE) and δ (POLD1).[1] Affected individuals develop numerous polyps called colorectal adenomas. Compared with other polyposis syndromes, Polymerase proofreading-associated polyposis is rare. Genetic testing can help exclude similar syndromes, such as Familial adenomatous polyposis and MUTYH-associated polyposis. Endometrial cancer, duodenal polyps and duodenal cancer may also occur.[2]
Genetics
PPAP is an autosomal dominant syndrome caused by germline mutations in DNA polymerase ε (POLE) and δ (POLD1).[1] The penetrance of the condition appears high.[3]
