Familial adenomatous polyposis-4 is an autosomal recessive tumor predisposition syndrome characterized by the development of multiple colonic adenomas in adulthood, often with progression to colorectal cancer. Proliferative lesions in other tissues may also occur (summary by Adam et al., 2016).
For a discussion of genetic heterogeneity of familial adenomatous polyposis, see FAP1 (175100). [from OMIM]
