Description : Familial adenomatous polyposis is an autosomal dominant disorder characterized by
predisposition to cancer. Affected individuals usually develop hundreds to thousands
of adenomatous polyps of the colon and rectum, a small proportion of which will progress
to colorectal carcinoma if not surgically treated. Gardner syndrome is a variant of
FAP in which desmoid tumors, osteomas, and other neoplasms occur together with multiple
adenomas of the colon and rectum (Nishisho et al., 1991). Rustgi (2007) reviewed the
genetics of hereditary colon cancer, including APC. See also FAP2 (608456), a similar
disorder showing autosomal recessive inheritance and caused by mutation in the MUTYH
gene (604933) on chromosome 1p34.;
Inheritance : Autosomal dominant;
Molecular basis : Caused by mutation in the adenomatous polyposis coli gene (APC, 611731.0001);
Neoplasia : Adrenal carcinoma; Thyroid papillary carcinoma; Periampullary carcinoma; Fibrosarcoma; Colon carcinoma; Gastric adenocarcinoma; Medulloblastoma; Hepatoblastoma; Small intestine carcinoid; Desmoid tumor; Astrocytoma;
