Familial Adenomatous Polyposis 1; Fap1

Description

Familial adenomatous polyposis-1 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. Genetic Heterogeneity of Familial Adenomatous PolyposisSee also autosomal recessive FAP2 (OMIM ), caused by mutation in the MUTYH gene (OMIM ) on chromosome 1p34; autosomal recessive FAP3 (OMIM ), caused by mutation in the NTHL1 gene (OMIM ) on chromosome 16p13; and autosomal recessive FAP4 (OMIM ), caused by mutation in the MSH3 gene (OMIM ) on chromosome 5q11.
