Description : Autosomal recessive colorectal adenomatous polyposis is a disorder characterized by
adult-onset of multiple colorectal adenomas and adenomatous polyposis. Affected individuals
have a significantly increased risk of colorectal cancer (summary by Sieber et al.,
2003). Cheadle and Sampson (2003) reviewed the molecular pathology and biochemistry
of MYH colonic polyposis. See also familial adenomatous polyposis-1 (FAP1; 175100)
and attenuated FAP, similar disorders showing autosomal dominant inheritance and caused
by mutation in the APC gene (611731) on chromosome 5q.;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the MutY DNA glycosylase gene (MUTYH, 604933.0001);
Neoplasia : Increased risk of colorectal carcinoma;
