MYH-associated polyposis is an inherited condition characterized by the development of multiple adenomatous colon polyps and an increased risk of colorectal cancer.[1][2] This condition, a milder form of familial adenomatous polyposis (FAP), is sometimes called autosomal recessive familial adenomatous polyposis because it is inherited in an autosomal recessive manner. People with this condition have fewer polyps than those with the classic type of FAP; fewer than 100 polyps typically develop, rather than hundreds or thousands.[2] They may also be at increased risk for upper gastrointestinal polyps.[1] MYH-associated polyposis is caused by mutations in the MYH gene.[1][2]
