also called FAP. An inherited condition that puts a person at risk for getting colorectal cancer when they are young. People with this syndrome develop many polyps in the colon and rectum as well as tumors in other parts of the body. Usually one or more of these polyps becomes cancer if it is not removed. FAP is caused by changes in the APC gene. See also APC gene, colon, gastrointestinal tract, polyp, rectum, tumor.
