Further studies are necessary.
Approximately 500,000 Ashkenazi Jews may have mutations in this gene, and the majority of these mutations occur at a single location in those Ashkenazi Jews carrying mutations in this gene. A mutation in the APC gene places one at increased risk of developing colon cancer, and some have suggested that Ashkenazi Jewish patients with a familial history of colon cancer be tested for this specific mutation. When such a test is positive, regular colonoscopic examination, usually from age 35 onward, is imperative. In general, approximately 130,000 cases of colon cancer are discovered in the U.S.A. each year. As yet, the majority of the genes involved in these hereditary relationships have not been well characterized.
