Effective date
Not stated in the notice
Identified
Jun 20, 2026

Summary

The use of genotyping for 9p21 single nucleotide polymorphisms is considered investigational, including identification of patients who may be at increased risk of cardiovascular disease or its manifestations, or identification of patients who may be at increased risk for aneurysmal disease. The listed manifestations are myocardial infarction, ischemic stroke, peripheral arterial disease and coronary artery calcification, and the listed aneurysmal diseases are abdominal aortic aneurysms, intracranial aneurysms and polypoidal choroidal vasculopathy. No manufactured test kit for 9p21 genotyping has been reviewed by the FDA, and 9p21 genotyping tests are laboratory-developed tests offered by clinical laboratories licensed under CLIA for high-complexity testing.
