Dyslipidemia is a risk factor for the development of atherosclerotic cardiovascular disease ().ASCVD includes coronary artery disease, cerebrovascular disease, and peripheral artery disease. Monogenic hypercholesterolemias have elevated low-density lipoprotein-cholesterol (LDL-C) levels and very high risk of premature atherosclerotic disease. As a result, an afflicted individual will have an excessive number of VLDL and triglycerides on a lipid profile.
