DARK STUDY "DysbetalipoproteinemiA and atheRoma Risk" (DARK)

January 25, 2013 updated by: Hospices Civils de Lyon

Dysbetalipoproteinemia and Atheroma Risk : Assessment of Cardiovascular Risk in Dysbetalipoproteinemic Patients

Dysbetalipoproteinemia (type III, Fredrickson's classification) is a rare metabolic disorder. It results from a defect in the clearance of VLDL and chylomicron remnants due to homozygous APOE2 variants or heterozygous APOE mutations, and there is an elevated plasma cholesterol and triglycerides.

As a consequence of the derangements in lipoprotein metabolism, dysbetalipoproteinemia predispose to the premature development of atherosclerosis.

However among this population there is heterogeneity in development of cardiovascular complications and the determinants remain unclear actually.

The aim of the investigators study is to evaluate the intensity of clinical atherosclerosis, and identify its determinants.
