The single nucleotide polymorphisms (SNPs) apolipoprotein E (APOE) epsilon3/epsilon2/epsilon4, cholesteryl ester transfer protein (CETP) TaqIB, and apolipoprotein C3 (APOC3) -482 C>T have been associated with an atherogenic lipid profile and, in some studies, with increased cardiovascular risk. However, no data exist on their combined impact on atherosclerotic disease. We therefore ...
