Variants with large effects on blood lipids and the role of cholesterol and triglycerides in coronary disease

Kari Stefansson and colleagues report discovery of 13 variants with large effects on non-HDL cholesterol, LDL cholesterol, HDL cholesterol or triglyceride lipid fractions. They further show that, among these lipid fractions, the non-HDL cholesterol genetic risk score associates most strongly with coronary disease and confers risk beyond that of LDL cholesterol and that, after accounting for non-HDL cholesterol, neither HDL cholesterol nor triglyceride genetic risk scores associate with coronary disease.
