Large-scale mendelian randomization meta-analysis (n=654,783) compared associations of triglyceride-lowering variants in the lipoprotein lipase (LPL) gene and LDL-C–lowering variants in the LDL receptor gene (LDLR) with the risk of cardiovascular disease per unit change in ApoB.
Differences in plasma triglyceride, LDL-C, and ApoB levels associated with the LPL and LDLR genetic scores. Triglyceride-lowering LPL variants and LDL-C–lowering LDLR variants were associated with similar lower risk of CHD per unit difference in ApoB. Therefore, the clinical benefit of lowering triglyceride and LDL-C levels may be proportional to the absolute change in ApoB.
