In randomized trials, statins reduce plasma levels of C-reactive protein (CRP) and low-density lipoprotein cholesterol (LDL-C), and the magnitude of event reduction relates to on-treatment levels of both. However, whether different mechanisms underlie statin-induced CRP and LDL-C reduction is unknown.


We performed a study to evaluate potential genetic determinants of CRP response using genome-wide genetic data from a total of 6766 participants of European ancestry randomly allocated to 20 mg/d of rosuvastatin or placebo in the JUPITER trial. Among 3386 rosuvastatin-allocated individuals, both CRP and LDL-C levels were reduced by 50% after 12 months of therapy (P<0.001 for both) and essentially uncorrelated (r(2)<0.03). No variants in the 3 genes (ABCG2, LPA, and APOE) that previously showed genome-wide association with LDL-C reduction in this cohort and none of the candidate single-nucleotide polymorphisms associated with LDL-C reduction were associated with rosuvastatin-induced CRP change after multiple testing correction. Among candidate single-nucleotide polymorphisms selected from prior genetic analyses of baseline CRP, CRP reduction was associated with rs2794520 in CRP (mean, -3.5% [SE, 2.0%] change in CRP per minor allele; P=6.4×10(-4)) and with rs2847281 in PTPN2 (mean, 3.7% [SE, 1.9%] change in CRP per minor allele; P=7.4×10(-4)). These associations remained significant after multiple testing correction but were not significant in a formal test of interaction. Neither variant was associated with rosuvastatin-induced LDL-C reduction or with CRP reduction among 3380 placebo-allocated JUPITER participants.


The genetic determinants of rosuvastatin-induced CRP reduction differ from, and are largely independent of, the major pharmacogenetic determinants of rosuvastatin-induced LDL-C reduction. This supports the hypothesis that differing pathways may mediate the anti-inflammatory and lipid-lowering properties of statin therapy.
