DESCRIPTION:

List of positional candidate genes after correcting for multiple testing and controlling the false discovery rate from genome wide association studies (GWAS) retrieved from the NHGRI-EBI Catalog of published genome-wide association studies (http://www.ebi.ac.uk/gwas/). The disease/trait examined in this study, as reported by the authors, was C-reactive protein. The EFO term C-reactive protein measurement was annotated to this set after curation by NHGRI-EBI. Intergenic SNPS were mapped to both the upstream and downstream gene. P-value uploaded. This gene set was generated using gwas2gs v. 0.1.8 and the GWAS Catalog v. 1.0.1.

ABSTRACT:

C-reactive protein (CRP) is a hallmark acute-phase reactant and is widely used as a blood marker for inflammation. Substantial roles of serum CRP levels in the pathogenesis of diseases have been suggested, and investigation of the mechanisms that regulate serum CRP levels would have a substantial clinical impact. Here, through genome-wide association and replication studies performed using 12 854 Japanese subjects, we identified a significant association between serum CRP levels and a single nucleotide polymorphism in the promoter region of interleukin-6 (IL6) (rs2097677, P = 4.1 × 10(-11)), a typical pleiotropic pro-inflammatory cytokine. Our study also replicated the associations in the CRP (rs3093059, P = 3.5 × 10(-21)) and HNF1A loci (rs7310409, P = 2.7 × 10(-8)). Pleiotropic association analysis with hematological and biochemical traits using 30 466 Japanese subjects demonstrated that the CRP-increasing allele of rs2097677 in the IL6 locus was significantly associated with an increased white blood cell count, platelet count and serum globulin and a decreased mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration (P < 5.0 × 10(-4)), although no pleiotropic association was observed in the CRP or HNF1A locus (α = 0.01). Our study demonstrated the pivotal role of the IL6 locus in the regulation of serum CRP levels and inflammatory pathways. PUBMED: 21196492
