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 Hemostatic factors and hematological phenotypes. The EFO term protein S measurement, hematological 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:

Deficiencies of antithrombin (AT), protein C (PC) and protein S (PS) or an impaired PC anticoagulant pathway increase the risk of venous thrombosis (VT). By conducting a genome-wide association study (GWAS) on two independent samples of VT patients totalling 951 subjects typed for 472 173 single nucleotide polymorphisms (SNPs), we observed that common SNPs explain 21% and 27% of the genetic variance of plasma AT and PS levels, even though no SNP reached genome-wide significance. For PC, we showed that two PROCR SNPs, rs867186 (Ser219Gly) and rs6060278, additionally explained c. 20% (P = 1·19 × 10(-31)) of the variance of plasma PC levels. We also observed that c. 40% of the remaining genetic variance of PC levels could be due to yet unidentified common SNPs. The PROCR locus was also found to explain c. 8% (P < 10(-10)) of agkistrodon contortrix venom (ACV) (exploring the PC pathway) variability which was under the main control of the F5 and F2 loci that further explained about 40% and 10%, respectively. We presented here the first GWAS for plasma AT and free-PS levels and ACV in Caucasian samples. We identified three independent loci associated with ACV (F2, F5 and PROCR) and replicated two independent effects on plasma PC levels at the PROCR locus. PUBMED: 22443383
