Abstract

Although stroke is a common cause of death and a major cause of disability all over the world, genetic components of common forms of ischemic stroke are largely unknown. To identify susceptibility genes of atherothrombotic stroke, we performed a large case-control association study and a replication study in a total of 2775 cases with atherothrombotic stroke and 2839 controls. Through the analysis in 860 cases and 860 age-and sex-matched controls, we found that a single-nucleotide polymorphism (SNP), rs2280887, in the ARHGEF10 gene was significantly associated with atherothrombotic stroke even after the adjustment of multiple testing by a permutation test [unadjusted P = 1.2 × 10-6, odds ratio = 1.80, 95% confidence interval (CI) = 1.42-2.28]. This association was replicated in independent 1915 cases and 1979 controls. Subsequent fine mapping found another three SNPs which showed similar association due to strong linkage disequilibrium to rs2280887 (r2 > 0.95). In the functional analyses of these four highly associated SNPs, using luciferase assay and electrophoretic mobility shift assay we found that rs4376531 affected ARHGEF10 transcriptional activity due to the different Sp1-binding affinity. In small GTPase activity assay, we found that a gene product of ARHGEF10 specifically activated RhoA. A population-based cohort study revealed the subjects with rs4376531 CC or CG to increase the incidence of ischemic stroke (P = 0.033, hazard ratio = 1.79, 95% CI = 1.05-3.04). Our data suggest that the functional SNP of ARHGEF10 confers the susceptibility to atherothrombotic stroke.
