    Abstract:
    Adiponectin is inversely associated with the risk of ischemic stroke through its anti-inflammatory and anti-atherogenic effects. Genetic variations in the adiponectin gene (ADIPOQ) have been shown to be associated with the risk of ischemic stroke in Caucasians and Japanese populations. However, it was unknown whether variations in the ADIPOQ gene were associated with the risk of ischemic stroke in Chinese population. A case-control study was performed among 302 patients with ischemic stroke and 338 unrelated controls in a Chinese Han population. The single-nucleotide polymorphisms (SNPs) rs266729 (-11377C/G), rs2241766 (+45T/G), rs1501299 (+276G/T) in the ADIPOQ gene were genotyped by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The frequencies of GG genotype and G allele of rs266729 in the patients with ischemic stroke were significantly higher than those in the controls (P = 0.034, P = 0.010, respectively). In univariate logistic analysis, compared with CC genotype, GG genotype of rs266729 increased the risk of ischemic stroke (odds ratio (OR) = 2.062, 95% confidence interval (CI) = 1.145-3.715, P = 0.016). After adjustment for potential risk factors by the multivariate logistic analysis, rs266729 remained positive correlation with ischemic stroke (OR = 2.165; 95% CI = 1.116-4.197, P = 0.022). However, no significant association was observed among rs2241766, rs1501299 and ischemic stroke. In addition, no significant difference was found in haplotype frequencies between the patients with ischemic stroke and control subjects. The present study demonstrated that the promoter polymorphism rs266729 of the ADIPOQ gene was associated with an increased risk of ischemic stroke in the Chinese Han population.
