The E‐selectin gene, a member of the selectin superfamily of adhesion molecules, plays an important role in the pathogenesis of thrombovascular diseases. The present study was designed to investigate the potential relationship between E‐selectin gene polymorphisms and ischemic stroke in a Chinese Han population. Three hundred fourteen ischemic stroke patients and 389 unrelated healthy controls were recruited for the study. Three single‐nucleotide polymorphisms (SNPs)—rs1805193(G98T), rs5361(A561C), and rs5355(C1839T)—in the exon region of the E‐selectin gene, were genotyped using a Multiplex SNaPshot sequencing assay. The data showed that the genotype and allele frequencies of G98T and C1839T SNP were similar in both ischemic stroke patients and the controls. In contrast, the frequency of both the AC genotype and the C allele of A561C was significantly higher in ischemic stroke patients than in healthy controls ( P = 0.001, P < 0.001, respectively). After adjusting for other risk factors (such as hypertension, diabetes, tobacco smoking, and alcohol consumption), the E‐selectin gene AC genotype and C allele of A561C were still associated with a risk of ischemic stroke (odds ratio [OR] = 2.73, 95% confidence interval (CI): 1.29–5.76, P = 0.008; OR = 2.80, 95% CI: 1.58–4.94, P < 0.001, respectively). Our current study demonstrates that the E‐selectin SNP A561C is associated with increased risk for the development of ischemic stroke in this subset of the Han Chinese population. © 2012 Wiley Periodicals, Inc.
