Chromosome 10q25 polymorphism is associated with susceptibility to large artery atherosclerotic stroke
2019
Abstract Background and aims A recent genome-wide association study (GWAS) reported an association between a single nucleotide polymorphism (SNP) rs11196288 and risk of early-onset large artery atherosclerotic (LAA) stroke in European population. The interaction between genetic and environmental factors such as age has also received increasing attention. We performed this study to investigate the association between the rs11196288A > G polymorphism and LAA stroke risk in the Chinese Han population and test whether age interacts rs11196288 to influence LAA stroke risk. Methods Genotyping of rs11196288 was performed in 1066 LAA stroke patients and 1167 healthy controls. Multivariate logistic regression analyses were applied to assess the effect of the rs11196288A > G polymorphism on susceptibility and short-term outcome of LAA stroke. Nomograms were performed to estimate probability of risk for an individual patient. Results A significant decrement of LAA stroke risk was found in co-dominant (AG vs. AA, OR = 0.76, 95% CI = 0.64–0.91, P = 0.003; GG vs. AA, OR = 0.65, 95% CI = 0.50–0.85, P = 0.002), dominant (AG/GG vs. AA, OR = 0.74, 95% CI = 0.62–0.87, P P = 0.028) of rs11196288. However, the interaction between age and genotypes of rs11196288 was not statistically significant, and no significant association was observed between the rs11196288A > G polymorphism and short-term outcome of LAA stroke ( P > 0.05). Conclusions In the southeastern Chinese population, the rs11196288A > G polymorphism is associated with decreased risk of LAA stroke.
