Influence of ZFHX3 Polymorphisms on the Risk of Ischemic Stroke in Chinese Han Population

The association of ZFHX3 gene polymorphisms with ischemia stroke (IS) susceptibility has been clarified in Europeans, but not in the Chinese Han population. To assess the effect of ZFHX3 polymorphisms on IS risk, rs7193343, rs879324, and rs12932445 were selected and genotyped using the Agena MassARRAY platform in 694 patients and 687 healthy controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by logistic regression model adjusted for age, sex, smoking, and drinking status. The potentially influential factors for IS risk were analyzed using multifactor dimension reduction (MDR) software v3.0.2 and least absolute shrinkage and selection operator (LASSO) logistic regression. Our results displayed that rs879324 (p = 0.011, OR = 0.81) and rs12932445 (p = 0.012, OR = 0.81) were protective factors for IS in the Chinese Han population. Specifically, rs879324 had a lower susceptibility to IS in subjects aged <= 64 years, non-smokers, and non-drinkers (p < 0.05). Furthermore, rs12932445 was associated with a reduced risk of IS in people aged > 64 years, females, non-smokers, and non-drinkers (p < 0.05). MDR and LASSO analyses revealed that rs879324 was the most influential factor for IS risk. These findings suggested that ZFHX3 variants may be biomarkers in IS occurrence in the Chinese Han population, which may provide a new insight into the etiology of IS.
