Objective: To assess the association of polymorphisms of rs3819024 and rs8193037 loci in the promoter region of IL-17A gene with the risk of ischemic stroke (IS) among ethnic Han Chinese from Guangxi.
Methods: The polymorphisms of rs3819024 and rs8193037 loci were detected by a SNaPshot assay and DNA sequencing among 392 IS patients and 443 healthy controls with matched age and gender.
Results: The genotypes, dominant model, recessive model, and alleles of rs3819024 polymorphisms showed no significant difference between the two groups, with the P values calculated as 0.150, 0.227, 0.125, 0.594 and 0.202, respectively, and OR (95% CI) as 1.27(0.92-1.74), 1.28(0.86-1.91), 1.27(0.94-1.72), 1.10(0.78-1.54), and 1.13(0.94-1.38), respectively. The genotypes, dominant model, recessive model, and alleles of rs8193037 polymorphisms also showed no significant difference between the two groups, with the P values calculated as 0.722, 0.352, 0.863, 0.345 and 0.969, respectively, and OR (95% CI) as 0.94(0.65-1.35), 2.25(0.41-12.35), 0.97(0.68-1.38), 2.27(0.41-12.48), and 1.01(0.72-1.40), respectively.
Conclusion: Polymorphisms of the rs3819024 and rs8193037 loci of the IL-17A gene are not associated with the susceptibility to IS among ethnic Han Chinese from Guangxi.
