Abstract:
Objective To verify the correlation between rs17118 polymorphism of xyluloknase homolog (XYLB) gene and risk of ischemic stroke in a Chinese Han population.Methods A case-control study design was used.The case group was the patients with first-ever ischemic stroke and the control group was the healthy subjects from hospital physical examination.Taqman probe fluorescence quantitative polymerase chain reaction technique was used to detect the genotype distribution of rs17118 C/A polymorphisms.Results A total of 475 patients with ischemic stroke and 483 controls were enrolled in the study.The proportion of hypertension (67.9％ vs.22.2％;x2 =292.982,P ＜ 0.001) and diabetes (24.2％ vs.7.3％;x2 =25.864,P ＜ 0.001),as well as the levels of triacylglycerol (1.649 ± 1.126 mmol/L vs.1.157 ±1.480 mmol/L;t=3.592,P＜0.001),and low-density lipoprotein cholesterol (3.499 ± 1.163 mmol/L vs.3.105 ± 0.627 mmol/L;t =-6.227,P ＜ 0.001) in the case group were significantly higher than those in the control group,but the total cholesterol level was significantly lower than that in the control group (5.144 ± 1.296 mmol/L vs.5.491 ± 1.335 mmol/L;t =4.650,P ＜ 0.001).The AA genotyp e (11.4％ vs.7.5 ％;x2 =6.136,P =0.016) and A allele (32.3 ％ vs.26.4％;x2 =8.093,P =0.005) frequencies in the case group were significantly higher than those in the control group.Multivariatelogistic regression analysis showed that after adjusting for traditional risk factors,the risk of ischemic stroke in AA genotype carriers was 1.97 times of the CC genotype carriers (odds ratio 1.971,95％ confidence interval 1.040-3.736,P=0.038).Conclusions The rsl7118C/A polymorphism of XYLB gene may be associated with the risk of ischemic stroke in the Chinese Han population.
