Abstract:
Objective To investigate the correlation between histone deacetylase 9 gene ( HDAC9 ) single nucleotide polymorphisms and ischemic stroke ( IS) subtypes. Methods A total of 202 patients with IS were enrolled prospectively. According to the Trial of Org 10172 in Acute Stroke Treatment ( TOAST) classification,the patients with IS were divided into large artery atherosclerotic stroke group (LAA,n=149) and the small-artery occlusive stroke group (SAO,n=53). A total of 201 age- and sex-matched healthy subjects over the same period were enrolled as the control group. Polymerase chain reaction-ligase detection reaction ( PCR-LDR ) was used to perform genotyping for HDAC9 gene rs11984041 and rs2107595 loci in all subjects. The correlation between genotype and IS was analyzed with multivariate logistic regression analysis. Results ( 1 ) In all the subjects detected, the genotype detected from rs11984041 loci was type CC,and 3 genotypes including CC,CT,and TT were detected from rs2107595 loci. (2) There were significant differences in dominance model (CT+TT,CC) genotypes and allele frequencies among the LAA, SAO, and control group dominance model ( CT +TT, CC ) and (χ2 =8. 635,P=0. 013, χ2 =10. 309,P=0. 006);and there were no significant differences in dominance model (CT+TT,CC) and allele frequencies among the 3 groups (after adjustment all P>0. 017). Compared with the control group,there were significant differences in the CC,CT,and TT genotypes and allele frequencies in the LAA group (χ2 =7. 446;P=0. 006). In the dominance models (CT+TT),there was significant difference in genotype frequencies between the LAA group ( 65. 1%,97/149 ) and the control group (52. 2%,105/201) (χ2 =5. 800;P=0. 016). (3) Multivariate logistic regression analysis showed that in addition to gender,hypertension,smoking,and high level of low-density lipoprotein,the dominance model CT+TT genotype was associated with the LAA type IS ( CT+TT genotype:OR,1. 909,95% CI 1. 055-3. 454,P =0. 033). Conclusion In addition to the risk factors for cerebrovascular disease such as gender,hypertension,smoking,and high level of low-density lipoprotein,HDAC9 gene polymorphisms may be associated with the LAA type IS. rs2107595 locus CT + TT genotype may be an independent risk factor for LAA type IS.
