Six single nucleotide polymorphisms (SNPS) of HDAC9 gene were genotyped by SNPscan genotyping technique in 248 patients with LAA-S and 237 controls in Hainan Han population. SNP loci (rs10227612, rs12669496, rs1548577, rs2074633, rs2526626, and rs2717344) were genotyped, and the genotype and allele frequencies were compared between the case and control group. At the same time, the distribution of smoking between the case and control group was compared, and the 3-year and 7-year follow-up smoking cessation between the case and control group was compared, so as to find out the effects of smoking cessation intention and HDAC9 SNP on LAA-S.Results: (1) The GT genotype at rs10227612, GG genotype at rs2717344, and GA genotype at rs1548577 in the case group were significantly higher than those in the control group, and the differences were statistically significant. (2) There were significant differences in the distribution of smoking between the case and control group (P < 0.05), and there were significant differences in the smoking cessation after 3 years and 7 years of follow-up between the case and control group (P < 0.05). The intention to quit smoking was positively correlated with the incidence of LAA-S.Conclusion: (1) The rs10227612, rs1548577, rs2074633, rs2717344 of HDAC9 gene may be significantly related to atherosclerotic cerebral infarction of great arteries in Hainan Han population, while rs12669496 and rs2526626 may not be related. (2) According to the statistics of smoking in the case and control group, smoking was related to large artery atherosclerotic cerebral infarction, and the intention to quit smoking was a very important factor affecting the success of smoking cessation.Keywords: HDAC9, SNP, LAA-S, Hainan nationality, willingness to quit smoking |
