Objective: To explore the association between apolipoprotein AI (ApoAI) gene rs12721026 polymorphism and cerebral hemorrhage (CH) in Changsha Han population, and to evaluate the effect of rs12721026 polymorphism on plasma lipid levels.
Methods: A total of 273 patients with CH and 140 healthy controls were collected. The rs12721026 polymorphism of ApoAI was analyzed by SNaPshot genotyping analysis and DNA sequencing. The total cholesterol (TG), triglyceride (TC), HDL-C and LDL-C were examined by oxidase method.
Results: There was no significant difference in the genotype and allele frequencies of rs12721026 polymorphism between the CH group and the control group (P>0.05). Both in the CH group and in the control group, the level of HDL-C of the TT gene type of rs12721026 was significantly higher than that of the GT/GG gene type (P<0.05). There was no significant difference in the levels of TG, TC and LDL-C among different subgroups of gene types.
Conclusion: There may be no association between apoAI gene rs12721026 polymorphism with CH in Changsha Han population, which may still influence the HDL-C levels.
