Study of apolipoprotein E genetic polymorphism in patients with atherosclerotic cerebral infarction

摘要

Objective: To explore the frequency and significance of ApoE gene polymorphisms in Chinese patients with atherosclerotic cerebral infarction (ACI) - Methods: Polymerase chain reaction and gene sequencing, single nucleotide polymorphisms of ApoE gene were used to analyze 33 cases of patients with ACI and 35 controls. Results: The frequencies of ApoE gene single nucleotide polymorphisms 465C/G, 462C/G and 451 delC in the ACI group were significantly higher than those in the control group (P < 0.05). The prevalence of polymorphism 486G/T in the control group was significantly higher than that in the ACI group (P = 0.011). Conclusions: 465C/G, 462C/G and 451 delC polymorphisms might be associated with ACI . 486GT allele might have protective effect on the pathogenesis of ACI.
