Relationship between the ACE gene I/D and AT1R gene A1166C polymorphisms and cerebral infarction / 临床神经病学杂志

ABSTRACT

Objective To explore the relationship between angiotensin I-converting enzyme(ACE)gene I/D and angiotensin Ⅱ type 1 receptor(AT1R)gene A1166C polymorphisms and cereral infarction(CI).Methods ACE and AT1R genotypes were investigated with the method of PCR-RLFP in 88 patients with CI and compared with 90 age-matched population controls.Results AC genotypic frequency(31.8%)and C allele frequency(15.9%)of AT1R gene in CI group were significently higher than those in control group(11.1%,5.6%)(all P0.05).Conclusions The polymorphism of AT1R A1166C is related to the incidence of CI.There are synergistic effects of ACE DD genotype and AT1R gene A1166C polymorphisms on the risk of CI.
