Abstract
BACKGROUND: Complement component 5 (C5) has been described to play an important role in the development and progression of atherosclerosis and cardiovascular disease. Our aim was to determine whether genetic variation of C5 was associated with ischemic stroke (IS) in northeast Chinese population. METHODS: We used a case-control study involving 386 IS patients and 386 non-IS controls from a rural population and determined the genotypes of five polymorphisms (rs12237774, rs17611, rs4837805, rs7026551, and rs1017119) of C5 gene by Snapshot single-nucleotide polymorphism genotyping assays to assess any links with IS. RESULTS: In univariate analysis, rs17611 was significantly associated with IS in the additive model, the dominant model, and recessive model (additive p 0.031, dominant p 0.034, and recessive p 0.027). After adjustment for Binary Logistic Regression, rs17611 polymorphism was still significant in three models (adjusted odds ratio (OR) = 1.306, 95% confidence interval (CI) = 1.069-1.595, p-value = 0.009 in an additive model; OR = 1.378, 95% CI = 1.024-1.856, p-value = 0.035 in a dominant model; and OR = 1.511, 95% CI = 1.048-2.18, p-value = 0.027 in a recessive model). CONCLUSION: In this sample of patients, genetic variation of rs17611 in C5 is associated with higher prevalence of IS.
