Abstract
BackgroundThe goal of the present study was to determine whether endothelin-1 (EDN1) variants are associated with intracerebral hemorrhage (ICH) risk among Chinese Han people.Material/MethodsThe genotyping of EDN1 rs5370 and rs6458155 polymorphisms were conducted in 154 ICH patients and 168 healthy controls using polymerase chain reaction (PCR) and sequencing. Deviation for genotype frequencies in controls from Hardy-Weinberg equilibrium (HWE) was assessed. The genotype and allele distribution of EDN1 polymorphisms was checked via χ2 test between 2 groups. Strength of the association between EDN1 polymorphisms and ICH risk is presented by odds ratio (OR) and 95% confidence interval (95% CI).ResultsGenotype distribution for rs5370 and rs6458155 polymorphisms in the control group both conformed to HWE (P>0.05). Only CC genotype and C allele frequencies of rs6458155 between ICH patients and healthy individuals were significantly different (P=0.025; P=0.043), indicating rs64581255 is associated with increased ICH onset (OR=2.214, 95% CI=1.009–4.461; OR=1.389, 95% CI=1.010–1.910). When adjusted by confounding factors, the significant correlations still existed between 2 groups (P=0.028, adjusted OR=2.217, 95% CI=1.092–4.500; P=0.046, adjusted OR=1.386, 95% CI=1.005–1.910).ConclusionsEDN1 rs6458155 polymorphism may be a risk factor of ICH among Chinese Han people.
