Analysis of the endothelial nitric oxide synthase gene as a modifier of the cerebral response to ischemia.
We studied the endothelial nitric oxide synthase (eNOS or NOS-3) gene as a potential modifier of the cerebral response to ischemia by investigating the association of two common polymorphisms with ischemic stroke volume. We genotyped an intronic variable number tandem repeat and a single nucleotide polymorphism, G894T, in 132 patients with nonlacunar ischemic strokes in whom clinical data and stroke lesion volume were recorded. Our results show that all genotypes are in Hardy-Weinberg equilibrium. After adjustment of covariates, neither of the NOS-3 polymorphisms showed significant differences comparing the genotypes and mean stroke volume (analysis of variance). Our results do not suggest a major gene effect of the NOS-3 gene as a modifier of the cerebral response to ischemia.
