Prevalence of endothelial nitric oxide synthase gene polymorphisms in patients with atopic asthma

Abstract

Neither the NOS3 'b' allele nor the NOS3 'b/b' genotype showed any general association with atopic asthma, but they were associated with atopy-related phenotypes. We conclude that the NOS3 gene polymorphisms may act as disease modifiers in atopic asthma phenotype in our population.
