Prevalence of endothelial nitric oxide synthase gene polymorphisms in patients with atopic asthma
Original language description
Asthma is a common multifactorial disease, the etiology of which is attributable to both environmental and genetic factors. The endothelial nitric oxide synthase (NOS3) gene has been implicated in asthma pathogenesis.This study investigated associationsof 27 base-pair tandem repeat polymorphism in intron 4 and the Glu298Asp (G894T) variant of the NOS3 gene with atopic asthma in a Czech population. Polymerase chain reaction was used to determine the NOS3 genotypes in subjects with atopic asthma (n=163)and random controls (n=209). The NOS3 allele or genotype distributions did not significantly differ between the control and asthma groups. However, the common genotype (bb) of the NOS3 polymorphism in intron 4 was found to be significantly associated with total IgE levels (P=0.006), specific IgE levels for feathers (p=0.0002) and a positive skin prick test for hay (P=0.004). In one atopic patient, we identified an additional 27-bp repeat in the NOS3 gene (NOS3c), which occurred in hetero
