Association of endothelial nitric oxide synthase gene G894T polymorphism with blood oxygen transport.

Background: Nitric oxide (NO) is involved in formation of oxygen transport function of blood and oxygen transport in tissues by means of interaction with haemoglobin. Endothelial nitric oxide synthase gene G894T polymorphism affects the expression and the activity of the NO synthase enzyme. The influence of this polymorphism on the formation of oxygen-dependent processes in the body has not been completely investigated.
