[Retinal vascular occlusion and polymorphisms in genes coding for components of vitamin K cycle]. / Okkliuziia sosudov setchatki i polimorfizm genov, kodiruiushchikh komponenty tsikla vitamina K.

In recent years, more and more attention has been paid to the role of polymorphisms in genes that code for the components of vitamin K cycle in the development of retinal vascular occlusion. Vitamin K serves as a cofactor for a number of blood coagulation factors, namely, factor II, VII, IX, and X, and also for anticoagulation proteins C and S. According to the literature, 1639G4A polymorphism of the vitamin K epoxide reductase complex subunit 1 gene (VKORC1) is likely to be a new risk factor of retinal vascular occlusion.
