ANALYSIS OF ASSOCIATION OF VDR GENE VARIANTS WITH SERUM VITAMIN D LEVEL IN PATIENTS WITH BONE-MUSCULAR DISEASE

Currently, the pathology of the musculoskeletal system is considered in several multifactorial diseases, the pathogenesis of which is complex and is due to the interaction of environmental and endogenous factors. An important role in the progression of pathology is played by disorders in metabolism and a decrease in sensitivity to vitamin D. Studies of the past two decades have shown that the various biological actions of the active metabolite of vitamin D - 1,25-dihydroxy vitamin D (calcitriol) - are carried out by modulating the expression of genes that are mediated by interaction with the intracellular vitamin D receptor (VDR). VDR is a product of the corresponding gene - VDR, which determines its structure and functional activity. In this gene, a certain number of polymorphic variants have been identified that can affect gene expression.
