The study of children under one year of age for molecular genetic testing-VDR (rs1544410, rs2228570), RANKL (rs9594738, rs9594759) with the study of the frequency distribution of alleles and genotypes by polymorphisms, analysis of the relationship of molecular genetic markers with indicators of bone metabolism.


Children under the age of one year of Kazakh nationality born in Aktobe will be examined.

Each child included in the study will have an individual registration card, where information about the health status of the child and the health status of the mother during pregnancy will be filled in.

A biochemical analysis will be determined for the level of calcium, phosphorus, calcitonin, parathyroid hormone, osteocalcin, vitamin D in blood serum and deoxypyridinoline in urine.

Blood will be taken to determine the genetic polymorphism of VDR (rs1544410, rs2228570), RANKL (rs9594738, rs9594759).

The state of bone tissue remodeling (osteocalcin, vitamin D, Ca, P, calcitonin, deoxypyridinoline) will be revealed The frequencies of allelic variants of the VDR (rs1544410, rs2228570), RANKL (rs9594738, rs9594759) genes in children under the age of one year in the population of Kazakhstan were determined.
