Objective. To analyze the distribution of variant alleles of single nucleotide of the BSMI VDR gene polymorphism in children with vitamin D-deficient rickets.

 

Patients and methods. A total of 118 children in the age from 3 to 12 months who had clinical signs of vitamin D-deficient rickets were under observation. A clinical and anamnestic examination of children, determination of serum concentration of 25 (OH) D and genetic study of the BSMI VDR gene polymorphism is conducted.

 

Results. Determination of the distribution of genotypes of polymorphic marker BsmI as follows: the first group – genotype bb carriers (39 (33%) of children), the second group — genotype Bb carriers (57 (48.3%)), the third group — genotype BB carriers (22 children (18.7%)).Vitamin D deficiency is significantly more frequently diagnosed in people with genotype bb (p<0.05).

 

Conclusions. The association of BsmI VDR gene polymorphism with vitamin D-deficient rickets in children was analyzed at first. The relation of vitamin D deficiency with the genotype of the BsmI polymorphic marker is found.

 

Key words: rickets, infants, VDR gene polymorphism, hydroxyvitamin D.
