The aim of the study was to investigate the role of ADRB2 gene polymorphism in the pathogenesis of atopic diseases in children from Belarus. A total of 276 children with atopic BA, 111 patients with atopic dermatitis and control sample from Belarus were analyzed. PCR-RFLP method was used for studying polymorphisms Arg16Gly (rs1042713) and Gln27Glu (rs1042714) of the ADRB2 coding β2-adrenoreceptor. The association of the 16Gly allele of polymorphic variant Arg16Gly with an increased risk of atopic diseases was found (OR = 1.28, 95% CI 1.01–1.63). The genotype 16ArgArg is protective for the development of pathology (OR = 0.48, 95% CI 0.29–0.79). The association of the genotype 27GluGlu of polymorphism Gln27Glu with predisposition to atopic dermatitis (OR = 1.89, 95% CI 1.09–3.30) and a decrease in the probability of bronchial asthma addition (OR = 0.47, 95% CI 0.28–0.80) was revealed. The results obtained can be used to predict the atopic diseases onset and course.
