Abstract

The goal of the study was to elucidate the impact of the single nucleotide variants rs11466749 of the thymic stromal lymphopoietin gene, rs_7216389 of the orsomucoid-1-like protein 3 gene, and rs10052957 of the human nuclear glucocorticoid receptor subfamily 3, group C, member 1 gene on the development of the mono-organic phenotype “atopic eczema” or the poly-organic “atopic eczema + allergic rhinitis/allergic rhino-conjunctivitis”. We recruited 101 patients into the main and 105 into control groups aged from 3 to 18 years old. Patients of the main group suffered from atopic eczema (58 children) and atopic eczema + allergic rhinitis/allergic rhino-conjunctivitis (43 children). Patients of the control group suffered from the digestive tract pathology. Main group patients were genotyped for the A/A, A/G, G/G of rs11466749, C/T, C/C and T/T of rs_7216389 and A/A, A/G and G/G of rs10052957; patients of the control group were genotyped for the A/A, A/G, G/G of rs11466749, C/T, C/C and T/T of rs_7216389 by polymerase chain reaction in real time with restricted fragment length polymorphism. Results: no significant differences in rs11466749 among the main and control groups, the most common variant is A/A – 55.2% (mono-organic) and 55.8% (poly-organic); T/T rs_7216389 is significantly the most common in poly-organic phenotype – 39.5%; rs10052957: A/G variant is significantly most common in mono-organic phenotype – 51.7% and G/G – in the poly-organic phenotype – 62.8%. The G/G rs11466749 variant has a trending to significance direct 0.173 association and increased odds ratio = 5.85 (0.63-54.31) for the polyorganic phenotype and protective impact onto the mono-organic phenotype -0.173 (0.17 (0.02-1.59); T/T rs7216389 variant increases the risk of poly-organic phenotype: 0.227, odds ratio = 2,79 (1.14-6.85) and decreases the risk of monoorganic” phenotype: -0.227, 0.36 (0.15-0.88); A/G rs_10052957 variant significantly increases the risk the mono-organic phenotype: 0.215, odds ratio = 2.5 (1.08-5.56)) and decreases risk of poly-organic phenotype: 0.215, odds ratio = 0.4 (0.18-0.93); G/G rs_10052957 variant significantly increases the risk of the poly-organic phenotype: 0.263, odds ratio = 2.97 (1.31-6.74)) and decreases for the mono-organic phenotype: -0.263, odds ratio = 0.34 (0.15-0.76)). Genotype variant T/T rs_7216389 of the orsomucoid-1-like protein 3 gene significantly increases the risk of developing the poly-organic atopic phenotype by 2.79 times and protects against the mono-organic atopic phenotype by 0.34 times. G/G genotype variant of rs10052957 of the human glucocorticoid receptor subfamily, group C, member 1 gene significantly increases the risk of developing the poly-organic phenotype by 2.97 times, protecting against mono-organic atopic phenotype by 0.34 times
