The aim of the study was to evaluate a role of transforming growth factor"β1 (TGF"β1) gene rs1800470 single nucleotide polymorphisms (SNPs), cytotoxic T"lymphocyte"associated protein 4 (CTLA4) gene rs231775 SNPs and hedgehog"interacting protein (HHIP) gene rs1828591 SNP for predisposition to bronchial asthma (BA) in Krasnoyarsk residents. Methods. The study involved 100 asthma patients and 338 control subjects. The control group included a representative population sample of Siberian urban residents without respiratory diseases who had participated in the WHO MONICA (Multinational Monitoring of Trends and Determinants in Cardiovascular Disease) and the HAPIEE (Health, Alcohol and Psychosocial factors In Eastern Europe) projects. Results. There was a significant difference in genotype and allele frequency distribution of the TGFβ gene in patients with non"allergic BA vs controls. Therefore, A allele carriers with heterozygous genotype AG and homozygous genotype AA of rs1800470 polymorphism of the TGF"β1 gene were at high risk of non"allergic BA. We also found an increase in the GG genotype frequency in BA group compared to the control group. The GG genotype of CTLA4 gene rs231775 polymorphism was associated with high risk of allergic BA (ОR = 2.036; 95% CI = 1.16–3.58; р = 0.012). Genotype and allele frequency distribution of HHIP gene rs1828591 polymorphism did not differ significantly between BA patients and the control group. Conclusion. An association was revealed between BA, TGF"β1 gene rs1800470 SNPs and CTLA4 gene rs231775 SNPs. An association between BA and HHIP gene rs1828591 SNPs was not found.
