Decreased activity or insufficient synthesis of biotransformation enzymes due to genetic polymorphism is a risk factor for various complex diseases, including atopy. Allele-specific hybridization on a biochip was used to evaluate the frequencies of xenobiotic metabolism gene polymorphisms in children with bronchial asthma and/or allergic rhinitis and in healthy donors, all residents of the Republic of Bashkortostan of Russian descent. Polymorphisms of CYP1A1, GSTT1, GSTM1, NAT2, MTHFR, CYP2C9, and CYP2C19 were not associated with atopic diseases in children. The genotype CYP2D6*1934G/G and the allele CYP2D6*1934G were associated with an increased risk of allergic rhinitis in boys. bronchial asthma, allergic rhinitis, polymorphism, association, oligonucleotide biochip, xenobiotic metabolism genes, children |
