A study of the role of polymorphic variants of genes involved in the glucocorticosteroid metabolism in the development and course of bronchial asthma in individuals from the Republic of Bashkortostan

Abstract

Inhaled glucocorticosteroids (GCS) are one of the most commonly used groups of anti-inflammatory drugs prescribed to asthma treatment. The aim of this work has been to perform a meta-analysis of the associations of polymorphic variants of genes involved in GCS metabolism or associated with sensitivity to GCS treatment according to GWAS with asthma development, age of manifestation and severity in individuals of Russian, Tatar, and Bashkir ethnicity. DNA samples of 846 of asthma patients and controls aged 3 to 67 years from the Republic of Bashkortostan have been used in the study. A meta-analysis of the associations of 10 polymorphic variants of studied genes with asthma development and clinical course severity in individuals of Russian, Tatar, and Bashkir ethnicity has been carried out. The associations of the rs10044254*T allele of the FBXL7 gene and the rs1876828*T allele of the CRHR1 gene with risk of asthma development, the rs10044254*T allele of the FBXL7 gene and the rs2395672*G allele of the CMTR1 gene with asthma manifestation in childhood, the rs1876828*T allele of the CRHR1 gene with severe and moderate asthma have been found.
