Preventive and Personalized Medicine (2021-2023)

To research for a genetic marker of bronchial asthma, a single nucleotide polymorphism (SNP) analysis of DNA obtained from the peripheral blood of patients with bronchial asthma and normal control will be performed.

Detailed Description

Unrelated Kazaks subjects who have bronchial asthma were recruited in the current study. Genotyping for various SNP associated due to the linkage disequilibrium patterns is to be performed. Genotypes would be statistically compared between patients with bronchial asthma and normal control subjects free of bronchial asthma
