The analysis of frequency of genotypes and alleles for the ER22/23EK polymorphism in the GR gene with regard to the age of BA onset demonstrated a significant difference between patients with early-onset and late-onset asthma (p = 0.035). A significant difference was revealed in the distribution of alleles and genotypes for the Tth111I polymorphism in the GR gene between patients with early-onset BA and late-onset BA (p = 0.006). No correlation was found between the ER22/23EK polymorphism in the GR gene and late-onset BA in all genetic models; also, there was a reduction in the risk of early-onset BA observed in the dominant and additive models. No association was demonstrated between the Tth111I polymorphism in the GR gene and late-onset asthma, while a statistically significant correlation was shown with the risk of early-onset asthma in the dominant and super-dominant models. popup.nrat_date 2025-05-12 Close
