To date, more than 20 genome-wide association studies (GWAS) of the response to asthma treatment showed a large number of loci associated with individual sensitivity to asthma treatment, including variants at GLCCI1, TBXT, FBLX7, ALLC, SPATS2L, THRB, SLC22A15, ALDH7A1, PSAP, and SCG3 (http://www.ebi.ac.uk/gwas/, accessed on 10 September 2024). Here, THRB is linked to asthma.
