It is difficult to discuss the issues described above because currently available databases (e.g., https://www.ncbi.nlm.nih.gov/pubmed/?term=SNP+TGF+asthma+control) do not have analyses of polymorphic forms of TGF-β1, TGF-β2, and TGF-β3 genes, which influence the degree of asthma control. Here, TGFB1 is linked to asthma.
