Moreover, nearly half of the genes whose expression in airway epithelium is associated with TAGC SNPs are also DE in atopic asthma. Our findings support a key role of regulation of airway epithelial gene expression on atopic asthma in children.FootnotesThis manuscript has recently been accepted for publication in the European Respiratory Journal.
