It should be emphasized that only a part of the listed genes have been verified here as probable markers of asthma-driven fibrosis (Fn1, C3, C3ar1, Cyp2e1, Col4a1, and Col4a2); an investigation of the marker function of residuary genes (Thbs1, Ccr3, Ccl6, Ccl9, Tnc, and Itgb6) in pulmonary fibrosis is the subject of future studies. This evidence concerns the gene COL4A2 and asthma.
