After functional analysis of genes in the coexpression network, five KEGG pathways (“ECM-receptor interaction,” “focal adhesion,” “beta-alanine metabolism,” “PI3K-Akt signaling pathway,” and “pathways in cancer”) contained 8 genes (VWF, LAMB3, LAMA4, CAV1, ALDH1A3, SMOX, GNG4, and PPARG) which were found to be directly related to childhood asthma development and have potential for use as disease progression biomarkers. This evidence concerns the gene ALDH1A3 and asthma.
