IL5RA and asthma: Table 3 shows the top 26 most differentially expressed transcripts between controls and patients with allergic asthma, according to P-value and fold change. The main biological roles of these genes are described in Table 4, which highlights the biological processes related to the immune system. Among these genes, IL5RA attracted our attention as a putative asthma biomarker because it was the best positioned when considering both fold change and P-value data, and because of its role in different immune processes.
