Children with severe asthma had higher median serum levels of TNF‐α (10.56 [6.17–13.14] vs. 8.83 [5.07–20.11] pg/mL, p = 0.043) and IL‐5 (7.29 [1.38–28.54] vs. 4.06 [1.13–31.63] pg/mL, p = 0.010) compared with those with non‐severe asthma, whereas IFN‐γ, IL‐10, IL‐17, and IL‐4 did not differ between groups (Figure 2). The gene discussed is IL17A; the disease is asthma.
