Expression levels of IL18RL1 (P = 0.019, MA and 0.0008, SA), IL1RL1 (P = 0.0034, MA and 0.010, SA), and ORMDL3 (P = 0.040, MA and 0.0029, SA) were higher in both mild-moderate and severe asthma subjects compared to controls (Figures 5A,B,D) whereas expression levels of MUC5AC (P = 0.022) and RPS26 (P = 0.0004) were higher in severe asthma subjects only compared to controls (Figures 5C,E). Here, IL1RL1 is linked to asthma.
