EGFR and inborn error of immunity: Subsequently, KEGG enrichment analysis of each module genes showed that the interaction pathways in each module (Figure 10A) were mainly enriched in neuroactive ligand‐receptor interaction, cytokine‐cytokine receptor interaction, primary immunodeficiency, viral protein interaction with cytokine and cytokine receptor, natural killer cell‐mediated cytotoxicity, graft‐versus‐host disease, regulation of actin cytoskeleton, and MAPK, Rap1, Ras, IL‐17, ErbB, B‐cell receptor, and other signaling pathways.
