CD79A and inborn error of immunity: The KEGG pathway enrichment results also demonstrated that immune-related DEGs were closely associated with immune processes—for example, Th1 and Th2 cell differentiation, antigen processing and presentation, Th17 cell differentiation, natural killer cell-mediated cytotoxicity, cytokine–cytokine receptor interaction, primary immunodeficiency, T cell receptor signaling pathway, viral protein interaction with cytokine and cytokine receptor, and intestinal immune network for IgA production.
