CD79A and inborn error of immunity: In terms of immune-related pathways, the present study found that immune-related DEGs were enriched in multiple immune-related pathways, including Th1 and Th2 cell differentiation, antigen processing and presentation, cytokine–cytokine receptor interaction, Th17 cell differentiation, viral protein interaction with cytokine and cytokine receptor, natural killer cell mediated cytotoxicity, T cell receptor signaling pathway, primary immunodeficiency, and intestinal immune network for IgA production.
