CD79A and inborn error of immunity: Figure 2F clearly showed that some pathways correlated with the immune system were enriched in Cluster 1, such as the T‐cell receptor signaling pathway, primary immunodeficiency, cytotoxicity mediated by natural killer cells, the intestinal immune network for producing IgA, the interaction of cytokine–cytokine receptors, the B‐cell receptor signaling pathway and the chemokine signaling pathway.
