The results of GSEA enrichment analysis are shown in Figure 5, which are primarily enriched in antigen processing and presentation, cell adhesion molecules (CAMs), chemical signaling pathway, T cell receiver signaling pathway, B cell receiver signaling pathway, the internal immune network for IgA production, primary immunodeficiency, natural killer cell modified cytotoxicity, and other signaling pathways, and some additional immune-related signaling pathways. Here, CD79A is linked to inborn error of immunity.
