CD79A and graft versus host disease: According to the result of GSEA, we found that multiple immune-related pathways were significantly enriched in the higher expression group of hub genes like allograft rejection, primary immunodeficiency, intestinal immune network for IgA production, T cell receptor signaling pathway, B cell receptor signaling pathway, autoimmune thyroid disease, graft-versus-host disease, human T cell leukemia virus 1 infection, leukocyte transendothelial migration, Th1 and Th2 cell differentiation, Th17 cell differentiation, and asthma.
