Among the most significant, we found antigen processing and presentation, Staphylococcus aureus infection, autoimmune thyroid disease, graft-versus-host disease, oxidative phosphorylation, natural killer cell-mediated cytotoxicity, and intestinal immune network for IgA production, with enrichment signals of approximately 37%, 35%, 43%, 44%, 40%, 34%, and 37%, respectively. The gene discussed is CD79A; the disease is graft versus host disease.
