We found that a high correlation between miRNA and immune-related pathways, including the Chemokine signaling pathway, primary immunodeficiency, graft-versus-host disease, hematopoietic cell lineage, and intestinal immune network for IgA production, was associated with better survival among samples from Luminal A but with worse survival among samples from Luminal B subtype (Fig. 4B). The gene discussed is CD79A; the disease is graft versus host disease.
