For a more detailed pathway enrichment analysis, GSVA revealed that taste transduction, α‐linolenic acid metabolism, chondroitin sulphate glycosaminoglycan biosynthesis, basal cell carcinoma, cell membrane DNA sensing pathway, haematopoietic cell lineage, primary immunodeficiency, psoriasis, intestinal immune network promoting IgA production, type I diabetes, p53 signalling pathway, sulphur metabolism, systemic lupus erythematosus, complement and coagulation cascade were highly expressed in the low‐risk group. The gene discussed is CD79A; the disease is inborn error of immunity.
