We discovered that the majority of the immune-related genes had a relationship with the expression of C5orf34 and that a positive relationship was observed between the immune-related genes and C5orf34 expression (including immunoinhibitors, chemokine receptors, MHC, chemokine ligands, and immunostimulators) in most of the several cancers (Figure 10). The gene discussed is HLA-C; the disease is cancer.
