When comparing all tumor types with HBMR available, median CD8 T cell abundance score was negatively correlated with immune dN/dS in the HLA-A0201 immunopeptidome (r = −0.7, P = 0.0035; Fig. 2d), but not to HBMR in the proto-HLA (r = −0.38, P = 0.16; Fig. 2e). The gene discussed is CD8A; the disease is neoplasm.
