HLA-A and neoplasm: An HLA genotyping confirmed the patient cells as the origin of the XABCL tumor (HLA-A*02:01, A*30:02, B*18:01, B*49:01, Cw*05:01, Cw*12:03, DRB1*03:01, DRB1*11:01, DQB1*02:01, DQB1*03:01), and we confirmed that both the XABCL-LCL and the PBMCs from the patient—but not the TNBC-T cells—were EBV+ by qPCR (data not shown).
