To identify immune‐modulating genes that correlate with the prognosis of patients with DLBCL, we conducted a prognosis analysis that stratified the expression of 43 genes reported as immune checkpoint molecules or their ligands including, ADORA2A, B2M, BTLA, CD24, CD27, CD28, CD40, CD40LG, CD47, CD70, CD80, CD86, CD247, CD274, CD276, CIITA, CTLA4, CYBB, HAVCR2, ICOS, ICOSLG, IDO1, IL2RB, KIR3DL3, LAG3, LGALS9, NCR3, PDCD1, PDCD1LG2, PVR, PVRL2, SIGLEC10, SIGLEC7, SIRPA, TIGIT, TNFRSF18, TNFRSF4, TNFRSF9, TNFSF14, TNFSF18, TNFSF4, TNFSF9, and VTCN1. The gene discussed is CD247; the disease is diffuse large B-cell lymphoma.
