It was identified that HAVCR2 had positive infiltration scores in all cancer types, whereas a negative infiltration score was noted for CXCL13 (in LGG and DLBCL), LAG3 (in DLBCL and AML), LAYN (in CHOL, KICH, AML, LGG, PCPG, THCA and UCS), PDCD1 (in DLBCL, AML and THYM) and TIGIT (DLBCL and AML). This evidence concerns the gene PDCD1 and diffuse large B-cell lymphoma.
