Among thirty-six tumor types excluding uveal melanoma, PTPN12 was associated with CD8+ T cell infiltration in eight tumors including bladder urothelial carcinoma (BLCA), cholangio carcinoma (CHOL), and lymphoid neoplasm diffuse large B-cell lymphoma (DLBC); KDELR2 was associated with CD8+ T cell infiltration in four tumors including DLBC, rectum adenocarcinoma (READ), and sarcoma (SARC); P2RX4 was associated with CD8+ T cell infiltration in adrenocortical carcinoma (ACC) and skin cutaneous melanoma (SKCM); IDH2 was only associated with CD8+ T cell infiltration in thymoma (THYM). This evidence concerns the gene KDELR2 and rectum adenocarcinoma.
