As shown in Figure 7C, the expression of ABCG2 in 19 different cancers is significantly correlated with TMB, of which ABCG2 gene expression is positively correlated with a high mutation status in LIHC, LAML, and HNSC, and with a low mutation status in lymphoid neoplasm diffuse large B-cell lymphoma (DLBC), KICH, LUAD, pancreatic adenocarcinoma (PAAD), pheochromocytoma and paraganglioma (PCPG), PRAD, READ, ACC, uveal melanoma (UVM), UCEC, THCA, STAD, SKCM, SARC, BRCA, and CESC. The gene discussed is ABCG2; the disease is diffuse large B-cell lymphoma.
