Analysis via GEPIA2 revealed that, in breast cancer (BRCA), esophageal cancer (ESCA), glioblastoma multiforme (GBM), head and neck cancer (HNSC), low-grade glioma (LGG), hepatocellular carcinoma (LIHC), lung adenocarcinoma (LUAD), cutaneous melanoma (SKCM), and uveal melanoma (UVM), higher BAP31 expression was associated with reduced OS (Figure 3A–I, p < 0.05). The gene discussed is BCAP31; the disease is low grade glioma.
