The results showed that a high level of BAIAP2L2 indicated poor DFS in BRCA (p = 0.027), LIHC (p = 0.0061), and testicular germ cell tumors (TGCTs) (p = 0.048) and good DFS in pheochromocytoma and paraganglioma (PCPG) (p = 0.044) and UCEC (p = 0.014) (Figure 2A). The gene discussed is BAIAP2L2; the disease is testicular germ cell tumor.
