TCGA data analysis demonstrated that patients with high UBQLN4 mRNA levels had significantly lower OS than patients with low UBQLN4 mRNA levels in Adrenocortical Carcinoma (ACC), BRCA, COAD, CESC, Kidney Renal Clear Cell Carcinoma (KIRC), KIRP, LIHC, LUAD, Mesothelioma (MESO), Pancreatic Adenocarcinoma (PAAD), Pheochromocytoma and Paraganglioma (PCPG), Sarcoma (SARC), SKCM, and UCEC.
