Low expression of UBQLN4 mRNA was correlated with longer OS in LAML and melanoma; longer distant metastasis-free survival (DMFS), progression-free survival (PFS), and DSS in BRCA; longer DSS in multiple myeloma; and shorter OS in glioma according to GEO database (Figures 2(l)–2(s)) [27–33]. The gene discussed is UBQLN4; the disease is AL amyloidosis.
