FER1L4 and central nervous system cancer: Noticeably, otoferlin expression was strongly significantly correlated with survival in renal clear cell carcinoma (KIRC–p < 10−5); myoferlin expression was strongly significantly correlated with survival in brain lower grade glioma (LGG–p < 10−4) and pancreatic adenocarcinoma (PAAD–p < 10−4), and Fer1l4 expression was strongly significantly correlated with survival in bladder urothelial carcinoma (BLCA–p < 10−5) and kidney renal clear cell carcinoma (KIRC–p < 10−5).
