TEX19 and renal carcinoma: Analysis of two independent kidney cancer data sets (KIRK and KIRP) reveals that both show significant reductions of overall survival for the higher TEX19 expression cohort of patients (Additional file 10: Figure S6a/b); KICH is a rare renal cancer, only contributing to approximately 5% of all renal cancers [58], and it has a better prognosis than more common forms of renal cancer [59], so limited data excluded it from individual analysis.
