The results showed that the AUC of these six prognostic MTGs was ACAD11 (AUC = 0.669, P < 0.001), ACADSB (AUC = 0.943, P < 0.001), BID (AUC = 0.897, P < 0.001), PYCR1 (AUC = 0.710, P < 0.001), SLC25A27 (AUC = 0.591, P = 0.012), and STAR (AUC = 0.607, P = 0.003), which showed good diagnostic accuracy for ccRCC (Figure S2). The gene discussed is BID; the disease is nonpapillary renal cell carcinoma.
