SV2B expression levels were higher specifically in TFE3‐RCC tissues than those of TFE3, MLANA, HMB45, and CTSK (Figure 1B).[14] Receiver‐operating characteristic (ROC) curve analysis revealed high area under the curve (AUC) values for SV2B when comparing TFE3‐RCC with ARTs, KIRP, and KIRC (Figure 1C). This evidence concerns the gene TFE3 and renal cell carcinoma.
