PMEL and renal cell carcinoma: 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).
