A 2023 study focused on a rare pediatric renal tumor, clear cell sarcoma of the kidney (CCSK), showed that tumors with the BCOR internal tandem duplication (ITD), which is the most common driver mutation in CCSK, exhibit increased JUND expression (as well as increased Fibroblast growth factor 3 [FGF3], Vascular endothelial growth factor A [VEGFA], Secreted phosphoprotein 1 [SPP1], and Adrenomedullin [ADM]) [181] (Table 6). The gene discussed is ADM; the disease is clear cell sarcoma of kidney.
