In von Hippel-Lindau syndrome, which organ is at risk for clear cell carcinoma?

Explanation:
Loss of function of the VHL tumor suppressor gene leads to accumulation of hypoxia-inducible factors, which drives angiogenesis and tumor formation. This mechanism specifically promotes clear cell renal cell carcinoma, making the kidneys the organ at risk for this cancer in von Hippel-Lindau syndrome. While other features of the syndrome include brain and retinal hemangioblastomas, pheochromocytomas, and pancreatic cysts or neuroendocrine tumors, the clear cell carcinoma most characteristically involves the kidney.
