Mutations in the tumor suppressor gene von Hippel-Lindau (VHL) underlie a hereditary cancer syndrome—VHL disease—and are also frequently observed in sporadic renal cell carcinoma of the clear cell type (ccRCC). VHL disease is characterized by malignant and benign tumors in a few specific tissues, including ccRCC, hemangioblastoma and pheochromocytoma. The etiology of these tumors remains unresolved. |
