Pvhl mutation
WebThe patient was lost to follow-up until age 18 when she developed shortness of breath and was found to have multiple pulmonary metastases identified as pheochromocytoma by biopsy. Genetic testing identified a 3p25-26 (c.482 G>A) VHL gene chromosomal mutation consistent with von Hippel–Lindau disease genotype. WebWhen functional, pVHL acts as an E3 ubiquitin ligase that negatively regulates hypoxia inducible factor (HIF). Genetic mutations that perturb the structure of pVHL result in dysregulation of HIF, causing a wide array of tumor pathologies including retinal angioma, pheochromocytoma, central nervous system hemangioblastoma, and clear cell renal …

The disease is caused by mutations of the Von Hippel–Lindau tumor suppressor (VHL) gene on the short arm of chromosome 3 (3p25-26). There are over 1500 germline mutations and somatic mutations found in VHL disease. Every cell in the body has 2 copies of every gene (bar those found in the sex chromosomes, X and Y). In VHL disease, one copy of the VHL gene has a mu…
