Von Hippel-Lindau syndrome (VHL) is a hereditary condition associated with tumors arising in multiple organs. VHL-related tumors include hemangioblastomas, which are blood vessel tumors of the brain, spinal cord, and retina.
Is VHL a genetic disorder?
VHL Syndrome: What You Need to Know Because VHL syndrome is genetic, there is a chance that your relatives may have the mutation as well. Eighty percent of cases are inherited from a parent who has VHL syndrome.
Is VHL considered cancer?
A rare, inherited disorder that causes tumors and cysts to grow in certain parts of the body, including the brain, spinal cord, eyes, inner ear, adrenal glands, pancreas, kidney, and reproductive tract. The tumors are usually benign (not cancer), but some may be malignant (cancer).
Is there a cure for von Hippel-Lindau disease?
How Is Von Hippel-Lindau Syndrome (VHL) Treated? Although there is no cure for VHL, the associated tumors can be treated. Early detection and treatment of tumors significantly improves a patient’s diagnosis. Left untreated, VHL may result in blindness, permanent brain damage, or death.
What are the symptoms of von Hippel-Lindau disease?
Symptoms of von Hippel-Lindau (VHL) disease vary among patients and depend on the size and location of tumors . Hemangioblastomas that develop in the brain and spinal cord can cause headaches, vomiting, weakness, and a loss of muscle coordination ( ataxia ).
What is VHL gene mutation?
Mutations in the VHL gene cause von Hippel-Lindau syndrome. The VHL gene is a tumor suppressor gene, which means it keeps cells from growing and dividing too rapidly or in an uncontrolled way. Mutations in this gene prevent production of the VHL protein or lead to the production of an abnormal version of the protein.
What chromosome is VHL gene on?
VHL disease is an autosomal dominant disorder resulting from a deletion or mutation in the VHL gene located on the short arm of chromosome 3. Each child of a person with VHL is at 50% risk of inheriting the altered copy of the gene.
Who treats VHL?
Additional specialists may include a nephrologist, endocrinologist or neurologist, among others. VHL is a disorder characterized by multiple tumors, which can be cancerous or noncancerous. Hemangioblastomas of the central nervous system (brain and spinal cord) are some of most common tumors found in VHL.
Is VHL fatal?
Although they are typically noncancerous, they can cause serious or life-threatening complications. Hemangioblastomas that develop in the brain and spinal cord can cause headaches, vomiting, weakness, and a loss of muscle coordination (ataxia).
What causes VHL disease?
Von Hippel-Lindau (VHL) disease is caused by a mutation in the VHL gene . This gene is a tumor suppressor gene , which helps to control cell growth. Mutations in the VHL gene lead to a lack of regulation of cell growth and survival, allowing cells to grow and divide uncontrollably.
What is the function of the von Hippel-Lindau protein?
von Hippel–Lindau (VHL) Protein The VHL protein functions as a subunit of a multiprotein ubiquitin ligase that negatively regulates expression of a large collection of hypoxia-inducible genes controlled by hypoxia-inducible transcription factors (HIFs).
Is the von Hippel-Lindau gene an oncogene or a tumor suppressor?
The Von Hippel–Lindau tumor suppressor also known as pVHL is a protein that, in humans, is encoded by the VHL gene. Mutations of the VHL gene are associated with Von Hippel–Lindau disease….Von Hippel–Lindau tumor suppressor.

What is von Hippel-Lindau disease?
Death is usually caused by complications of brain tumors or kidney cancer. Von Hippel-Lindau disease (VHL) is a rare, genetic multi-system disorder in which non-cancerous tumors grow in certain parts of the body.
What are the types of tumors associated with von Hippel-Schönlein disease (VHL)?
The types of tumors associated with VHL disease include hemangioblastomas (slow-growing tumors of the central nervous system); kidney cysts and clear cell renal cell carcinoma; pancreatic neuroendocrine tumors; pheochromocytomas (noncancerous tumors of the adrenal glands); and endolymphatic sac tumors.
What are the symptoms of von Hippel-Hagen syndrome (VHL)?
Symptoms of VHL vary among individuals and depend on the size and location of the tumors. Symptoms may include headaches, problems with balance and walking, dizziness, weakness of the limbs, vision problems, deafness in one ear, and high blood pressure. Individuals with VHL are also at a higher risk than normal…
How is renal cell carcinoma (RCC) treated in von Hippel-Lindau (VHL) disease?
It is generally agreed that a nephron-sparing approach is the optimum strategy for managing RCC in VHL disease. As most patients and gene carriers should be under regular surveillance (see below) many RCC are detected presymptomatically during routine annual renal imaging and usually do not require immediate intervention.
