How is Von Hippel-Lindau diagnosed?
The only way to confirm VHL is by genetic testing to see if you have the gene mutation. If anyone in your family has Von Hippel-Lindau disease, ask your healthcare provider if genetic testing is right for you. Healthcare providers often diagnose VHL after someone has symptoms related to a VHL tumor.
What is VHL RCC?
von Hippel-Lindau (VHL) disease is an autosomal dominant hereditary disorder characterized by retinal and CNS hemangioblastomas, pheochromocytoma, and clear cell renal cell carcinoma.
What is VHL gene?
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 cancers does VHL cause?
Patients with VHL syndrome have an increased risk of certain types of cancer, especially kidney cancer and pancreatic cancer. The signs and symptoms of VHL syndrome usually do not appear until young adulthood. It is caused by a mutation (change) in the VHL gene.
How many RCC patients have VHL?
The incidence of VHL disease is about 1 per 36,000 live births. The most common VHL-related tumors are found in the central nervous system (CNS) and include hemangioblastomas and endolymphatic sac tumors.
Where is the VHL gene located?

Is VHL a disability?
Malignant VHL that is resistant to treatment, is inoperable, or which recurs following initial treatment, can qualify you for disability benefits. Benign forms of the disease can as well, if they result in such severe limitations that they prevent you from working for a period of one year or are expected to do so.
What chromosome is APC on?
Familial adenomatous polyposis coli is an autosomal dominant hereditary form of colorectal cancer associated with mutations in the adenomatous polyposis coli (APC) gene on chromosome 5.
Where is the APC gene located?
The human APC gene is located on the long (q) arm of chromosome 5 in band q22. 2 (5q22.
What is Carney’s triad?
Carney triad is a rare condition that describes the occurrence of three kinds of endocrine tumors in the same child. The tumors comprising the triad are tumors in the gastrointestinal tract (known as gastrointestinal stromal tumors, or GIST), pulmonary chondromas, and paragangliomas.
What is von Hippel Lindau disease?
Von Hippel–Lindau disease. von Hippel–Lindau disease (VHL), is a rare genetic disorder with multisystem involvement. It is characterized by visceral cysts and benign tumors with potential for subsequent malignant transformation.
Is von Hippel-Lindau disease dominant or recessive?
Von Hippel–Lindau disease is inherited in an autosomal dominant pattern. 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 mutation and produces a faulty VHL protein (pVHL).
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.
How is von Hippel-Lindau disease (VHL) diagnosed?
The diagnosis of von Hippel-Lindau disease can be made based on specific clinical criteria (signs and symptoms), or when molecular genetic testing reveals a change (mutation) in the VHL gene.
