This disease is followed through the “Genetic syndromes and other conditions” group.
The VHL gene stops cells from multiplying out of control. When the gene does not work, growths and fluid-filled sacs, called cysts, form in many organs. The growths most often appear at a young age. But symptoms can begin at any age.
Symptoms vary depending on where the growth is.
The diagnosis is made with a genetic test of the VHL gene. Finding a growth typical of VHL also leads to the diagnosis. After diagnosis, regular screening begins even if there are no symptoms.
Small growths are easier to treat. This is why regular MRI, eye, and blood and urine screening is done. Growths are usually removed with surgery; care is taken to save the organ. For growths in the eye, laser or freezing treatment is used. There is also an approved medicine treatment specifically for the disease for some growths. The doctor who follows the disease decides which treatment is suitable.
It is passed on through dominant inheritance. For each child of an affected parent, the chance of passing it on is 1 in 2. Most people get the gene from an affected parent. About one in five have a new change. Genetic testing and counselling are recommended for family members at risk.
