Wilson's disease; Hepatolenticular degeneration
Wilson disease is an inherited disorder in which there is too much copper in the body's tissues. The excess copper damages the liver and nervous system.
Wilson disease is a rare inherited disorder. If both parents carry a defective gene for Wilson disease, there is a 25% chance in each pregnancy that the child will have the disorder.
Wilson disease causes the body to take in and keep too much copper. The copper deposits in the liver, brain, kidneys, and eyes. This causes tissue damage, tissue death, and scarring. The affected organs stop working normally.
This condition is most common in eastern Europeans, Sicilians, and southern Italians, but it may occur in any group. Wilson disease typically appears in people under 40 years old. In children, the symptoms begin to show by age 4.
Symptoms may include:
A slit-lamp eye exam may show:
A physical exam may show signs of:
Lab tests may include:
If there are liver problems, lab tests may find:
Other tests may include:
The gene that causes Wilson disease has been found. It is called ATP7B. DNA testing is available for this gene. Talk to your health care provider or a genetic counselor if you would like to have gene testing performed.
The goal of treatment is to reduce the amount of copper in the tissues. This is done by a procedure called chelation. Certain medicines are given that bind to copper and help remove it through the kidneys or gut. Treatment must be lifelong.
The following medicines may be used:
Vitamin E supplements may also be used.
Sometimes, medicines that chelate copper (such as penicillamine) can affect the function of the brain and nervous system (neurological function). Other medicines under investigation may bind copper without affecting neurological function.
A low-copper diet may also be recommended. Foods to avoid include:
You may want to drink distilled water because some tap water flows through copper pipes. Avoid using copper cooking utensils.
Symptoms may be managed with exercise or physical therapy. People who are confused or unable to care for themselves may need special protective measures.
A liver transplant may be considered in cases where the liver is severely damaged by the disease.
Life-long treatment is needed to control Wilson disease. The disorder may cause fatal effects, such as loss of liver function. Copper can have toxic effects on the nervous system. In cases where the disorder is not fatal, symptoms may be disabling.
Complications may include:
Liver failure and damage to the central nervous system (brain, spinal cord) are the most common and dangerous effects of the disorder. If the disease is not caught and treated early, it can be fatal.
Call your provider if you have symptoms of Wilson disease. Call a genetic counselor if you have a history of Wilson disease in your family and you are planning to have children.
Genetic counseling is recommended for people with a family history of Wilson disease.
