AI Summary Wilson's disease is a rare inherited disorder in which an ATP7B gene change lets copper build up in the liver, brain, and other organs. Symptoms can include jaundice, fatigue, tremor, and mood changes, though some people have none for years. Doctors combine blood, urine, eye, biopsy, and genetic tests to diagnose it. Lifelong chelation or zinc therapy controls copper, and a low-copper diet supports care. Relatives of diagnosed people should be screened.
Medically reviewed.
Wilson's disease is a rare inherited disorder that keeps the liver from removing excess copper from the body; copper builds up in the liver and, over time, the brain and other organs. It often causes no symptoms for years, though liver enzyme changes, jaundice, or neurologic and psychiatric symptoms such as tremor or mood changes may develop. People with a sibling or parent diagnosed with Wilson's disease are at higher risk of also carrying the ATP7B gene mutation. Left untreated, Wilson's disease is fatal, but lifelong treatment with chelation medication or zinc therapy allows most people to live full, normal lives.

About Wilson's disease
Wilson's disease is a rare, inherited disorder of copper metabolism caused by mutations in the ATP7B gene, which normally helps the liver excrete excess copper into bile. When ATP7B does not work properly, copper builds up in the liver and, over time, spills into the bloodstream and deposits in the brain and other tissues.
The disease is autosomal recessive: a person needs a mutated copy of the gene from both parents to develop Wilson's disease. Someone with only one mutated copy is a carrier and does not develop symptoms. Many people diagnosed with Wilson's disease have no known family history of the condition, so a new diagnosis in a family is common.
Most people are diagnosed between ages 5 and 35, though the disease can appear earlier or later. Liver disease is generally the most common presentation in childhood, while adults are more likely to first show neurologic or psychiatric symptoms.
Because copper accumulates gradually, Wilson's disease can be present for years before it causes noticeable problems. Left untreated, it can progress to serious liver damage or life-threatening complications, but lifelong treatment that controls body copper allows most people to live full, normal lives.
How Wilson's disease may feel
Wilson's disease can stay silent for years while copper builds up. When symptoms appear, they depend on whether copper is mainly affecting the liver, the nervous system, or both.
Getting checked
Wilson's disease is diagnosed using a combination of blood tests, a 24-hour urine test, an eye exam, and sometimes liver biopsy or genetic testing. No single test confirms the diagnosis on its own.
No single test confirms Wilson's disease — doctors combine eye exams, blood and urine copper measures, and sometimes liver biopsy or genetic testing.
Care & management
Treatment for Wilson's disease focuses on removing excess copper already stored in the body and then preventing it from building up again. Because the condition is lifelong, treatment continues for life, even after copper levels return to normal.
Initial treatment for symptomatic patients typically starts with a copper-chelating medication — penicillamine or trientine — which binds excess copper so it can be excreted in the urine. Once copper levels are controlled, some patients move to zinc acetate, which blocks the intestine from absorbing dietary copper, as maintenance therapy. Regular blood work and 24-hour urinary copper testing monitor whether treatment is working and whether a patient is staying on it.
Chelation therapy (penicillamine or trientine) removes copper already stored in tissues by binding it so the kidneys can excrete it in urine. Zinc acetate works differently: it blocks new dietary copper from being absorbed in the gut. Doctors choose or combine therapies based on a patient's age, symptoms, disease severity, and tolerance of each medication.
If Wilson's disease has caused severe liver damage or acute liver failure, a liver transplant may be necessary. A transplant replaces the liver and corrects the underlying copper-processing defect, since the new liver carries a working ATP7B gene.
Wilson's disease requires lifelong treatment. With early diagnosis and consistent chelation or zinc therapy, most people can lead a very normal life, but stopping treatment allows copper to build up again.
Wilson's disease is caused by inherited mutations in the ATP7B gene, not by diet, lifestyle, or anything a person did. Understanding how it is inherited helps families know who else may be at risk.
Wilson's disease occurs only when a person inherits a mutated ATP7B gene from both parents. Many people diagnosed have no known family history, so genetic testing of relatives after a diagnosis is often recommended.
When to get checked
Wilson's disease often develops silently, and untreated copper buildup can be fatal. Knowing when to seek evaluation can lead to an earlier diagnosis and a much better outlook.
Talk with a healthcare provider if you have unexplained liver enzyme elevations, unexplained tremor or coordination problems, new changes in mood or behavior, jaundice, or a sibling or parent diagnosed with Wilson's disease. Because the condition is inherited, first-degree relatives of a diagnosed patient should be screened even without symptoms.
Wilson's disease is fatal unless detected early and treated appropriately. Because copper builds up gradually and symptoms can be subtle or mistaken for other conditions, delayed diagnosis allows more copper to accumulate in the liver and brain, increasing the risk of permanent damage.
A hepatologist typically leads diagnosis and treatment of liver-related Wilson's disease, often working alongside a neurologist when neurologic or psychiatric symptoms are present. Because Wilson's disease affects multiple organ systems, a multidisciplinary team approach is recommended.

Eating & liver health
Diet is a supportive part of managing Wilson's disease alongside medication, not a replacement for it. Because the underlying problem is the body's inability to clear copper, people with Wilson's disease are generally advised to limit foods that are naturally high in copper.
Copper-rich foods to reduce include liver and other organ meats, shellfish, nuts, mushrooms, legumes, and chocolate. Drinking water should be tested or purified if there is any concern about its copper content, since well water and old copper pipes can add to the body's copper load.
These dietary changes work alongside, not instead of, chelation or zinc therapy. Talk with your care team about how strict a low-copper diet needs to be for your stage of disease and treatment plan.

Common questions
Wilson's disease is a rare inherited disorder that prevents the body from clearing extra copper. Normally, the liver moves extra copper into bile, and the body removes it. In Wilson's disease, copper stays in the body instead. It builds up in the liver first and later in the brain and other organs. Over time, this can cause liver damage and neurologic or psychiatric symptoms. The disease affects about 1 in 30,000 people worldwide.
Yes. A person develops Wilson's disease only after inheriting a mutated copy of the ATP7B gene from both parents. This pattern is called autosomal recessive inheritance. A person with just one mutated copy is a carrier and does not develop symptoms. Many people with Wilson's disease have no known family history, because carrier parents usually feel healthy. Because the disease is inherited, doctors often recommend that brothers, sisters, and other close relatives of a diagnosed person be screened.
Doctors combine several tests, because no single test confirms Wilson's disease. These include a ceruloplasmin blood test, a 24-hour urine copper test, and an eye exam for Kayser-Fleischer rings, the golden-brown rings around the cornea. Doctors may also measure copper in a liver biopsy sample or test for ATP7B gene mutations. Ceruloplasmin can be low-normal in people with active liver disease, so it cannot rule out the disease alone. Most people are diagnosed between ages 5 and 35, but the disease can appear earlier or later.
Symptoms depend on where copper builds up, and some people have none for years. Liver-related symptoms include fatigue, poor appetite, abdominal pain, and jaundice, which is yellowing of the skin and eyes. Neurologic and psychiatric symptoms include tremor, muscle stiffness, trouble with coordination, speech, or swallowing, and changes in mood or behavior. Vomiting blood or fluid buildup in the legs or abdomen may signal more advanced disease and needs prompt medical attention.
Yes, and many people diagnosed early live a very normal life. Treatment lasts a lifetime. It usually starts with a copper-chelating medication, penicillamine or trientine, which binds extra copper so the body can remove it in urine. Some people later move to zinc, which blocks the gut from absorbing copper from food. Regular checks, such as liver tests, 24-hour urine copper, and blood counts, show whether treatment is working. Stopping treatment lets copper build up again, so take medicine as prescribed.
