When to see a doctor
If you experience severe or worsening symptoms, seek immediate medical attention. Always consult with a healthcare professional for proper diagnosis and treatment.
Causes & Risk Factors
Several factors can contribute to Wilson's Disease.
Wilson's disease results from inherited mutations in the ATP7B gene located on chromosome 13.
Wilson's disease results from inherited mutations in the ATP7B gene located on chromosome 13. This gene normally produces a protein called copper-transporting ATPase 2, which moves copper from liver cells into bile for elimination from the body. When mutations disrupt this protein's function, copper cannot exit liver cells properly and begins accumulating throughout the body.
The disease follows an autosomal recessive inheritance pattern, meaning a person must inherit two defective copies of the ATP7B gene - one from each parent - to develop the condition.
The disease follows an autosomal recessive inheritance pattern, meaning a person must inherit two defective copies of the ATP7B gene - one from each parent - to develop the condition. Parents who carry one mutated copy are called carriers and typically show no symptoms, but they have a 25% chance of passing the disease to each child if both parents are carriers.
Over 900 different mutations in the ATP7B gene have been identified, explaining why Wilson's disease can vary significantly in its presentation and severity.
Over 900 different mutations in the ATP7B gene have been identified, explaining why Wilson's disease can vary significantly in its presentation and severity. The type and location of mutations influence which organs are most affected and when symptoms first appear. Some mutations primarily impact liver function, while others predominantly affect the nervous system or cause a combination of symptoms across multiple organ systems.
Risk Factors
- Having parents who both carry ATP7B gene mutations
- Family history of Wilson's disease or unexplained liver problems
- Eastern European, Mediterranean, or Middle Eastern ancestry
- Consanguineous parents (related by blood)
- Unexplained neurological symptoms in young adults
- Early-onset liver disease without clear cause
- Hemolytic anemia of unknown origin
- Psychiatric symptoms appearing in teens or young adults
Diagnosis
How healthcare professionals diagnose Wilson's Disease:
- 1
Diagnosing Wilson's disease requires multiple tests because no single test provides a definitive answer.
Diagnosing Wilson's disease requires multiple tests because no single test provides a definitive answer. Doctors typically start with blood tests measuring ceruloplasmin (a protein that carries copper) and serum copper levels. In Wilson's disease, ceruloplasmin is usually low while free copper in the blood may be elevated. However, these levels can overlap with normal ranges, making diagnosis challenging.

The 24-hour urine copper test often provides more reliable information, as people with Wilson's disease excrete much higher amounts of copper in their urine - typically more than 100 micrograms per day compared to the normal range of 15-60 micrograms.
The 24-hour urine copper test often provides more reliable information, as people with Wilson's disease excrete much higher amounts of copper in their urine - typically more than 100 micrograms per day compared to the normal range of 15-60 micrograms. Eye examinations using slit-lamp microscopy can reveal Kayser-Fleischer rings, the golden-brown copper deposits around the corneas that appear in about 90% of people with neurological symptoms.

Genetic testing for ATP7B mutations confirms the diagnosis and helps identify family members who may be carriers or affected.
Genetic testing for ATP7B mutations confirms the diagnosis and helps identify family members who may be carriers or affected. Liver biopsy, while invasive, remains the gold standard for measuring hepatic copper concentration, with levels above 250 micrograms per gram of dry liver weight strongly suggesting Wilson's disease. Brain MRI may show characteristic changes in the basal ganglia and other regions when neurological symptoms are present.
Complications
- Untreated Wilson's disease can cause severe, irreversible damage to multiple organs.
- Liver complications range from mild inflammation to cirrhosis, liver failure, and death.
- The liver may develop fatty deposits, fibrosis, or progress to end-stage disease requiring transplantation.
- Some people experience acute liver failure with rapid deterioration, while others develop chronic liver disease over years.
- Neurological complications include movement disorders, tremors, difficulty walking, and speech problems that may become permanent even with treatment.
- Psychiatric symptoms like depression, personality changes, and cognitive impairment can significantly impact quality of life.
- Eye problems beyond Kayser-Fleischer rings may include cataracts and other vision issues.
- Heart, kidney, and bone problems can also develop, though these complications are less common and usually reversible with proper treatment.
Prevention
- Wilson's disease cannot be prevented since it results from inherited genetic mutations present from birth.
- However, genetic counseling and testing can help families understand their risk and make informed reproductive decisions.
- If both parents are known carriers of ATP7B mutations, each pregnancy has a 25% chance of producing a child with Wilson's disease and a 50% chance of producing a carrier.
- Early detection through family screening represents the most effective preventive strategy.
- Siblings and children of people diagnosed with Wilson's disease should undergo testing even without symptoms, as early treatment prevents organ damage and improves long-term outcomes.
- Screening typically includes ceruloplasmin levels, 24-hour urine copper, eye examinations, and genetic testing when appropriate.
- For families with known Wilson's disease, prenatal testing can detect affected pregnancies through chorionic villus sampling or amniocentesis.
- While this doesn't prevent the condition, it allows families to prepare for early treatment and management.
- Some couples may choose preimplantation genetic diagnosis during in vitro fertilization to select embryos without Wilson's disease mutations.
Treatment for Wilson's disease focuses on removing excess copper from the body and preventing further accumulation.
Treatment for Wilson's disease focuses on removing excess copper from the body and preventing further accumulation. Chelating agents like penicillamine or trientine bind to copper in tissues and help eliminate it through urine. Penicillamine was the first treatment discovered but can cause side effects including kidney problems, bone marrow suppression, and autoimmune reactions. Trientine often works similarly with fewer side effects, making it a preferred first-line treatment for many patients.
Zinc therapy offers an alternative approach by blocking copper absorption in the intestines and promoting its elimination.
Zinc therapy offers an alternative approach by blocking copper absorption in the intestines and promoting its elimination. Zinc acetate or zinc sulfate supplements increase production of metallothionein, a protein that binds copper and prevents its absorption. This treatment works more slowly than chelating agents but has fewer side effects, making it useful for maintenance therapy or treating pregnant women with Wilson's disease.
Dietary modifications support medical treatment by reducing copper intake.
Dietary modifications support medical treatment by reducing copper intake. Patients should avoid foods high in copper including shellfish, nuts, chocolate, mushrooms, and organ meats. Using copper cookware or drinking water from copper pipes should also be avoided. Most people need to follow these dietary restrictions lifelong, though requirements may vary based on individual copper levels and response to treatment.
Severe cases with liver failure may require liver transplantation, which can be curative since the new liver provides normal copper metabolism.
Severe cases with liver failure may require liver transplantation, which can be curative since the new liver provides normal copper metabolism. Physical therapy, occupational therapy, and speech therapy help manage neurological symptoms, while psychiatric treatment addresses mood and behavioral changes. Regular monitoring with blood tests, urine copper measurements, and clinical evaluations ensures treatment effectiveness and allows for dosage adjustments.
Living With Wilson's Disease
Living successfully with Wilson's disease requires consistent medication adherence and regular medical monitoring. Most people take chelating agents or zinc supplements daily for life, and skipping doses can allow copper to reaccumulate quickly. Regular blood tests, urine copper measurements, and clinical evaluations help doctors adjust treatments and catch any problems early.
