Wilson disease is a rare genetic disorder characterized by excess copper stored in various body tissues, particularly the liver, brain and corneas of the eyes. The disease is progressive and, if left untreated, it may cause liver (hepatic) disease, central nervous system dysfunction and death. Early diagnosis and treatment may prevent serious long-term disability and life-threatening complications.
Wilson disease is caused by changes (variants) of the ATP7B gene. Inheritance is autosomal recessive.
Treatment is lifelong and aims to reduce the amount of copper that has accumulated in the body and to maintain normal copper levels thereafter.
Wilson disease is a rare genetic disorder that affects the bodyโs ability to process and eliminate copper, leading to copper buildup in vital organs like the liver and brain. While the disease usually starts with liver problems in childhood, many symptoms may not appear until the teenage years or early adulthood.
For many people, especially children, Wilson disease first presents as liver disease. The symptoms can range from mild to severe, including:
Some children may have asymptomatic liver injury, which means they show no symptoms but have abnormal liver tests. Over time, this can lead to cirrhosis scarring of the liver (cirrhosis) or even acute liver failure, a serious condition that requires immediate medical attention.
In teenagers and adults, the disease may shift to affect the brain and nervous system, often presenting with neurological or psychiatric symptoms:
Most people affected with Wilson Disease who have neurological symptoms will also have Kayser-Fleischer rings, which are rusty-brown rings around the corneas of the eyes caused by copper deposits. These can be seen by an ophthalmologist.
Psychiatric symptoms can vary widely and may include:
In most people, psychiatric symptoms appear alongside neurological symptoms or develop within three years of their onset.
Some women (especially young women) present with menstrual and hormonal issues due to liver dysfunction, leading to:
Wilson disease can also lead to other health complications including:
Liver disease is the most common first sign, but some children may also experience neuropsychiatric symptoms.
During adolescence, liver disease can become severe, but neurological and psychiatric symptoms may also develop. Liver failure can occur more frequently in adolescence, particularly in young women.
In adults, neuropsychiatric symptoms tend to dominate, though liver disease is still common. Scarring of the liver (cirrhosis) is present in about 38% of children and 58% of adults at diagnosis.
Females are more likely to present with liver disease, especially in childhood while males more likely to develop neurological symptoms as they age.
As commented before, some people with Wilson disease may not show symptoms for many years or might never develop noticeable symptoms. Many people with Wilson disease are diagnosed because of abnormal liver function tests, even before other symptoms appear.
Wilson disease is caused by changes (variants) of the ATP7B gene, which plays an important role in the movement of excess copper from the liver to the bile to eventually be excreted from the body through the intestines. More than 300 different variants of the ATP7B gene have been identified.
Wilson disease is inherited in an autosomal recessive pattern. Recessive genetic disorders occur when an individual inherits a disease-causing gene variant from each parent. If an individual receives one normal gene and one disease-causing gene variant, the person will be a carrier for the disease, but usually will not show symptoms. The risk for two carrier parents to both pass the gene variant and have an affected child is 25% with each pregnancy. The risk of having a child who is a carrier like the parents is 50% with each pregnancy. The chance for a child to receive normal genes from both parents is 25%. The risk is the same for males and females.
Wilson disease is a rare disorder that affects males and females in equal numbers. The disease is found in all races and ethnic groups. Although estimates vary, it is believed that Wilson disease occurs in approximately one in 30,000 to 40,000 people worldwide. Approximately one in 90 people may be carriers of a gene variant for the disease. Although only about 2,000-3,000 people have been diagnosed in the United States, other affected individuals may be misdiagnosed with other neurological, liver or psychiatric disorders. According to one estimate, there may be 9,000 people affected by Wilson disease in the United States.
Wilson disease may be diagnosed based upon a thorough clinical evaluation, a complete patient history and specialized tests.
Early diagnosis and treatment are essential to prevent permanent damage to the liver, brain and other organs.
Most children with Wilson disease have liver disease, therefore, doctors should consider this diagnosis in any child over one year old who shows signs of liver dysfunction, though it is rare before the age of five.
While neurological symptoms, such as tremors or difficulty speaking, typically appear later in life (around the second or third decade), they can develop as early as six years of age. Wilson disease should also be considered in adolescents with unexplained cognitive or psychiatric issues. Itโs important to identify the disease early, especially because many affected people may show mild symptoms or none during the early stages of the disease.
The diagnosis of Wilson disease involves several steps that include clinical evaluation, specialized blood and urine tests, genetic testing and sometimes a liver biopsy.
Suggested steps for diagnosis include:
Step 1:
Step 2:
Step 3: (if needed)
Additional diagnostic tests may include:
Ultrasound and other non-invasive tools like transient elastography may be used to assess liver damage, including the presence of fibrosis (scarring of the liver).
The exchangeable copper (CuEXC) is a promising new test that measures unbound copper in the blood independently of ceruloplasmin levels. However, it is currently available only in research settings.
As none of the available laboratory tests are completely accurate and specific for Wilson disease and sometimes the symptoms are not present, in 2001, a diagnostic score (known as Ferenci score), based on clinical manifestations, laboratory tests, histology (tissue analysis) and genetics was established and proved to have good diagnostic accuracy, especially in unclear cases.
The Wilson Disease Prognostic Index is used to evaluate patients with acute liver failure and predict the need for a liver transplant (LT). It considers factors like bilirubin levels, liver enzymes, INR (a measure of blood clotting), white blood cell count and albumin.
Since many of the symptoms can overlap with other conditions, a high level of suspicion is necessary, especially in children and adolescents with unexplained liver or neurological issues.
Treatment
Treatment focuses on reducing copper levels to prevent the progression of the disease and reversing symptoms caused by copper buildup in organs like the liver and brain. Early diagnosis and adequate treatment are essential for improving outcomes and preventing severe complications. It is important to understand that treatment is lifelong.
Treatment for Wilson disease depends on the stage of the disease:
Wilson disease is treated using three main types of medications that work by either removing copper from the body or preventing its absorption from food.
A concerning side effect for people treated with either D-penicillamine or trientine is a rapid clinical worsening of neurologic symptoms within months after treatment onset, possibly caused by rapid mobilization of large amounts of copper.
For mild to moderate liver disease, a combination of trientine and zinc is often used for 4-6 months followed by maintenance therapy with either trientine or zinc alone. Penicillamine can also be used but is less preferred due to its side effects.
Regular follow-up is essential to ensure that copper levels remain controlled and to avoid side effects from the medications. Monitoring includes 24-hour urine copper test (measures how much copper is being excreted in the urine), non-ceruloplasmin-bound copper (a blood test that measures the amount of toxic copper not bound to ceruloplasmin), liver function tests to monitor liver health and check for signs of improvement or worsening and urine tests for people on chelating agents like penicillamine or trientine (urine tests are used to detect any protein or blood cells, which could indicate kidney issues).
Stopping the treatment can lead to a rapid buildup of copper and life-threatening complications, so itโs critical for the affected people to adhere to their medication regimen.
By following the treatment plan and adhering to medication, most people affected with Wilson disease can lead healthy and active lives. However, diagnosis is often delayed and there is frequently a lack of adherence to the necessary lifelong treatment. Even in people with clinically stable and well-managed disease, Wilson disease may result in a decreased quality of life.
For people with severe liver failure or acute liver failure, a liver transplant may be the only option for long-term survival. Transplants can restore normal liver function and stop the progression of Wilson disease. However, the need for a liver transplant in neurological cases is controversial and this has to be decided on a case-by-case basis.
The Wilson Disease Association offers updates in treatment and advances as well as many useful resources for patients and health professionals.
The American Association for the Study of Liver Diseases (AASLD) developed recommendations for Wilson disease treatment that are available in the article: entitled: Wilson disease: a summary of the updated AASLD Practice Guidance. Note that this article has many medical terms.
There is ongoing research to find better treatments for Wilson disease, including:
The Wilson Disease Association has designated several Wilson Disease Centers of Excellence that you can see in the following link: Wilson disease centers of excellence.
The Wilson Disease Association has also a Patient Registry Study Patient registries and databases are key instruments to develop clinical research in the field of rare diseases and improve patient care as well as healthcare planning and policy.
