Wilson Disease Treatment in Singapore

What is Wilson Disease?

Wilson disease is a rare inherited disorder of copper metabolism caused by pathogenic variants in the ATP7B gene. The condition prevents the body from properly transporting and eliminating excess copper, causing copper to accumulate primarily in the liver and, in some patients, the brain, eyes and other organs. Wilson disease can cause liver disease, neurological or movement disorders, psychiatric symptoms and other systemic complications. It is inherited in an autosomal recessive pattern.

What is the Importance of Timely Treatment?

Timely diagnosis and lifelong treatment are important because progressive copper accumulation can cause irreversible liver and neurological damage. Early treatment can reduce copper accumulation, prevent further organ injury and help control existing symptoms. Individuals with severe liver failure or disease that does not respond adequately to medical treatment may require liver transplantation.

What are the Common Symptoms of Wilson Disease?

• Jaundice or yellowing of the skin and eyes
• Abdominal swelling or discomfort
• Fatigue and weakness
• Enlarged liver or spleen
• Abnormal liver function
• Tremors
• Muscle stiffness or dystonia
• Problems with coordination or walking
• Difficulty speaking or swallowing
• Involuntary movements
• Difficulty with handwriting or fine movements
• Mood or behavioural changes
• Depression or anxiety
• Cognitive changes
• Kayser-Fleischer rings around the cornea
• Episodes of hemolytic anemia

Causes and Risk Factors of Wilson Disease

Causes

• Wilson disease is caused by pathogenic variants in both copies of the ATP7B gene, which provides instructions for a copper-transporting protein that incorporates copper into ceruloplasmin and eliminates excess copper through bile.
• Impaired ATP7B function leads to progressive copper accumulation in tissues.

Risk Factors

• Having pathogenic variants in both copies of the ATP7B gene
• Having a sibling or close relative with Wilson disease
• Having parents who are carriers of an ATP7B pathogenic variant
• Family history of unexplained liver disease or neurological symptoms
• Consanguinity in families, which can increase the likelihood of autosomal recessive disorders

Latest Research and Technologies in the Treatment of Wilson Disease in Singapore

Advances in Wilson disease care focus on improving early diagnosis, genetic testing, assessment of copper accumulation and long-term monitoring of treatment response.

• The Leipzig scoring system helps clinicians combine clinical findings, copper-related laboratory results, eye examination findings and genetic results to support diagnosis.
• ATP7B genetic testing can help confirm the inherited cause and identify affected relatives.
• Specialised copper testing, including newer measures such as relative exchangeable copper where available, may support diagnosis and monitoring in selected cases.
• Liver assessment and brain MRI may help evaluate organ involvement when clinically indicated.
• Liver transplantation remains an important treatment option for selected patients with Wilson disease-related acute liver failure or advanced liver disease.

Research into gene-based and other emerging treatments is ongoing. These approaches should not be described as established routine treatments unless their availability and clinical status have been verified. Availability of specific tests and services in Singapore should be confirmed with the treating hospital.
