What is Wilson Disease
Wilson Disease (also called Wilson’s disease or hepatolenticular degeneration) is a rare inherited genetic disorder that causes excessive copper to accumulate in the body, particularly in the liver, brain, eyes, and sometimes other organs. If untreated, the copper buildup becomes toxic and can lead to severe liver damage, neurological problems, and life-threatening complications.
It affects about 1 in 30,000 people worldwide and is present from birth, but symptoms often appear between ages 5–35 (though they can start earlier or later).
What Causes Wilson Disease?
- Caused by mutations in the ATP7B gene (autosomal recessive inheritance).
- You need two mutated copies of the gene (one from each parent) to develop the disease.
- The ATP7B gene normally helps the liver excrete excess copper into bile for removal from the body. When defective, copper builds up instead.
Common Symptoms
Symptoms vary widely depending on which organs are affected and can develop gradually:
Liver-related (hepatic) — Often the first sign, especially in children/teens:
- Fatigue, jaundice (yellowing of skin/eyes)
- Abdominal swelling or pain
- Swelling in legs/ankles (edema)
- Easy bruising or bleeding
- In severe cases: acute liver failure
Neurological/Psychiatric — More common in young adults:
- Tremors, muscle stiffness, or involuntary movements
- Difficulty speaking or swallowing
- Coordination/balance problems (ataxia)
- Personality changes, depression, anxiety, or psychosis
- Dystonia or Parkinson-like symptoms
Eye signs:
- Kayser-Fleischer rings — Golden-brown copper deposits in the cornea (visible on eye exam; classic but not always present).
Other: Kidney issues, anemia, arthritis, or heart problems in some cases.
Diagnosis
No single test is definitive — doctors use a combination:
- Blood tests (low ceruloplasmin, low or high copper levels)
- 24-hour urine copper collection (elevated)
- Eye exam (slit-lamp) for Kayser-Fleischer rings
- Liver biopsy (copper quantification)
- Genetic testing for ATP7B mutations
- Scoring systems (e.g., Leipzig score) to combine findings.
Treatment and Management
Wilson Disease is highly treatable, especially if diagnosed early. Lifelong treatment is required:
- Chelating agents — Penicillamine or trientine: Bind copper and increase urinary excretion.
- Zinc therapy — Blocks intestinal copper absorption (often used for maintenance or milder cases).
- Tetrathiomolybdate — In some cases for neurological symptoms.
- Low-copper diet (avoid shellfish, nuts, chocolate, liver, mushrooms).
- In advanced liver failure: Liver transplant (curative in many cases).
With proper treatment, most people live normal, full lives. Early diagnosis before permanent damage is key.
Note: Wilson Disease is distinct from other copper-related or liver disorders. It is not contagious and carriers (one mutated gene) are usually asymptomatic.
