Please read this first. This guide is a companion to your medical team, not a replacement, and it is not medical advice. Everything here is tied to published research. If something you expected is not here, it almost always means we have not mapped a source for it yet, not that it is unknown to medicine. Wilson disease is an early, growing map, so it will look incomplete on purpose: we would rather show less and have every line be something you can check than fill the page with claims we cannot stand behind. For anything about your own situation, your clinicians hold the full picture. How this guide is built and why.

What's Wilson disease?

Wilson disease is an inherited condition caused by changes in the ATP7B gene that disrupt how the body handles copper, so copper builds up and damages organs such as the liver and brain.

Autosomal recessive inheritance

Wilson disease is passed on in an autosomal recessive pattern: a person is affected only when they inherit a changed copy of ATP7B from both parents.

Treatment and management

What the research describes, not a recommendation. Treatment decisions belong with your clinician.

This covers treatments that appear in the published research mapped here. Investigational and experimental therapies are not included, so their absence is a boundary of this map, not a sign they do not exist.

Penicillamine

Penicillamine is a copper-binding (chelating) medicine used to treat Wilson disease by helping the body remove excess copper.

Used to help with: Wilson disease.

Zinc

Zinc reduces how much copper the gut absorbs from food. It is used to treat Wilson disease, often for long-term maintenance after copper levels are brought down.
