Wilson's disease, also known as hepatolenticular degeneration, is a rare genetic disorder characterized by excessive accumulation of copper in various organs such as the liver, brain and kidneys. The condition is caused by a mutation in the ATP7B gene, which plays a vital role in the transport of copper in the body. Synonyms for Wilson's disease include copper storage disease, hepatic copper toxicity, and copper metabolism disorder. Some additional terms that may be used to describe the condition include Kayser-Fleischer rings, Wilson's syndrome, and auto-brewery syndrome. While there is no cure for Wilson's disease, treatments such as medication and dietary changes can help manage symptoms and prevent further damage to the body.
