Wilson's disease is an inherited inborn error of metabolism in which the body cannot process copper.
Wilson's disease is caused by a defect in an enzyme, or special protein. This enzyme normally helps the body get rid of extra copper. The amount of copper in a normal diet is more than the body needs. In people with Wilson's disease, the extra copper cannot be excreted from the body. The copper can damage the liver, brain, kidney, cornea, and other organs.
Wilson's disease is an inherited disorder. The children of parents who carry the gene for the disorder are at risk. The liver disease usually starts between ages 8 and 12, while the brain symptoms occur later in life.
