[Research progresses in gene therapy for hepatolenticular degeneration].

Hepatolenticular degeneration, also known as Wilson's disease, is a type of autosomal recessive genetic disorder of copper metabolism. The causative gene, ATP7B, is located on the long arm of chromosome 13 and encodes a P-type ATPase that is involved in copper transport. Pathogenic mutations in the ATP7B gene sequence lead to the diminished or lost function of the ATP7B protein, resulting in pathological copper deposition in organs such as the liver, brain, kidneys, and cornea.
