Wilson's Disease with Neurological Presentation, without Hepatic Involvement in Two Siblings.

Wilson's Disease (WD) is a rare, autosomal, recessive, inborn error of the copper metabolism, which is caused by a mutation in the copper-transporting gene, ATP7B. The presentation is usually neurologic or hepatic, which is seen in 40% of the patients. The diagnosis depends primarily on the clinical features, the biochemical parameters and the presence of the Kayser - Fleischer ring. Here, we are reporting two siblings who were affected by Wilson's disease, with only neurological manifestations, without any hepatic involvement.
