[Copper intoxication decreases lifespan and induces neurologic alterations in Drosophila melanogaster].

Wilson disease is a hereditary disorder caused by mutations of the ATP7B gene, which leads to intoxication with copper as a result of an unbalance of copper homeostasis. The clinical manifestations resulting from this intoxication are related to the affectation of liver and the encephalon in most cases. Several animal models are currently available for the study of the malady.
