Excess copper in the liver is toxic in humans and other mammals, and may lead to acute or chronic hepatitis, steatohepatitis, acute liver failure, cirrhosis and death. Of the several human copper storage diseases that have been described, the molecular basis of only Wilson disease is understood with the discovery of the Wilson disease gene (ATP7B) in 1993. The therapeutic success using oral copper chelating agents and zinc therapy make Wilson disease one of the few treatable genetic metabolic liver diseases. In cases with a fulminant presentation or advanced disease at diagnosis, copper chelation is ineffective and liver transplantation may be lifesaving. Indian Childhood Cirrhosis (ICC) has been defined as a copper-storage disorder precipitated by increased copper intake which affects young children primarily of Indian descent, and which progresses to cirrhosis and death before age three to four years without treatment. Children from North America, Asia, Austria, Germany and other countries have been described with a similar condition, which has been termed idiopathic copper toxicosis (ICT). Several newer disorders of hepatic copper metabolism have been recently described.
