Wilson disease is an inherited autosomal recessive disorder of hepatic copper metabolism leading to copper accumulation in hepatocytes and in extrahepatic organs such as the brain and the cornea. Originally Wilson disease was described as a neurodegerative disorder associated with cirrhosis of the liver. Later, Wilson disease was observed in children and(More)
Injection into rabbits of radioactive ceruloplasmin from which sialic acid had been removed enzymatically resulted in a rapid disappearance of the asialoceruloplasmin from the seruni and its appearance in parenchymal cells, but not in Kupffer cells, of the liver. The rapidity of this transfer was dependent upon the presence of intact galactose residues as(More)
The pathogenic agent of both Wilson disease (WD) and non-Indian childhood cirrhosis (which we term idiopathic copper toxicosis, or ICT) is copper accumulating to excess in the liver. Inheritance of a pair of alleles of an autosomal recessive gene on chromosome 13 is necessary and sufficient to cause such copper accumulation in WD; reducing the dietary(More)
We studied the mechanisms by which excess copper exerts, and zinc mitigates, toxic effects on HepG2 cells. Survival and cell growth were reduced in media containing greater than 500 microM copper chloride for 48 h; LD50 was 750 microM. At 1,000 microM copper for 1 h, there was a general reduction of protein synthesis, and no recognizable changes in cellular(More)
Wilson disease (WD) is an autosomal recessive disorder characterized by toxic accumulation of copper in the liver and subsequently in the brain and other organs. On the basis of sequence homology to known genes, the WD gene (ATP7B) appears to be a copper-transporting P-type ATPase. A search for ATP7B mutations in WD patients from five population samples,(More)
Penicillamine is known to be effective therapy for Wilson's disease. However, the clinical consequences of the abrupt and permanent withdrawal of penicillamine have not been investigated. We studied 11 patients who stopped their own treatment after having been treated successfully with penicillamine (1 to 2 g per day) for periods of 3 to 19 years. Eight(More)
