Abstract
There has been some limited progress in the understanding of the basic defect in Wilson disease and the gene concerned has been located to the chromosome region 13q14. Treatment with zinc has emerged as a definite alternative to penicillamine administration and some shortcomings and/or hazards of both forms of therapy have emerged as their modes of action have been studied more carefully. Tetrathimolybdate may have a place in treatment, espacially when rapid complexing of copper is important. Hepatic copper accumulation occurs in a number of cholestatic diseases and they play an important part in pathogenesis and can occasionally lead to neurological toxic effects. Copper overload in the new-born period when biliary excretion of copper is inefficient may establish a vicious cyle of copper accumulation and liver damage in Indian childhood cirrhosis and less frequently in babies in other countries.
