Wilson's disease is an autosomal-recessive disorder of copper metabolism resulting from the absence or dysfunction of a copper-transporting. The disease is mainly seen in children, adolescents and young adults, and is characterized by hepatobiliary, neurologic, psychiatric and ophthalmologic (Kayser-Fleischer rings) manifestations. The deposition of copper in tissues is the cause of virtually all the manifestations of the disease in Liver, Blood, Kidney and Brain. We present here a case study of Wilson’s disease in 12 years old children. [Basappa K et al NJIRM 2013; 4(6) :143-144]
