Abstract

Wilson’s disease (WD) is an autosomal recessive disease caused by mutations in the ATP7B gene, which plays a fundamental role in copper metabolism, leading to the accumulation of copper in the liver and other vital organs. Major functions of ATP7B are the incorporation of copper into apoceruloplasmin and the excretion of copper into bile. From simple asymptomatic elevation of liver enzymes to acute liver failure, as well as chronic hepatitis, portal hypertension may be the initial presentation of this disease. Approximately 800 different mutations of the ATP7B gene have been recognized. WD has wide phenotypic disease expressions. Genotypic expression does not always correlate with phenotypic disease expression or disease severity. Environmental and epigenetic factors may play a role in disease expression. No single test is diagnostic for WD. Initial testing includes ocular slit-lamp examination, 24-hour urinary copper excretion, and serum ceruloplasmin. The Leipzig scoring system for diagnosis is widely used. Relative exchangeable copper is the new noninvasive biomarker for WD. It gives a quick result before awaiting genetic testing. Timely diagnosis of WD is important, as it can halt the clinical progression of the liver and neurological disease. D-penicillamine and trientine remain the main chelators for WD treatment. Patients need lifelong chelation therapy until liver transplantation. Research on new treatment modalities, such as methanobactin, is ongoing for further human use. This review discusses the genetic aspects of WD, copper metabolism, a new diagnostic method, and a research molecule for future management of WD.

Core Tip: Wilson’s disease (WD) is an autosomal recessive disease caused by mutations in ATP7B gene which has a fundamental role in copper metabolism, leading to accumulation of copper in the liver and other vital organs. Major functions of ATP7B are incorporation of copper into apoceruloplasmin and the excretion of copper into bile. From simple asymptomatic elevation of liver enzyme to acute liver failure, chronic hepatitis, portal hypertension may be the initial hepatic presentation of this disease. No single test is diagnostic for WD. Initial testing includes ocular slit-lamp examination, 24-hour urinary copper excretion and serum ceruloplasmin. Leipzig scoring system for diagnosis is used widely. Relative exchangeable copper is the new non-invasive biomarker for WD diagnosis with the highest sensitivity and specificity. Patients need lifelong chelation therapy until liver transplantation.
