Abstract
Wilson's disease is a treatable inherited disorder of copper metabolism. Established treatments include the use of oral chelating agents and the establishment of a minimum copper diet, although prognosis mainly depends on the extent of liver or nervous system damage present before treatment. Once irreversible damage has occurred, the effect of these treatments is diminished and the patient's quality of life compromised. Therefore, the establishment of a mass screening system able to detect Wilson's disease patients presymptomatically has been discussed. Recently, a monoclonal antibody specific to holoceruloplasmin has been developed. This antibody was used in a nationwide screening trial of 126,810 newborn infants, but no Wilson's disease patients were identified. However, three patients out of 24,165 were diagnosed with Wilson's disease using this specific antibody in a screening performed during the period from late infancy to elementary school. The age of 3 years is thought to be the best point for Wilson's disease mass screening. In this paper, a review of mass screening for Wilson's disease in Japan using a specific monoclonal antibody to holoceruloplasmin is presented.
