Definition

Heterozygous state for Wilsons disease; A rare autosomal recessive disease characterized by the deposition of copper in the BRAIN; LIVER; CORNEA; and other organs; Clinical features include LIVER CIRRHOSIS; LIVER FAILURE; SPLENOMEGALY; TREMOR; bradykinesia; DYSARTHRIA; CHOREA; MUSCLE RIGIDITY; Kayser-Fleischer rings (pigmented corneal lesions); ATAXIA; and intellectual deterioration; Hepatic dysfunction may precede neurologic dysfunction by several years; (From Adams et al, Principles of Neurology, 6th ed pp969-71)Wilson"s disease was first described by Dr Wilson in 1912; It is an autosomal recessive disorder of copper metabolism, characterized by accumulation of copper which is toxic for cells; Its prevalence is 1/30,000; The gene responsible, ATP7B, was mapped to chromosome 13; It encodes a protein belonging to the P-type ATPases family; This protein is a copper transporter necessary for excretion of copper into the bile as well as its incorporation into ceruloplasmin (plasma transporter protein); some 20% of Carrier or heterozygote patients have low ceruloplasmin; The disease is mainly characterized by hepatic and neuropsychiatric symptoms: Association of low ceruloplasmin level (<20mg/dl) and Kayser Fleicher ring is sufficient to establish the diagnosis for homozygous state, for those who present with ceruloplasmin levels > 20mg/dl), liver biopsy with quantification of copper should be performed; ----[Orphanet editorial team -April 2003]----
