Wilson disease (WD; Online Mendelian Inheritance in Man [OMIM] accession number #277900) is an autosomal recessive copper storage disease resulting from biallelic pathogenic mutation in the ATP7B gene, which encodes the P-type adenosine triphosphatase (ATPase), ATPase-7B (OMIM number *606882) (Ala et al. 2007). This evidence concerns the gene ATP7B and Wilson disease.
