Both functions of ATP7B are dysfunctional in Wilson disease. Copper accumulates in the liver, and ceruloplasmin is secreted in a form that lacks copper and is rapidly degraded in the bloodstream.

Wilson's disease診斷標準:Ceruloplasmin < 20 mg/dL ----->有5-10%病人會在正常範圍24hr urine Cu2+ > 100 microgram ----->最準確hepatic Cu2+ concentration > 250 microgram/g (dry wet)
