Deficiency of serum ceruloplasmin due to an abnormal copper transporter gene characterizes Wilson disease. Urine copper collection may be abnormal. In addition, liver function tests and liver transaminases may be abnormal. Also, check the copper transporter gene in patients in whom Wilson disease is suspected.
