ATP7B and Wilson disease: Taking into account the patient’s family history, especially with the reference to his father’s diagnosis of WD, we screened the patient’s copper biochemistry and MRI in the presence of the typical manifestations of WD, and without performing a WES to test for the presence of the ATP7B gene variant in the patient, it can be confirmed that the patient has achieved a Leipzig score of 4, with 1 point for low copper cyanophorin, 2 points for high copper excretion, and 1 point for neurologic signs and symptoms, and that the diagnosis of WD has been adequately based.
