Based on the results from sequencing the genetic material of 54 patients with a previously established diagnosis of WD, 14 patients with suspected presence of this disease and 32 first-degree relatives (100 people in total), 6 people were identified without mutations in the ATP7B gene, 27 patients were identified with heterozygous carriage and 67 patients were identified with a pathogenic mutation. Here, ATP7B is linked to Wilson disease.
