METHODS： Patients with an established diagnosis of Wilson disease but normal ceruloplasmin blood levels were chosen for our study （n = 14）. Patients with two known disease-causing mutations in the ATPTB gene were not included. The three exons of the human MURR1 gene were sequenced after amplification of the genomic DNA by polymerase chain reaction. RESULTS： Our study did not reveal any mutations leading to an amino acid change in the MURR1 sequence of Wilson disease patients. A polymorphism at 472 bp of the coding sequence could be confirmed. CONCLUSION： The MURRI gene plays no role in the pathogenesis of Wilson disease patients with normal serum ceruloplasmin levels.展开更多
