Aim: To analyze our Wilson disease patient cohort (n=106) for alterations in the gene coding for MURR1.
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 ATP7B 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 MURR1 gene plays no role in the pathogenesis of Wilson disease patients with normal serum ceruloplasmin levels.
