title: [Wilson disease - factors affecting clinical presentation].
abstract: Wilson disease (WD) is a genetic disorder with copper metabolism disturbances leading to copper accumulation in many organs with their secondary damage. It is caused by mutation in the ATP7B gene on chromosome 13, which encodes ATP-ase 7B involved in copper transport. The age of neurologic symptom onset in WD is 20-30 years, but there is a wide spectrum of disease including: age at onset, clinical signs and treatment efficacy. More than 500 mutations of ATP7B have been described so far, but the WD genotype does not explain the disease variability. Several other factors are suspected to influence WD presentation, including polymorphisms in the genes encoding: apolipoprotein E, prion-related protein, methyltenetetrahydrofolate reductase, Murr1, antioxidant-1, X-linked inhibitor of apoptosis as well as iron metabolism disturbances, gender impact, inflammatory reactions and oxidative stress. The explanation of their significance can change the therapy of WD. The aim of our study was to review and assess the clinical significance of the factors affecting WD presentation.
