Introduction:
Wilson's disease is an inherited autosomal recessive disorder of copper metabolism. The prevalence of Wilson's disease in most populations is approximately 1 in 30,000. The risk for offspring is 0.5%. The aim of this study was to establish the frequency of disease among offspring of a cohort of Wilson's disease patients.
Materials And Methods:
In February 2014, our registry included 760 cases of diagnosed Wilson's disease. We selected families in which Wilson's disease was diagnosed in the proband's offspring.
Results:
Between 1957 and 2014, 1,050 relatives of affected members were screened. Wilson's disease in subsequent generations was observed in nine non-consanguineous families, with 12 affected offspring from nine probands.
Conclusion:
We detected a higher (4.08%) than expected (0.5%) frequency of Wilson's disease among proband offspring, which is in accordance with a recent genetic study in the United Kingdom that suggested a higher WD prevalence in the European population.
