Pearls & Oy-sters: Challenges and Controversies in Wilson Disease.

Wilson disease (WD) is a genetic disorder of copper metabolism caused by variants in the ATP7B gene, which are inherited in an autosomal recessive pattern. Despite all the advances made on pathogenesis, cellular biology, and genetics, to date, WD remains a diagnostic and therapeutic challenge. With this series of cases, we aim to illustrate the main challenges that clinicians may encounter when dealing with patients with WD: the difficulties with clinical diagnosis, the therapeutic management of WD and the indication for advanced therapies, management during pregnancy, and genotype-phenotype correlations.
