Translational research investigations on ATP7A: an important human copper ATPase.

In more than 40 years since copper deficiency was delineated in pediatric subjects with Menkes disease, remarkable advances in our understanding of the clinical, biochemical, and molecular aspects of the human copper transporter ATP7A have emerged. Mutations in the gene encoding this multitasking molecule are now implicated in at least two other distinctive phenotypes: occipital horn syndrome and ATP7A-related isolated distal motor neuropathy. Several other novel inherited disorders of copper metabolism have been identified in the past several years, aided by advances in human gene mapping and automated DNA sequencing. In this paper, I review the history and evolution of our understanding of disorders caused by impaired ATP7A function, and outline future challenges.
