Phenotypic convergence of Menkes and Wilson disease
Menkes disease is an X-linked multisystem disorder with epilepsy, kinky hair, and neurodegeneration caused by mutations in the copper transporter ATP7A. Other ATP7A mutations have been linked to juvenile occipital horn syndrome and adult-onset hereditary motor neuropathy.1,2 About 5%-10% of the patients present with "atypical Menkes disease" characterized by longer survival, cerebellar ataxia, ...
متن کاملMolecular pathogenesis of Wilson and Menkes disease: correlation of mutations with molecular defects and disease phenotypes.
The trace metal copper is essential for a variety of biological processes, but extremely toxic when present in excessive amounts. Therefore, concentrations of this metal in the body are kept under tight control. Central regulators of cellular copper metabolism are the copper-transporting P-type ATPases ATP7A and ATP7B. Mutations in ATP7A or ATP7B disrupt the homeostatic copper balance, resultin...
متن کاملSolution structures of the actuator domain of ATP7A and ATP7B, the Menkes and Wilson disease proteins.
ATP7A and ATP7B are two human P(1B)-type ATPases that have a crucial role in maintaining copper(I) homeostasis. Among the various domains of these enzymes, one, called the Actuator or A-domain, has a regulatory function and is required for the phosphatase step of the catalytic cycle (dephosphorylation of the intermediate formed during ATP hydrolysis). Here we report the solution structures of t...
متن کاملRetinal localization and copper-dependent relocalization of the Wilson and Menkes disease proteins.
PURPOSE Menkes and Wilson diseases are associated with retinal degeneration. The Menkes and Wilson genes are homologous copper transporters, but differences in their expression pattern lead to different disease manifestations. To determine whether the Wilson and Menkes genes may act locally in the retina, this study was undertaken to assess retinal Wilson and Menkes expression and localization....
متن کاملMenkes' disease: case report.
Menkes disease is a rare neurodegenerative disorder due to an intracellular defect of a copper transport protein. We describe a 7 months male patient who presented with seizures, hypoactivity and absence of visual contact. The investigation disclosed pilli torti and thrycorrexis nodosa in the hair, low serum levels of both copper and ceruloplasmin, brain magnetic resonance study showed atrophy ...
