These proteins are expressed in the trans-Golgi network that guides copper to intracellular compartments, and in copper excess, it relocates copper to the plasma membrane to pump it out from the cells. 2 The intracellular copper transport is regulated by 2 P type ATPase copper transporters ATP7A and ATP7B.
1,2 About 5%-10% of the patients present with 'atypical Menkes disease' characterized by longer survival, cerebellar ataxia, and developmental delay. Other ATP7A mutations have been linked to juvenile occipital horn syndrome and adult-onset hereditary motor neuropathy. Menkes disease is an X-linked multisystem disorder with epilepsy, kinky hair, and neurodegeneration caused by mutations in the copper transporter ATP7A.
