A functional framework in patient fibroblasts informs ATP7A variant pathogenicity and identifies p.Q990P as a novel cause of distal motor neuropathy
{{output}}
ATP7A is a P-type ATPase copper transporter and a central component of the intracellular network to maintain copper (Cu) homeostasis, trafficking between the trans-Golgi network (TGN) and the cell periphery in response to intracellular Cu levels. Pathogenic AT... ...
