Paying the price at the pump: dystonia from mutations in a Na+/K+ -ATPase.
Dystonia is a disorder of involuntary sustained muscle contraction, which usually affects a focal region of the body but may be generalized and results in twisting contorted movements or abnormal postures. Several clinical subtypes of dystonia have been delineated and many have a strong inherited basis. In this issue of Neuron, de Carvalho Aguiar and colleagues report the identification of missense mutations in the gene for the Na+/K+ -ATPase alpha3 subunit (ATP1A3) as a cause of rapid-onset dystonia-parkinsonism ( RDP, DYT12).[1]References
