Leaky channels make weak muscles: Mutations in the skeletal muscle voltage-gated calcium channel (CaV 1.1) have been associated with hypokalemic periodic paralysis, but how these mutations cause the symptoms of the disorder has always been unclear. In this article the authors describe how they used mice with the CaV 1.1 mutation  to investigate how the mutation causes the features of HypoKPP.
