Figure 1:. Cav-3 macromolecular complex and effects of CAV3 mutations on cardiac repolarization.
CAV3-V37L gain-of-function effects on ICaL and loss-of-function consequences on IKr and IKs are expected to prolong the cardiac action potential, as would other previously reported changes in several ion channels.
