    Voltage-gated ion channels (VGICs) are associated with hundreds of human diseases. To date, 3D structural models of human VGICs have not been reported. We developed a 3D structural integrity metric to rank the accuracy of all VGIC structures deposited in the PDB. The metric revealed inaccuracies in structural models built from recent single-particle, non-crystalline cryo-electron microscopy maps and enabled the building of highly accurate homology models of human Ca v channel α 1 subunits at atomic resolution. Human Ca v Mendelian mutations mostly located to segments involved in the mechanism of voltage sensing and gating within the 3D structure, with multiple mutations targeting equivalent 3D structural locations despite eliciting distinct clinical phenotypes. The models also revealed that the architecture of the ion selectivity filter is highly conserved from bacteria to humans and between sodium and calcium VGICs.
