WebNational Center for Biotechnology Information WebAbstract. The field of channelopathies is a newly recognized group of disorders named after the site of their molecular defects--voltage- and ligand-gated ion channels. While voltage-gated ion channel mutants have been recognized for some time in organisms such as Drosophila, the first channelopathy in humans was reported within the last decade.
