Chloride channel protein 2 is a protein that in humans is encoded by the CLCN2 gene.^[5]^[6] Mutations of this gene have been found to cause leukoencephalopathy^[7] and Idiopathic generalised epilepsy (OMIM: 600699),^[8] although the latter claim has been disputed.^[9] CLCN2 contains a transmembrane region that is involved in chloride ion transport as well two intracellular copies of the CBS domain.
