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.
