K+/Cl- cotransport is implicated not only in regulatory volume decrease, but also in transepithelial salt absorption, renal K+ secretion, myocardial K+ loss during ischemia and regulation of neuronal Cl- concentration. Four genes (SLC12A4-7) encode the K+/Cl- cotransporters KCC1-4 respectively. Cotransport of K+ and Cl- is electroneutral with a 1:1 stoichiometry. These cotransporters function as homomultimers or heteromultimers with other K+/Cl- cotransporters. SLC12A6 encodes KCC3 which is highly expressed in heart, brain, spinal cord, kidney, muscle, pancreas and placenta. Defects in SLC12A6 are a cause of agenesis of the corpus callosum with peripheral neuropathy (ACCPN; MIM:218000), a autosomal recessive disease characterised by severe progressive sensorimotor neuropathy, mental retardation, dysmorphic features and variable degree of agenesis of the corpus callosum (Howard et al. 2002, Dupre et al. 2003, Salin-Cantegrel et al. 2011).
