We also identified additional genes that were decreased by at least one of the schizophrenia models examined, including slc6a1 and slc32a1, two genes that encode GABAergic transporters, and slc12a5, the gene for the potassium-chloride cotransporter 2, which regulates intracellular chloride levels and thus GABAergic inhibition. This evidence concerns the gene SLC6A1 and schizophrenia.
