The pathophysiology of neuropsychiatric disorders like schizophrenia is still poorly understood, although evidence strongly suggests that hypofunction of dopamine receptor and NMDAR and dysfunction of potassium channels play central roles (Stephan et al., 2006; Corti et al., 2011; Vukadinovic and Rosenzweig, 2012). The gene discussed is KCNA3; the disease is schizophrenia.
