In addition to diminished PPI, the increased sensitivity of Fabp7-null mice to repeated administrations of MK-801 further links this gene to schizophrenia, because chronic intake of a similar NMDA antagonist, phencyclidine, induces schizophrenia-like symptoms in humans and exacerbates symptoms in chronic stabilized schizophrenic patients [50]. This evidence concerns the gene FABP7 and schizophrenia.
