ABSTRACT
Glutamate is a necessary excitatory neurotransmitter in human nervous system, which runs a biological function by binding with corresponding receptors. Psychiatric diseases occur when genes which encode receptors become dysfunctional. The authors have reviewed related literature and summarized the association between schizophrenia and glutamate receptor gene SNPs such as rs11146020 in GRIN1, 366C/G in GRIN2B, and rs1468412 in GRM3, etc. Due to controversial results in various studies, it is hypothesized that schizophrenia are complicated polygenic inherited diseases. Some sites such as 366C/G, 2664C/T and rs1408766 (C/T) possess with valuable genetic polymorphisms and might potentially contribute to personal identification and paternity testing. Studies in this field may have a potential significance in forensic psychiatry practice.
