For example, a recent genome-wide association study [122] of 76,755 individuals with schizophrenia highlights the importance of GRIN2A (which encodes a subunit of the NMDA receptor), while a recent meta-analysis of whole exomes [123] emphasises the role of GRIN2A, as well as GRIA3 (which encodes a subunit of the AMPA receptor). This evidence concerns the gene GRIN2A and schizophrenia.
