In a comparative bioinformatic analysis, neuroligin-2 (nlg2) and NMDA receptor 2 (nmdar2) were found to be Category 1 (“high confidence”) genes in the Simons Foundation Autism Research Initiative (SFARI) gene database (https://gene.sfari.org/), meaning they have been clearly implicated in human Autism Spectrum Disorder. Here, NLGN2 is linked to autism.
