NLGN1 and neurodevelopmental disorder: This finding supports previous work from multiple model organisms which found that inactivating neurodevelopmental disorder risk genes commonly impaired habituation of response probability (Fenckova et al., 2019; McDiarmid et al., 2020a,b) and that impairments in habituation caused by inactivation of the ASD risk gene ortholog neuroligin (NLGN1/2/3/X•nlg-1) could be partially rescued with adult re-expression (McDiarmid et al., 2020a,b).
