Relevance to Autism
Several studies have found rare variants in the NLGN4X gene in autism. Association was seen in Finnish and Caucasian population cohorts. However, several studies have found no rare variants in the NLGN4X gene in autistic patients in their cohorts (including Quebec population and IMGSAC cohorts).
Molecular Function
Neuroligins are cell-adhesion molecules at the postsynaptic side of the synapse .
