NLGN3

A gene on chromosome Xq13.1 that encodes neuroligin 3, a neuronal cell surface protein involved in cell–cell interactions, which forms intercellular junctions by binding to beta-neurexins. It may play role in forming or maintaining synaptic junctions, as well as glia–glia or glia–neuron interactions in the developing peripheral nervous system.
 
Molecular pathology
Defects of NLGN3 have been linked to an increased susceptibility to Asperger syndrome (X-linked type 1) and to autism (X-linked type 1).

The rats mimic specific symptoms of autism spectrum disorder because they are each genetically engineered to lack one of seven genes associated with the autism spectrum disorders: Fmr1, Neuroligin 3, Neurexin 1 alpha, Cav1.
Currently, there is only very limited information available on the etiology and biological basis of the autism spectrum disorders, although a mutation in the neuroligin 3 gene has caught researchers' attention in recent studies.
The neuroligin 3 mutation, an arginine-to-cysteine substitution, was identified in a set of twins and has been shown to result in most of the expressed protein being retained within the endoplasmic reticulum.
