Description

Mutations or loss of the NRXN1 gene, located on chromosome 2, is associated with severe brain disorders, autism, schizophrenia, and developmental delay. NRXN1 binds to neurolignins bridging the synaptic cleft. Alternatively spliced NRXN1 and NRXN3 influence the expression of NMDA and AMPA receptors.
