Rare mutations in the NRXN2 gene have been identified with ASD (Gauthier et al., 2011).
Molecular Function
This gene encodes a member of the neurexin gene family. The products of these genes function as cell adhesion molecules and receptors in the vertebrate nervous system. These genes utilize two promoters. The majority of transcripts are produced from the upstream promoter and encode alpha-neurexin isoforms while a smaller number of transcripts are produced from the downstream promoter and encode beta-neurexin isoforms.

SFARI Gene score
High Confidence
A study sequenced NRXN2 in 142 ASD patients and found a single truncating mutation in an ASD patient that was inherited from a father with severe language delay (PMID 21424692). This family was also linked to SCZ. Another study found a single patient with autistic traits, dysmorphism, cancer and a de novo deletion involving NRXN2 and other genes (including MEN1) (PMID 21600320).
