Examples of such genes include: GABRA5, GABRA3, GABRG3, UBE3A, E2F1, PLCB1, PMP22, AADAT, MAPK3, NRXN1, NRG3, DPP10, UQCRC2, USH2A, NECAB3, CNTN4, LINGO2, IL1RAPL1, STXBP5, DOC2A, and SNRPN. Of these genes, E2F1, AADAT, NECAB3, and IL1RAPL1 are not found in the Autism Chromosome Rearrangement Database (http://projects.tcag.ca/autism/), suggesting that they may be novel ASD risk genes. This evidence concerns the gene GABRA5 and autism.
