NLGN4X and autism: Table 3 summarises the genes located at the SVs and their corresponding chromosomal banding. The SVs found could be de novo, maternal, or paternal in inheritance. The significance of some important genes implicated in autism, including CNTNAP2, GABRB3, JARID2, NLGN4X, NRXN1, PARK2, SHANK3, and UBE3A, were listed in Table 4 and reviewed in the discussion section of this review.
