PTPRN2 and autism: Mapping our results to other databases revealed the following set of imprinted genes linked to ASD: <i>OTX1, PRDM16, PTPRN2, B4GALNT4, KCNQ1, KCNQ1OT1, DLGAP2, PLAGL1, GNAS, GRB10</i>, <i>MAGEL2, CDH24,</i> and <i>FBRSL1.</i> Further research on these genes could help understand the contribution of paternal age on the development of autism.
