Among the DEGs, strong evidence of involvement in neurodevelopmental disorders was reported for 15 of them (“definitive” gene list from SysNDD, e.g., PLP1, RGS6, and SCN3A) and moderate evidence for 10 more (“limited” gene list from SysNDD, e.g., UNC13A, NMNAT2, and CHL1). This evidence concerns the gene PLP1 and neurodevelopmental disorder.
