Searching results revealed that mutations of 7 among these 42 genes (Dlg4, Eif4g1, G3bp2, Ntrk2, Rap1gap, Psmd6 and Cpeb4, as shown in Fig. 4F) are associated with autism cases and Dlg4 (encoding PSD-95 protein) and Eif4g1 (encoding eIF4G1 protein) are reported with the highest numbers of autism cases (Fig. 4F). This evidence concerns the gene DLG4 and autism.
