Remarkably, 14 of these were found to be in common with the 20 genes identified in the present work (MECP2, WAC, GRIN2B, STXBP1, PTEN, TCF4, POGZ, DYRK1A, ADNP, AUTS2, CHD2, SYNGAP1, DDX3X, UBE3A), but it should also be noted that, unlike the present study, they included cases of NDD, developmental disorder and intellectual disability, as a broader phenotype [18]. The gene discussed is WAC; the disease is Intellectual disability.
