“…The transcription factor, myelin transcription factor 1 like (Myt1l), has been implicated in brain disorders including ASD, intellectual disability (ID), and schizophrenia; its gene deletion is more frequently associated with ASD and ID, whereas its gene duplication is associated with schizophrenia (Al Tuwaijri and Alfadhel, 2019;Blanchet et al, 2017;Bonaglia et al, 2014;Carvalho et al, 2021;Coursimault et al, 2022;D'Angelo et al, 2018;de Ligt et al, 2012;De Rocker et al, 2015;De Rubeis et al, 2014;Doco-Fenzy et al, 2014;Iossifov et al, 2014;Loid et al, 2018;Mayo et al, 2015;Meyer et al, 2012;Rio et al, 2013;Satterstrom et al, 2020;Stevens et al, 2011;Tu et al, 2014;Vlaskamp et al, 2017;Wang et al, 2016;Wang et al, 2020;Windheuser et al, 2020) (reviewed in Coe et al, 2019;Mansfield et al, 2020). Myt1l strongly drives the direct conversion of fibroblasts to neurons (Lujan et al, 2012;Marro et al, 2011;Pang et al, 2011;Pfisterer et al, 2011;Son et al, 2011;Torper et al, 2013;Vierbuchen et al, 2010;Xu et al, 2015) and promotes neuronal differentiation by repressing somatic lineage programs, but not the neuronal lineage program (Blanchet et al, 2017;Kepa et al, 2017;Kim et al, 1997;…”
