We recently demonstrated that ataxia telangiectasia mutated (ATM) directly shapes the development of the GABAergic system. Here, we show for the first time to our knowledge how the abnormal expression of ATM affects the pathological condition of autism. We exploited 2 different animal models of autism, the methyl CpG binding protein 2\u2013null (\n                    <jats:italic>\n                      Mecp2\n                      <jats:sup>y\/\u2013<\/jats:sup>\n                    <\/jats:italic>\n                    ) mouse model of Rett syndrome and mice prenatally exposed to valproic acid, and found increased ATM levels. Accordingly, treatment with the specific ATM kinase inhibitor KU55933 (KU) normalized molecular, functional, and behavioral defects in these mouse models, such as (a) delayed GABAergic development, (b) hippocampal hyperexcitability, (c) low cognitive performances, and (d) social impairments. Mechanistically, we demonstrate that KU administration to WT hippocampal neurons leads to (a) higher early growth response 4 activity on\n                    <jats:italic>Kcc2b<\/jats:italic>\n                    promoter, (b) increased expression of Mecp2, and (c) potentiated GABA transmission.
