项目摘要

Project Summary/Abstract Neurodevelopmental disorders are common, debilitating disorders including autism, intellectual disability, and perhaps even schizophrenia. Recent genetic findings have identified mutations in multiple genes in various cellular pathways as genetic causes of rare neurodevelopmental disorders including autism spectrum disorders, intellectual disability, and others. This proposal will characterize a novel genetic mouse model, already generated by our laboratory and breeding in our laboratory, to delineate the function of a relatively understudied disease gene in the brain. Specifically, the proposal will be on a gene implicated in a well-defined neurodevelopmental disorder. We propose to obtain preliminary behavioral data in this mouse model on multiple ID-related, ASD-related, and control behavioral tasks. In parallel, we will obtain preliminary single nucleus RNA-seq transcriptomics data and perform preliminary analyses while also examining a specific chromatin modification that we predict will be altered in the genetic mutant mouse model. These unbiased, preliminary, experiments will identify novel downstream targets in mammalian brain, elucidate behavioral outcome measures for future studies, and generate new hypotheses anticipated to lead to future potential therapeutic strategies.

项目摘要/摘要神经发育障碍是常见的，使人衰弱，包括自闭症，智力残疾和也许甚至精神分裂症。最近的遗传发现已经确定了各种基因的突变细胞途径是罕见神经发育障碍（包括自闭症谱系）的遗传原因疾病，智力残疾和其他人。该建议将表征一个新型的遗传小鼠模型，我们的实验室已经产生并在我们的实验室繁殖，以描述相对的功能大脑中研究的疾病基因。具体而言，该提案将基于与明确定义的基因神经发育障碍。我们建议在此鼠标模型中获得初步行为数据多个与ID相关的，与ASD相关的和控制行为任务。同时，我们将获得初步单一核RNA-SEQ转录组学数据并进行初步分析，同时还检查了特定我们预测的染色质修饰将在基因突变小鼠模型中改变。这些公正，初步的实验将识别哺乳动物大脑中的新型下游靶标，阐明行为未来研究的结果指标，并产生新的假设，预计会带来未来的潜力治疗策略。
