Roles Of Autism Gene Arid1b In Murine Brain Development And Behavior, Amanda L. Smith

Theses & Dissertations

Autism spectrum disorder (ASD) and intellectual disability (ID) are highly prevalent neurodevelopmental disorders characterized by social and communication deficits, stereotyped behaviors, cognitive dysfunction, and deficits in adaptive behaviors. The pathogenesis underlying these disorders remains unknown, and thus no pharmacologic or genetic therapies are currently available. Recent progress in the field has shown that haploinsufficiency of the AT-rich interactive domain-containing 1B (ARID1B) gene is a genetic cause of ASD and ID. Our lab recently developed an Arid1b knockout mouse model to better study its role in the pathogenesis of these disorders. One theory regarding the cause of neurodevelopmental disorders …

Arid1b And Macf1 In Murine Brain Development And Behavior, Jeffrey Jay Moffat

Theses & Dissertations

Intellectual disability (ID) and autism spectrum disorder (ASD) affect between one and three percent of the global population. These disorders represent a significant emotional and financial burden for affected individuals and their families. Treatment for these conditions remains limited because many of the key molecular factors and associated pathogenic mechanisms are still poorly understood.

In this report we examine two genes related to ASD and ID, AT-rich interactive domain-containing protein 1B (ARID1B) and Microtubule-actin crosslinking factor 1 (MACF1). ARID1B is a subunit of the mammalian BRG1/BRM associated factor (BAF) chromatin-remodeling complex, which broadly regulates gene expression. ARID1B also …
