Gene silencing in fragile X syndrome  

Fragile X mental retardation syndrome (FXS) is the most common familial cause of intellectual disability and the most common known cause of autism. FXS arises when the number of CGG nucleotide repeats in the 5' UTR of the FMR1 gene exceeds 200. This results in FMR1 silencing and subsequent deficiency of FMRP protein. The FMRP deficiency in the brain results in aberrant dendritic spine morphology and a defective response to synaptic activation. This proposal aims to identify the mechanisms responsible for gene silencing of the FMR1 gene, with the ultimate goal of identifying steps that may be amenable to pharmacological intervention.

Strategic Plan Objective Green dot: Objective has greater than or equal to the recommended funding. 2SD. Launch three studies that target improved understanding of the underlying biological pathways of genetic conditions related to autism (e.g. Fragile X, Rett syndrome, tuberous sclerosis complex) and how these conditions inform risk assessment and individualized intervention by 2012.
