Adeno-associated viral vector-mediated gene therapy for treating fragile x-associated disorders

Abstract

The present application provides adeno-associated viral vector-mediated gene therapy for treating Fragile X-associated disorders, including Fragile X Syndrome (FXS). In particular, there is provided a vector comprising an adeno-associated vims (AAV) genome or a derivative thereof and a nucleic acid sequence encoding a Fragile X Mental Retardation Protein (FMRP) isoform that lacks exon 12 and includes exon 14 of the full length FMRP gene, such as a human or a murine Group C FMRP isoform. Also provided are related pharmaceutical compositions comprising this vector, and methods and uses thereof for the treatment of Fragile X-associated disorders, including FXS.
