METHODS AND COMPOSITIONS FOR TREATING GLYCOGEN STORAGE DISEASES

Abstract:

This invention provides a variety of novel adeno-associated vims (AAV) vectors for gene therapy applications in the treatment of glycogen storage disease type 1a (GSD-Ia). Disclosed herein are a number of recombinant nucleic acid molecules, vectors and recombinant AAV that incorporate a modified G6PC promoter/enhancer sequence. Utilization of the modified G6PC promoter/enhancer sequence results in enhanced AAV yield and quality when expressed from various host cell platforms. Also provided herein are compositions comprising the novel AAV of the invention and methods of treating GSD-Ia using the same.
