  • Publication number: 20230144834
    Abstract: Modified G6PC (glucose-6-phosphatase, catalytic subunit) nucleic acids and glucose-6-phosphatase-? (G6Pase-?) enzymes with increased phosphohydrolase activity are described. Also described are vectors, such as adeno-associated virus (AAV) vectors, and recombinant AAV expressing modified G6Pase-?. The disclosed AAV vectors and rAAV can be used for gene therapy applications in the treatment of glycogen storage disease, particularly glycogen storage disease type Ia (GSD-Ia), and complications thereof.

  • Patent number: 11060110
    Abstract: The present disclosure describes improved adeno-associated virus (AAV) vectors for gene therapy applications in the treatment of glycogen storage disease, particularly glycogen storage disease type Ia (GSD-Ia). Described are recombinant nucleic acid molecules, vectors and recombinant AAV that include a G6PC promoter/enhancer, a synthetic intron, a G6PC coding sequence (such as a wild-type or codon-optimized G6PC coding sequence), and stuffer nucleic acid sequence situated between the G6PC promoter/enhancer and the intron, as well as between the intron and the G6PC coding sequence. The recombinant AAVs disclosed herein exhibit highly efficient liver transduction and are capable of correcting metabolic abnormalities in an animal model of GSD-Ia.

  • Publication number: 20190367944
    Abstract: Recombinant viruses, such as adeno-associated virus (rAAV) or lentivirus, for the treatment of glycogen storage disease type Ib (GSD-Ib) are described. The recombinant viruses use either the human glucose-6-phosphatase (G6PC) promoter/enhancer (GPE) or the minimal human G6PT promoter/enhancer (miGT) to drive expression of human glucose-6-phosphate transporter (G6PT). The disclosed vectors are capable of delivering the G6PT transgene to the liver and correcting metabolic abnormalities in a murine model of GSD-Ib. The recombinant virus-treated mice maintained glucose homeostasis, tolerated a long fast, and did not elicit anti-G6PT antibodies. Methods of treating a subject diagnosed with GSD-Ib using the recombinant viruses is further described.
