  • Patent number: 11369693
    Abstract: This disclosure provides methods and compositions for treating lysosomal storage diseases in a subject. In one aspect of the invention, a transgene product is delivered to a subject by administering a recombinant neurotrophic viral vector containing the transgene to the brain. The viral vector delivers the transgene to a region of the brain which is susceptible to infection by the virus and which expresses the encoded recombinant viral gene product. Also provided are compositions for delivery of a transgene product to a subject by administering a recombinant neurotrophic viral vector containing the transgene to the subject's brain. The transgene product may be any that is deficient in a lysosomal storage disease.
