Abstract: Provided herein is a gene therapy for PKP2 (Plakophilin-2), e.g. using an adeno-associated virus (AAV) vector. The promoter of the vector may be a MHCK7 promoter or a cardiac troponin T (HTNNT2) promoter. The capsid may be an AAV9 or AAVrh74 capsid or a functional variant thereof. Other promoters or capsids may be used. Further provided are methods of treatment, such as by intravenous, intracoronary, intracarotid or intracardiac administration of the rAAV vector, and other compositions and methods.

Abstract: Provided herein is a gene therapy for GLUT1 Deficiency Syndrome and related disorders using a recombinant adeno-associated virus (rAAV) virion as a vector to express an GLUT1 protein or functional variant thereof. The rAAV virion may use an endothelial-specific promoter, e.g., a FLT-1 or Tie-1 promoter. The capsid may be an AAV6, AAV8, AAV9, AAVrh.74, or AAVrh.10 capsid or a functional variant thereof. Other promoters or capsids may be used. Further provided are methods of treatment, such as by intracerebrally and/or intravenously of the rAAV virion, and other compositions and methods.

Abstract: Provided herein is a gene therapy for CSRP3 (Cysteine and Glycine Rich Protein 3)-related gene deficits associated with cardiomyopathy, e.g. using an adeno-associated virus (AAV) vector. The promoter of the vector may be a MHCK7 promoter or a cardiac troponin T (HTNNT2) promoter. The capsid may be an AAV9 or AAVrh74 capsid or a functional variant thereof. Other promoters or capsids may be used. Further provided are methods of treatment, such as by intravenous, intracoronary, intracarotid or intracardiac administration of the rAAV vector, and other compositions and methods.

Abstract: Parkin protein variants having activating mutations and/or fused to a mitochondrial targeting sequence are provided. The engineered Parkin may be a fusion protein including a mitochondrial targeting sequence (MTS); a transmembrane domain; and a Parkin protein or functional variant or fragment thereof, such as a Parkin having an N-terminal deletion. The MTS may be the MTS of PINK1 or a functional variant thereof. Alternatively or in addition, the engineered Parkin may have one or more activating mutations, such as single amino-acid substitutions. The engineered Parkin may be delivered in a vector, such as an adeno-associated virus (AAV) vector, and may be used to treat a disease or disorder, such as Parkinson’s disease or any of various neurodegenerative diseases.
