In some aspects, cardiac-specific expression cassettes are provided herein. In some aspects, provided herein is an expression cassette comprising a polynucleotide sequence encoding a gene product for therapy of a heart disease, wherein the polynucleotide sequence is operably linked to promoter (e.g., a cardiac-specific promoter), and optionally an enhancer (e.g., a cardiac-specific enhancer). In some aspects, the disclosure provides recombinant adeno-associated virus (rAAV) virions, comprising a capsid protein and a viral genome comprising an expression cassette comprising a polynucleotide sequence encoding a therapeutic gene product, e.g., dwarf open reading frame (DWORF) polypeptide, operably linked to a promoter, the expression cassette flanked by inverted terminal repeats. The disclosure further provides pharmaceutical compositions and methods of treating or preventing heart disease.

Optimized expression cassettes for gene therapy

The present disclosure provides recombinant adeno-associated virus (rAAV) virions with an engineered capsid protein identified using a high-throughput sequencing screen or rational design. In particular, the disclosure provides AAV5 virions and capsid proteins with increased transduction efficiency in cardiac cells, increased cell-type selectivity, and/or other desirable properties.
