Abstract
The present disclosure provides engineered capsid proteins and recombinant adeno-associated virus (rAAV) virions with an engineered capsid protein. In particular, the disclosure provides AAV9 virions with engineered AAV9 capsid, AAV5/9 chimeric capsid, or combinatory capsid that achieves increased transduction efficiency in heart, increased heart-to-liver ratio, and/or other desirable properties.

A recombinant adeno-associated virus (rAAV) capsid protein, wherein the capsid protein shares, or comprises a sequence sharing, at least 80% amino acid sequence identity to an AAV9 VP3 reference sequence according to SEQ ID NO:
- 487, and wherein the capsid protein comprises, relative to reference sequence SEQ ID NO:
- 1:
- an amino acid insertion at position 584, or between positions 583 and 584, comprising one or more of an asparagine (N), a threonine (T), a tyrosine (Y), phenylalanine (F), and an alanine (A);
- an amino acid insertion at position 585, or between positions 584 and 585, comprising one or more of a histidine (H) and a methionine (M);
- an amino acid insertion at position 586, or between positions 585 and 586, comprising one or more of a histidine (H), a tyrosine (Y), a valine (V), a threonine (T), an alanine (A), an isoleucine (I), a tryptophan (W), a methionine (M), and a leucine (L);
- an amino acid insertion at position 587, or between positions 586 and 587, comprising one or more of an isoleucine (I) and a proline (P);
- an amino acid insertion at position 588, or between positions 587 and 588, comprising one or more of an isoleucine (I), a threonine (T), and a proline (P);
- an amino acid insertion at position 589, or between positions 588 and 589, comprising one or more of a glycine (G) and a glutamine (Q);
- one or more amino acid substitutions selected from the group consisting of N452K, N452A, N452V, N452I, G453A, G453N, S454T, S454D, G455N, Q456L, Q456K, N457L, N457V, Q458I, and Q458H;
