A recombinant adeno-associated virus (rAAV) vector comprising an AAV capsid having a heterogeneous population of vp1 proteins, a heterogeneous population of vp2 protein and a heterogeneous population of vp3 proteins. The capsid contains modified amino acids as compared to the encoded VP1 amino acid sequence, the capsid containing highly deamidated asparagine residues at asparagine-glycine pair, and further comprising multiple other, less deamidated asparagine and optionally glutamine residues.

Adeno-associated virus (AAV) vectors, AAV vectors having reduced capsid deamidation and uses therefor

A recombinant adeno-associated virus (rAAV) vector comprising an AAVhu68 capsid produced in a production system comprising a nucleotide sequence of SEQ ID NO: 1, or a sequence at least 75% identical thereto which encodes SEQ ID NO:2. The AAVhu68 capsid comprises subpopulations of highly deamidated asparagine residues in asparagine-glycine pairs in the amino acid sequence of SEQ ID NO: 2. Also provided are compositions containing the rAAV and uses thereof. Additionally, rAAV having an engineered AAV capsid comprising at least one subpopulation of vp1 or vp2 proteins having a Val at amino acid position 157 with reference to the AAVhu68 vp1 numbering are provided.
