Abstract:
Adeno-associated viruses (AAVs) are preferred gene therapy vectors because of their versatility, durability and safety profile. Here, we demonstrate extensive chimerism, manifesting as pervasive barcode swapping, among complex recombinant AAV (rAAV) libraries that are packaged as a pool. The observed chimerism is length and homology dependent but capsid independent, in some cases affecting the majority of packaged rAAV genomes. These results have implications for the design and deployment of functional rAAV libraries.

Gene Duplication and Divergence
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are characterized.
