WebJul 11, 2024 · Adenine base editors (ABEs) are novel genome-editing tools, and their activity has been greatly enhanced by eight additional mutations, thus named ABE8e. However, elevated catalytic activity was concomitant with frequent generation of bystander mutations. This bystander effect precludes its safe applications required in human gene therapy. Webbase can be removed by uracil–DNA glycosylase, followed by filling in with a thymine base to match the complementary adenine base now on the opposite strand, rendering the base editing permanent. As a proof of principle of a potentially safer alternative to NHEJ-mediated disruption of the PCSK9 gene in vivo, we
