Optimized CRISPR guide RNA design for two high-fidelity Cas9 variants by deep learning

Source https://www.nature.com/articles/s41467-019-12281-8#Sec14 Highly specific Cas9 nucleases derived from SpCas9 are valuable tools for genome editing, but their wide applications are hampered by a lack of knowledge governing guide RNA (gRNA) activity. Here, we perform a genome-scale screen to measure gRNA activity for two highly specific SpCas9 variants (eSpCas9(1.1) and SpCas9-HF1) and wild-type SpCas9 (WT-SpCas9) in

Four U.S. CRISPR Trials Editing Human DNA to Research New Treatments

Breaking down how the gene editing technology is being used, for the first time in the United States, to treat patients with severe medical conditions Source Smithsonian.com Last fall, the birth of genetically edited twin girls in China—the world’s first “designer babies”—prompted an immediate outcry in the medical science community. The change to the twins’ genomes,
