IRB scientists identify critical spots on the genome where gene editing could cause an unwanted response

CRISPR/Cas9 is a commonly used, very precise, gene editing technique whose development, by Jennifer A. Doudna and Emmanuelle Charpentier, was recognised with the 2020 Nobel Prize in Chemistry. Commonly known as "genetic scissors", CRISPR allows the introduction of the desired DNA sequence into (virtually) any spot of the genome, thus modifying or inactivating a gene. This technique is widely used in biomedical research and some CRISPR-based therapies are in clinical trials for the treatment of human blood disorders, some types of cancer and HIV, among other conditions.
