The clever new approach focuses on the first step, which could help patients suffering from genetic diseases caused by two mutations located within a single gene (compound mutation). This concept circumvents the need to utilize the second step of the gene editing technology in these compound mutations because the inventors capitalized on the allele exchange process that occurs in a normal biological setting.
