60 minutes is considered “the most successful news magazine in TV history”. Don’t miss this CRISPR episode, featuring Feng Zhang, Eric Lander, Kang Zhang and Shoukhrat Mitalipov.
The exploit announced last week by Nature marks an advancement in CRISPR performance in human embryos big enough to say that yes, germ line editing will probably become a viable option sooner or later. It means that some genetic diseases (at least those caused by a single mutation) can be corrected not only in the treated individuals but also in their offspring. The idea of genetic diseases disappearing from the face of Earth is bound to remain a dream, as Eric Lander explained at the 2015 Washington Summit on Human Gene Editing. In short, with rare Mendelian diseases, the vast majority of situations can currently be addressed by in vitro fertilization and preimplantation genetic diagnosis, while complex diseases are, well, too complex to handle. Anyway, when you come to efficiency and accuracy, results achieved by Shoukhrat Mitalipov and colleagues are exciting: CRISPR science walks on robust and fast legs. As for the bioethics of the experiment, we should try not to get stuck with overused labels. Continue reading
