OHSU The media well and truly pricked up its collective ears when US geneticist Shoukhrat Mitalipov last month showed that he could use the CRISPR gene-editing system in a very early human embryo to correct a mutation that can cause heart defects. Such excitement is understandable. Even if his work wasn’t the first of its type, it was arguably the most sophisticated and had the most promising results, a proof in principle that opens the door to possibly modifying other genes. How about targeting a mutated APP gene, linked to risk of early-onset Alzheimer’s?
