An international team of researchers has used CRISPR-Cas9 gene editing - a technique that allows scientists to make precise changes to genomes with relative ease - to correct a disease-causing mutation in dozens of viable human embryos. The study represents a significant improvement in efficiency and accuracy over previous efforts.

The researchers targeted a mutation in a gene called MYBPC3. Such mutations cause the heart muscle to thicken - a condition known as hypertrophic cardiomyopathy that is the leading cause of sudden death in young athletes. The mutation is dominant, meaning that a child need inherit only one copy of the mutated gene to experience its effects.
