Summary:
- This article discusses a new in vitro fertilization (IVF) technique that uses DNA from three people to create healthy babies and prevent the transmission of inherited diseases.
- The technique, called mitochondrial replacement therapy, involves replacing the mother's faulty mitochondrial DNA with healthy mitochondrial DNA from a donor, while still using the mother's and father's nuclear DNA to create the embryo.
- This approach has been successful in helping families with mitochondrial disorders, which can cause a range of serious health problems, to have healthy children without passing on the genetic defects.
