Newborns successfully delivered with genetically modified DNA from three parents, aiming to mitigate genetic disorders

In a significant breakthrough, eight healthy babies have been born in Britain using a revolutionary technique known as mitochondrial donation therapy, or the three-person DNA technique. This innovative method is designed to prevent children from inheriting mitochondrial disorders, rare genetic diseases that can cause severe disabilities and are often fatal.

The process begins with a fertilized egg from the parents, which contains both nuclear and mitochondrial DNA. The nuclear DNA, which determines traits like eye color and height, is extracted from this egg. This nuclear DNA is then transferred into a donor egg that has had its own nuclear DNA removed but retains its healthy mitochondrial DNA. The resulting embryo contains nuclear DNA from the parents (about 99.9%) and mitochondrial DNA from the donor (about 0.1%), significantly reducing the risk of inheriting mitochondrial disorders.

The recent successes in the UK have shown that this technique can lead to the birth of healthy children without the risk of passing on mitochondrial diseases. Each of the eight babies born using this method has been reported as healthy.

However, the use of this technique is not without controversy. In the UK, every couple seeking a baby born through donated mitochondria must be approved by the country's fertility regulator. Critics have raised concerns about the impact of novel techniques like this on future generations, but the Human Fertilisation and Embryology Authority in the UK has welcomed the findings, stating that the technique would only be available to those at very high risk of passing the disease to their children.

As of this month, 35 patients have been authorized to undergo the procedure in the UK. In contrast, the technique is banned in the United States due to ethical and regulatory concerns regarding the creation of "three-parent babies." No other countries have been reported to have legalized this specific technique openly, though research and discussions may be ongoing in various jurisdictions.

Liz Curtis, who founded the Lily Foundation after her daughter Lily died of a mitochondrial disease in 2006, expressed excitement for families with little hope, as the technique could provide an alternative. Andy Greenfield, a reproductive health expert at the University of Oxford, called the method "highly significant" and noted that it would only be used for a small number of women for whom other ways of avoiding passing on genetic diseases were not effective.

The research was conducted on 22 patients, resulting in eight babies that appear to be free of mitochondrial diseases. One woman is still pregnant. Follow-up of these children for many years would be important to ensure they remain healthy.

As the world continues to grapple with the ethical implications of such groundbreaking technologies, the success of the three-person DNA technique in the UK offers a glimmer of hope for families at risk of passing on rare genetic diseases.
