Baby With A DNA of Three Parents Is Born In Greece

On Tuesday, a 32-year-old Greek mother has given birth to a baby with DNA from three people in Greece. The baby boy, who weighs 2.9kg (6lb), and his mother, who is 32, are said to be in good health. Dr. Panagiotis Psathas, president of the Institute of Life in Athens, said, “We are very proud to announce an international innovation in assisted reproduction, and we are now in a position to make it possible for women with multiple IVF (In Vitro Fertilization) failures or rare mitochondrial genetic diseases to have a healthy child.” It is the first time an IVF technique involving DNA from three people has been used with the aim of addressing fertility problems.

The study took on 25 women under 40 years old who had already had at least two previous failed IVF attempts. The team had to conduct the trial in Greece because the procedure is not approved in Spain, according to the health news website Stat News, which reported the woman’s pregnancy in January this year.

About The Experimental IVF Treatment

The medical team in Barcelona used a technique called maternal spindle transfer (MST), in which maternal DNA is put into the egg of a donor woman, which is then fertilized using the father’s sperm. The technique hinges on cell structures called mitochondria, which turn food sources into useable energy.

Mitochondrial Donation – the experimental IVF treatment involves using an egg from the mother, sperm from the father, and another egg from a female donor. The vast majority of a person’s genes – about 99.8% – are found on the 23 pairs of chromosomes that sit inside the nucleus in each cell in the body, and in the IVF procedure, this DNA comes from the two parents. However, a tiny proportion of genetic material also resides in a cell’s mitochondria, small structures that act as the cell’s batteries and float around freely in the cell body. In mitochondrial donation, the mother’s mitochondria are removed from her egg and replaced by a donor’s.

The doctors claim that mitochondria also play a role in a successful pregnancy and suggest that the technique could be applied more broadly as a fertility treatment. The 32-year old woman in the latest case had previously undergone four unsuccessful rounds of IVF. Nuno Costa-Borges, the Spanish embryologist who collaborated with the Institute of Life clinic in Greece, where the treatment took place, said it could help “countless women” to become mothers and described the advance as a revolution infertility treatments.

The Controversy and Criticism

The treatment was originally developed as a treatment that could prevent women with debilitating or even fatal mitochondrial diseases from passing them on to their children. The treatment was made legal in the UK in 2015, but so far, no other country has introduced laws to permit the technique. There is only one known instance of the technique being applied clinically, in which a family from Jordan was treated by US doctors at a Mexican clinic, prompting controversy.

Although, the doctors from Greece and Spain, who are responsible for the treatment, claimed they were “making medical history” with a procedure that could help infertile couples around the world. Experts from the UK have criticized the decision to proceed with the treatment, which they said was not backed by evidence and involved unjustifiable risks. There have been claims by many that the technology is entirely untested.

Tim Child, an associate professor at the University of Oxford and the medical director of the Fertility Partnership, said: “The risks of the technique aren’t entirely known, though maybe considered acceptable if being used to treat mitochondrial disease, but not in this situation. “The patient may have conceived even if a further standard IVF cycle had been used. Without a proper well-designed study, with the use of controls, it is not possible to say whether this technique has benefitted the patient.”

A spokeswoman for the Human Fertilisation and Embryology Authority, the UK fertility regulator, said that in the UK, each application for treatment is considered on an individual basis and only for patients who have a very high risk of having a child with a life-threatening mitochondrial disease. “There is limited evidence on risks and success rates, and it should only be used cautiously in cases where alternative treatments would be of little or no benefit,” she added.

There are about 2,500 women in the UK with mitochondrial disease who could benefit from the procedure.

Dr. Nuno Costa-Borges said,

“Spindle transfer may represent a new era in the IVF field, as it could give these patients chances of having a child genetically related to them.”
