Three-person IVF method employs genetic material from three individuals to prevent offspring from inheriting genetic illnesses, yet this practice is prohibited in the United States.

Genetic diseases averted for eight UK children through innovative three-person IVF method, according to Newcastle University researchers. Banned in the U.S., this procedure involves the transfer of maternal egg components, specifically the nucleus, along with the father's sperm nucleus.

Genetic disorder-evading IVF procedure employs DNA from three individuals, yet it's prohibited in the United States

Three-person IVF method employs genetic material from three individuals to prevent offspring from inheriting genetic illnesses, yet this practice is prohibited in the United States.

In a remarkable scientific advancement, eight children have been born in the UK, all free from genetic diseases, thanks to a novel three-person IVF technique. This breakthrough, which has been meticulously developed over several decades, is set to open up new avenues of investigation in the medical community.

The procedure, known as mitochondrial replacement therapy, prevents the transfer of mutated genes from inside the mother's mitochondria. In this process, a small amount of healthy mitochondrial DNA from an egg donor is combined with the mother's egg and the father's sperm, reducing the risk of passing on genetic diseases linked to mitochondrial DNA defects.

This technique has been controversial, particularly in the United States, where it is not yet approved. The Food and Drug Administration (FDA) has not yet given its nod to this method, and the debate about its potential approval continues. In contrast, the UK approved mitochondrial replacement therapy in 2015, making it the first country to do so.

The UK's regulatory framework permits the use of donor mitochondria, constituting a very small percentage (about 0.1%) of the child's DNA. This has enabled clinical trials, resulting in the successful birth of several healthy babies using this method.

The process involves several steps. The donor egg begins to divide and develop with its healthy mitochondria, while the mother's egg and the father's sperm provide the nuclear DNA. In cases where all the eggs' mitochondrial DNA carries mutations, the new technique involves fertilizing the mother's egg with the father's sperm, followed by removing the fertilized egg's pronuclei to make room for the mother's egg and father's sperm nuclei.

The donated fertilized egg's pronuclei are then removed, and pieces from inside the mother's fertilized egg and the father's sperm are transferred into the healthy egg provided by an anonymous donor. This results in the replacement of the faulty mitochondrial DNA with healthy mitochondrial DNA from the donor.

Blood levels of mtDNA mutations were significantly lower in all newborns compared to their mothers' levels, indicating the success of the procedure. Mutations in mitochondrial DNA can affect multiple organs, particularly those that require high energy like the brain, liver, heart, muscles, and kidneys.

All eight children have made normal developmental progress, and one is currently pregnant. There have been no miscarriages reported. The researchers' "treasure trove of data" from this study is likely to be the starting point of new avenues of investigation.

Despite the promising results, ethical considerations surrounding three-person IVF remain a topic of discussion. The potential for genetic modification and the creation of "designer babies" are concerns that need to be addressed as this technology continues to evolve.
