A new technique that combines the DNA of three people has been used to create healthy babies in the UK, according to the country’s fertility regulator. The method, called mitochondrial replacement therapy (MRT), aims to prevent severe genetic diseases that are caused by faulty mitochondria, the tiny structures that provide energy to cells.
Mitochondria have their own DNA, which is separate from the nuclear DNA that contains most of our genes. Some people inherit mutations in their mitochondrial DNA that can lead to serious conditions such as muscular dystrophy, epilepsy, heart problems and intellectual disabilities. These mutations are passed on from mother to child through the egg.
MRT involves transferring the nuclear DNA from an egg or embryo of a woman with faulty mitochondria into a donor egg or embryo that has healthy mitochondria but no nuclear DNA. The resulting egg or embryo is then fertilized with sperm and implanted into the mother’s womb. The baby inherits nuclear DNA from both parents and mitochondrial DNA from the donor. The donor’s contribution is less than 1% of the baby’s total DNA.
The UK was the first country in the world to legalize MRT in 2015, after years of scientific and ethical debate. The Human Fertilization and Embryology Authority (HFEA) regulates the use of MRT and grants approval to eligible patients who have no other options for having a healthy biological child. So far, 32 patients have been authorized to receive MRT.
The HFEA confirmed that fewer than five babies have been born using MRT in the UK, but did not provide any further details to protect the privacy of the families. The first baby born using MRT was reported in the US in 2016 by a team of doctors who performed the procedure in Mexico.
The scientists at Newcastle University who pioneered MRT in the UK are expected to publish their results soon. They have been cautious and have followed up on the health of the babies and their families. They have also ensured that only male embryos are transferred, as female embryos could pass on their mitochondrial DNA to their offspring.
MRT is a groundbreaking technique that offers hope to families affected by devastating mitochondrial diseases. However, it is still a new and experimental procedure that requires careful monitoring and regulation. More research is needed to understand its long-term effects and implications for future generations.
these people are messing with things the Lord never intended. This is as bad as Hitler trying to make a super race. Come on people wake up before it’s to late.
