UK’s ‘Three-Person Baby’ Breakthrough: Fewer than Five Born So Far
New Hope for Fatal Mitochondrial Diseases
A revolutionary fertility technique aims to stop deadly mitochondrial diseases that can kill newborns within days. Fewer than five babies have been born using this method, but details remain tightly under wraps.
Mitochondrial diseases wreck the brain, muscles, heart, and eyesight – and they’re only passed down by mothers via faulty mitochondria.
How Mitochondrial Donation Works
Scientists have created a special IVF method called mitochondrial donation treatment. It uses mitochondria from a healthy donor egg alongside the parents’ DNA. This tiny bit of donor DNA powers healthy mitochondria without affecting other traits, so the donor isn’t a “third parent.”
UK Leads but Keeps Quiet on Numbers
Developed in newcastle/" title="Newcastle" data-wpil-keyword-link="linked">Newcastle, the UK legalised this method back in 2015 but didn’t rush to use it. The first known baby came from a Jordanian woman treated in the US in 2016. The Human Fertilisation and Embryology Authority (HFEA) has revealed fewer than five children have been born via this technique in the UK as of April 2023. Exact figures are secret to protect families.
“News that a small number of babies with donated mitochondria have now been born in the UK is the next step, in what will probably remain a slow and cautious process,” said Sarah Norcross, director of the Progress Educational Trust.
Challenges and Cautions Ahead
Scientists remain cautious. The Newcastle teams haven’t updated the public, and experts question whether the babies will stay clear of mitochondrial disease for life.
Professor Robin Lovell-Badge warned of possible “reversion,” where faulty mitochondria could regrow, causing the disease’s return. Originally, up to 150 babies per year in the UK were expected to be born this way.
This “three-person baby” method is a game-changer for families facing mitochondrial illnesses. As scientists refine the procedure, it could offer new hope – letting more families welcome healthy babies free from these devastating conditions.
