Ahsan Saeed: DNA From Three Parents Just Stopped a Life-Threatening Disorder Before Birth!
Ahsan Saeed, Doctor of Medicine at Faculty of Public Health, shared a post on LinkedIn:
“DNA from three parents just stopped a life-threatening disorder before birth!
A new era for genetics has begun.
Doctors in the UK have achieved something once thought impossible – babies born with DNA from three biological parents to prevent deadly genetic disease.
So far, eight healthy babies have been delivered using this groundbreaking method, designed to stop the transmission of mitochondrial disorders that can cause organ failure, seizures, and even death soon after birth. For families carrying these inherited conditions, the breakthrough offers not just treatment – but prevention.
Here’s how it works: doctors fertilize two eggs — one from the mother and one from a healthy donor — with the father’s sperm. Then they transfer the parents’ DNA into the donor egg, which contains healthy mitochondria. The result? A child genetically linked to their mother and father, but carrying a trace of donor DNA (just 0.1%) to ensure a healthy start.
Every baby born so far is developing normally. As one mother said, ‘After years of uncertainty, this treatment gave us hope – and then it gave us our baby.’
