The possibility of creating a baby from three parents has moved a step closer after fertility watchdog the Human Fertilisation and Embryology
Authority (HFEA) gave the idea the green light.
Scientists at Newcastle University are developing the technique to stop mitochondrial defects, which can kill, from being passed on from a mother to
her children. In advice to ministers, the HFEA set out safeguards for the techniques which could affect future generations and help eradicate serious
The HFEA did not explicitly ask for a change in the law but has left it up to ministers to decide whether they should ask Parliament to consent to
Although the science is complex, the idea behind the technique is simple. Mitochondria, the batteries inside every cell in a person's body, come from
the egg cell, so if a woman has defective mitochondria they will be passed on to her child.
The team at Newcastle can take the DNA out of the egg after fertilisation and put it into a healthy donor egg which has had everything removed apart
from healthy mitochondria. But mitochondria contain a tiny amount of DNA and the baby would inherit 0.2% of its DNA from the donor egg.
Interesting stuff! I didn't even know this was even close to being used, bit of a touchy subject though. I'm not quite sure where I stand with it.
