This image from video provided by the Newcastle Fertility Centre shows a nuclear genome from an egg carrying a mitochondrial DNA mutation being inserted into an egg donated by an unaffected woman ...

Mitochondrial DNA represents about 1 percent of total cellular DNA (about 1000 to 10,000 copies per cell). Mitochondria are the chief energy-producing organelles inside our bodies' cells.

A pioneering IVF technique combining DNA from three people to protect a baby from a rare genetic disease has been used in Britain, leading to a healthy cohort of eight babies with no sign of ...

The technique, developed by the Newcastle team, involves creating an embryo using DNA from three people: nuclear DNA from the intended mother and father, and healthy mitochondrial DNA from a donor ...

Researchers report that eight healthy babies were born with the help of an experimental technique that uses DNA from three people.

The presence of mitochondrial DNA mutations in babies born after pronuclear transfer treatment results from carryover of maternal mitochondria surrounding the nuclear DNA at the time of ...

The birth of eight babies with a greatly reduced risk of developing mitochondrial DNA disease provides hope for those waiting to access mitochondrial donation.

An experimental technique that patches defective DNA with donated genetic material helped families at risk of passing rare illnesses to their children.
