The UK has seen the first baby to be born with three people’s DNA, with the use of a pioneering technique, that was only made legal in 2015 with help from mitochondrial disease charity, the Lily Foundation.
The IVF technique means that whilst most of the baby’s DNA will be from two parents, around 0.01% of the baby’s DNA will be from a third donor.
The DNA replacement therapy can prevent devastating mitochondrial diseases, which are incurable and often fatal soon after birth.
Liz Curtis, CEO and founder of the Lily Foundation called the birth of the baby a ‘huge excitement’ for the mitochondrial disease community: “The future is looking really bright for the mitochondrial disease community. It’s something we worked so hard toward. It’s a huge excitement, but it’s important to acknowledge there is still a long way to go.”

Mitochondrial diseases are a result of a gene mutation, and the mitochondrial donation therapy (MDT) replaces the faulty gene through the IVF process.

Peter Thompson, chief executive at the HFEA, described to the Guardian: “MDT offers families with severe inherited mitochondrial illness the possibility of a healthy child. The UK was the first country in the world to allow MDT within a regulatory environment … These are still early days for MDT and the HFEA continues to review clinical and scientific developments.”
The Lily foundation campaigned for MDT to be made legal in the UK in 2015, after those in opposition to the technique called it ‘unethical’.
Liz said: “We projected the voice of the patient. The 2015 debate was focusing on the science and many in the opposition held the view that it was just about pushing the boundaries of science. But we provided the human aspect to the science.”
Liz started the Lily foundation in 2007 after the loss of her eight-month-old daughter, Lily, after realising there were no mitochondrial disease charities in the UK that they could donate to.
