Using a technique known as mitochondrial replacement, doctors were able to extract the nucleus from one of the mother’s eggs, inserting it into a donor egg with a nucleus removed.
The egg was then fertilised with the father’s sperm, meaning the baby has DNA from two mothers and one father – also preventing the disease from being passed on.
As the procedure is not legal in the US, it was carried out in Mexico.
According to the outlet, the findings will be outlined next months at the American Society for Reproductive Medicine’s Scientific Congress.
Last year the UK became the first country to approve a law to allow babies to be created from the DNA of three people using the technique.
