Fertility doctors say the world’s first baby has been born using DNA from three parents in a technique hailed as “revolutionary”.
The controversial “three-parent” technique allows people with rare genetic mutations to have healthy babies.
The baby called Abrahim, whose mother and father are Jordanian, was born in Mexico with the help of a New-York based team led by
Dr John Zhang.
The mother has genes for Leigh syndrome, a fatal disorder that affects the developing nervous system.
Her son was conceived from an egg containing nuclear DNA from his parents, and mitochondrial DNA from a “second” mother – an
unknown female donor.
The technique has been approved in the UK – but this time it was altered slightly because as Muslims the parents were against the destruction of embryos.
The aim was to replace defective mitochondrial DNA that may have condemned Abrahim to Leigh syndrome.
