One baby with DNA from three parents

Britain first to officially introduce procedures.

London: British scientists on Thursday approved the use of so-called “three-parent baby” fertility treatments, paving the way for the country to become the first in the world to officially introduce the procedures.

An independent panel of experts tasked with reviewing the safety of mitochondrial gene therapy said the practice should be “cautiously adopted” to prevent certain genetic diseases from being passed on to future generations.

British MPs voted in February to allow the creation of IVF babies with DNA from three people. However, the country’s fertility regulator, the Human Fertilisation and Embryology Authority said it wwill wait for today’s report before green-lighting use of the treatment in clinics.

The technique would allow women who carry disease-causing mutations in their mitochondrial genes to give birth to genetically-related children free of mitochondrial disease.

The treatment involves the embryo receiving the usual “nuclear” DNA from the mother and father, as well as a small amount of healthy mitochondrial DNA from a female donor.
