United Kingdom allows the fertilization of babies with the DNA of three parents


The UK fertilizer regulator now authorizes a procedure that allows three-parent babies to be born as a way to prevent the passage of a genetic disease from mother to child.

The UK regulator has allowed clinics to move forward with these procedures that allow the birth of babies with DNA from three different people for the simple reason of this procedure to prevent genetically-transmitted diseases, according to The Guardian, The Human Fertilization and Embryology Authority decided to grant the licenses to the clinics after having met to analyze the scientific studies carried out regarding the safety of this procedure.

Doctors in Newcastle will now be able to perform an experimental technique called Mitochondrial Replacement Therapy, which aims to prevent women from passing on severe genetic disorders to their children.

Women with this problem in the mitochondria (cellular structures that produce energy for individual cells) pass these deficiencies on to their children, so this new technique allows avoiding it. This disease affects one in every 10,000 newborns, who eventually die young, after brain, heart, muscle and other functions of the human body, begin to fail due to lack of energy in the cells.

In this process, the mitochondria with genetic malformations of the mother are replaced by others with DNA from a healthy donor, which then join the DNA of the parents. That is, the baby is born with genetic material from three different parents.

In September, New Scientist magazine reported that five months earlier had been born the first baby with the genetic code of three different people. The revolutionary technique allowed Abrahim Assan to be born in Mexico, the place chosen for the procedures, since there was a legal void in the country.
