The relatively newborn practice of birthing babies from the DNA of three persons was just sanctioned in the United Kingdom beckoning potential controversies and progress.
The very phrase three parent babies may seem bizarre, but science has backed up the new advancement. Every day, an increasing number of studies and trials are carried out and a large number of them targeted on gene practices.
One of such is the use of mitochondrial DNA, which carries about 37 genes in humans and one of the first significant human genome to be sequenced.
In most of the cases, mitochondrial DNA is carried through to the baby solely from the mother, but it may often contain genetic problems.
That is exactly the point, where the three-parent baby idea comes in, to prevent the possible transmission of bad genes, scientist can now take control of the situation and now introduce healthy genes.
The technique is used for in-vitro fertilization with third party healthy genes becoming healthy to be donated. So such mitochondrial DNA samples are used to take the place of inherently faulty mother DNA.
Previous week, the UK permitted the use of such a method to be carried out becoming the first country to legalize the new technique. Unbeknownst to the medical and ethical concerns the idea has always had and probably still persistently will.
The medical concerns are targeting the safety of such a practice. HFEA or the Human Fertilization and Embryology Authority is the United Kingdom fertility regulator.
They have approved the technique and reported to have carried out investigations. The legalization came two weeks after such an investigation.
Last month, HFEA convened an independent expert scientific panel. They published their fourth review on the efficiency and safety of mitochondrial donations. According to them, the three parents baby is safe to use. However, they did recommend a series of regulations.
