We do know that a naturally born baby contains genetic material (deoxyribonucleic acid, or DNA) coming from two parents, but three DNA techniques through in-vitro fertilisation (IVF) have allowed the birth of babies with genetic material procured from three people. The world’s first baby was born using this technique in the U.S. in 2016. Recently, the UK’s fertility regulator, HFEA (Human Fertilisation and Embryology Authority), confirmed the births of the UK’s first babies using the same technique. This technique involves 99.8% DNA from the two parents and 0.1% from the third person, which is a donor woman.
This method has been developed to protect children from rare inherited genetic disorders such as mitochondrial disorders and diseases. Mitochondria are the source of energy in living cells. Mitochondrial disorders are terminal and fatal; about 1 in 200 children in Britain are born with such disorders.
The donor’s DNA is being used to make mitochondria but is not involved in passing any trait such as appearance or like a third-parent copy. This procedure is also known as pronuclear transfer.
Is this technique completely safe? People have their speculations, and research is going on. Pros (prevention from diseases) and cons (reversal and long-term effect) are associated, while twisting of the genetic code could have a ripple effect and eventually lead to endearment for designer babies. The findings of the research and experiments are under scientific peer review.
