Progress

EGG_2565177b Yesterday the UK government set out new draft regulations which will allow donor DNA from a ‘second mother’ to be implanted into a defective egg. Mitochondrial donation, known as the “three-parent” baby technique, was deemed not to be a genetic modification that would, as critics feared, lead to the “slippery slope” of designer babies. MPs discussed the issues of medical ethics and scientific terminology at length and reached a pleasing decision.
Mitochondria is a part of the cell cytoplasm outside the central nucleus where chromosomes are located. They convert glucose to something called ATP, which is the universal energy currency of each and every cell in the body. Around one in every 200 babies born in the UK has a severe mitochondrial disease. Although rare, the disorders can be passed to future generations through the maternal line. Examples of mitochondrial diseases include conditions that cause muscle wasting, nerve damage, loss of sight and heart failure.
This is a brilliant development for families affected by mitochondrial diseases. I am thrilled that those with genetic abnormalities will have the opportunity to have the healthy children they so desperately want.
