First UK baby with DNA from three people born after new IVF procedure
Link -> First UK baby with DNA from three people born after new IVF procedure
The first UK baby created with DNA from three people has been born after doctors performed a groundbreaking IVF procedure that aims to prevent children from inheriting incurable diseases.
The technique, known as mitochondrial donation treatment (MDT), uses tissue from the eggs of healthy female donors to create IVF embryos that are free from harmful mutations their mothers carry and are likely to pass on to their children.
How mitochondrial donation treatment works
1
Mother’s
fertilised egg
2
Donor’s
fertilised egg
3
Donor egg
Unhealthy
mitochondria
Healthy
mitochondria
Nucleus
Parents’ nuclear material removed and kept
Donor nuclear material removed and destroyed
Parents’ nuclear material placed inside donor egg
The process has led to the phrase “three-parent babies”, though more than 99.8% of the DNA in the babies comes from the mother and father.
Research on MDT, which is also known as mitochondrial replacement therapy (MRT), was pioneered in the UK by doctors at the Newcastle Fertility Centre. The work aimed to help women with mutated mitochondria to have babies without the risk of passing on genetic disorders. People inherit all their mitochondria from their mother, so harmful mutations in the “batteries” can affect all of the children a woman has.
For affected women, natural conception is often a gamble. Some babies might be born healthy because they inherit only a tiny proportion of the mutated mitochondria.
But I wonder, How does child support work?
