A new development has emerged as Britain legalise the creation
of a three-parent baby using healthy DNA from a donor to fix debilitating
genetic problems.
The fertility clinic regulator Human Fertilization and
Embryology Authority (HFEA) UK has approved the technique, developed by British
scientists, to replace an egg’s defective mitochondrial DNA with healthy
mitochondrial DNA from another female donor to prevent the child from suffering
from genetic flaws with a “caution use”.
HFEA Chairwoman Sally Cheshire said in an announcement
Thursday that endorsement of the strategy is "extraordinary" for
families. Guardians who confront a high danger of having a kid with an
existence debilitating mitochondrial illness "may soon have the possibility
of a sound, hereditarily related kid," she said.
This practise may cause court challenges down the line over
custody or inheritance. Because the baby would have two biological mothers and
a father.
The technique was approved by in specific situation by HFEA only
after all other options have been exhausted, such as screening for healthy
embryos.
Application can begin immediately for Fertility clinics that
wants to obtain a license to carry out the procedure and could being using it
in early 2017, with the first three-parent babies likely to be born late in the
year as reported.
It is not everybody that is excited about the development.
Critics are concerned about the unknown consequences of major genetic changes
being passed on for generations.
Another fear they have is that Britain could open the
floodgates to “designer babies,” created with particular characteristics and
washed of genetic flaws or less desirable traits.
But other people support the technique, saying that it is a
way to help parents having genetic issues to have a healthy family.
