Britain
has become the first country to legalize the creation of in vitro fertilization
(IVF) babies using three parents, which doctors say could prevent inherited
genetic diseases.
The
House of Lords voted on Tuesday for a change in the law to allow the treatment.
The peers rejected an attempt to block the plan by 280 votes to 48.
The
techniques are still in their research stages in laboratories in Britain and the
United States. However, the first baby conceived using DNA from three different
people may be born as early as 2016.
The story continues:
A
spokesperson for the Department of Health said: “Parliament's
decision will bring hope to hundreds of families affected by mitochondrial
disease.
“We are proud to be the first
country to allow these revolutionary techniques.
“For the first time ever, women
who carry severe mitochondrial disease will have the opportunity to have
healthy babies without the fear of passing on devastating genetic disorders.”
A
three-parent child would have “nuclear” DNA
determining individual traits such as facial features and personality from its
two parents, plus a tiny amount of healthy mitochondrial DNA (mDNA) from a
female donor.
The
mitochondria, extracted from a donor, would be implanted in an egg to replace
any damaged or unhealthy mitochondria, which can cause inherited conditions
such as heart problems, liver failure, brain disorders, blindness and muscular
dystrophy.
However,
critics warn the move will lead to the creation of “designer
babies.”
Church
leaders and pro-life groups warn the risks of the procedure are not yet fully
known, and say the change was being pushed through too hastily. They also warn
the legislation could trigger a “slippery slope”
towards designer babies and eugenics.
The
Center for Genetics and Society (CGS) called this decision “a
historic mistake” and warned the technique “will
turn children into biological experiments.”
“The techniques in question are
relatively crude and will not in and of themselves create so-called ‘designer
babies’, as that term is typically understood,” the group said.
“However they will result in
children with DNA from three different people in every cell of their bodies,
which will impact a large range of traits in unknowable ways, and introduce
genetic changes that will be passed down to future generations through the
female line.”
The
chief medical officer for England, Dame Sally Davies, denied the legislation
would give way to the creation of designer babies.
“This is about changing the
battery packs, it's not about touching the chromosomes that make us what we
are,” she
said. “The nucleus is
sacrosanct and it is illegal to touch it.”
Prime Minister David
Cameron, Labour leader Ed Miliband and Deputy Prime Minister Nick Clegg all
used their free votes to support the decision.
