In a response to the public consultation, the charity Christian Medical Fellowship said the techniques were unethical. "We do not consider that the hunt for `therapies' that might prevent a small number of disabled children (with mitochondrial disease) being born justifies the destruction of hundreds if not thousands of embryonic human lives," the group said. It also said there were lingering concerns about the safety of the techniques.
British law forbids altering a human egg or an embryo before transferring it into a woman, so such treatments are currently only allowed for research. The government says it plans to publish draft guidelines later this year before introducing a final version to be debated in the U.K. Parliament next year.
Politicians would need to approve the use of the new techniques before patients could be treated.
