  • BioEdge: Ground shifts in UK debate over “three-parent embryos”
    and traits This approach was echoed in the media In a typical example New Scientist declared flatly last year So what about the three parent issue It is of questionable relevance Mitochondria contain genes but make no contribution to the traits that make us human personality intelligence appearance and so on A donor would have no more right to claim parenthood than someone who gives blood In any case the precedent set by ooplasmic transfer suggests that the issue has no practical significance Now however New Scientist has done a 180 degree turn on the issue because of some recent findings Now it appears that we may have seriously underestimated the influence that mitochondria have Recent research suggests that they play a key role in some of the most important features of human life This raises the ethically troubling prospect once widely dismissed including by this publication that children conceived in this way will inherit vital traits from three parents The magazine s editorial says that a serious debate about the ethics is needed before the mitochondrial transfer can be approved by Parliament And writing in BioNews Ted Morrow of the University of Sussex complained that politicians and the press fail to understand the complexity of genetics He pointed out an obvious inconsistency in the notion that mitochondrial DNA is unimportant It is therefore a contradiction to claim that mtDNA is not important for an individual s characteristics scientists call this the phenotype while at the same time acknowledging that changes in the mitochondrial genetic code are important for an individual s risk of disease again part of an individual s phenotype MORE ON THESE TOPICS media mitochondrial replacement three parent embryos This article is published by Michael Cook and BioEdge under a Creative Commons licence You may republish it

  • BioEdge: At long last, a follow-up study of “cytoplasmic transfer”
    Administration recommended a retrospective study to see how these children have fared the clinic is finally doing one Thirteen year old Alana Saarinen pictured above with her parents is one of those children A godsend to her mother who had a history of infertility she is healthy normal and cheerful But her parents were never contacted about her progress I wish someone would so they could see how healthy Alana is her mother told the London Telegraph The data will be of great relevance to the debate in the UK although it will probably not be available before Parliament votes Jacques Cohen the scientist who carried out the cytoplasmic transfer on the 17 IVF babies told the UK newspaper The Independent that no follow up on the children had ever been done despite the highly experimental and risky nature of the technique The current follow up study is ongoing and results will be made available in a medical journal Dr Cohen said although he is no longer working at St Barnabas Cytoplasmic transfer does differ from mitochondrial transfer In the former the mitochondria from both eggs are mixed together In the latter only the donor egg s mitochondria are used What little is known about cytoplasmic transfer is not promising A report from the Food and Drug Administration in 2002 pointed out that there had been two instances of Turner Syndrome one miscarried and one aborted amongst 30 pregnancies A paper by Cohen published in 2001 noted that an 18 month old child had been diagnosed with a pervasive developmental disorder MORE ON THESE TOPICS cytoplasmic transfer mitochondrial replacement This article is published by Michael Cook and BioEdge under a Creative Commons licence You may republish it or translate it free of charge with attribution for non commercial purposes following

  • BioEdge: British MP blasts “three-parent embryos”
    of globalisation we will be divorcing ourselves from the entire community of nations in terms of bioethics Do we really want to become a rogue state in terms of bioethics No one can deny the debilitations and hardships that these diseases cause No one is seeking to downplay that suffering but this is not about a cure This will neither heal nor cure a single human being suffering from these diseases What is worse when we talk about pronuclear transfer is that that effectively requires the creation of human beings for the sole purpose of harvesting their useful parts Is that really the sort of society in which we wish to live in which persons individuals are created their parts harvested and then destroyed merely to provide for other human beings There is no way that that can be considered ethical whether in terms of purely rational deductive natural law or by the system of Christian ethics on which we in this country have traditionally relied Naturally this controversial issue had strong defenders as well Chi Onwurah MP for Newcastle upon Tyne Central presented the views of scientists at the University of Newcastle who are passionate promoters of the technique In her view mitochondrial DNA represents only a tiny sliver of our genetic endowment so small that it is not worth worrying about She also used a slippery slope argument if gestational surrogacy which involves three parents is already legal how could the government possibly object to mitochondrial transfer The embryo would carry just 13 out of 23 000 or 0 056 of the genetic material from the mitochondrial donor As the right hon Member for Havant Mr Willetts said it is not the nuclear DNA so the child s appearance personality and other features are not affected In Britain

  • Lord Winston warns that IVF companies are exaggerating the effectiveness and safety of new techniques
    doing I don t think it is competent I think it is frightened of being sued Lord Winston is concerned about the way prenatal genetic screening is being marketed When you do this technique instead of improving the pregnancy rate you reduce it by as much as 50 per cent Winston said So prenatal genetic screening actually decreases the pregnancy rate but it is still being sold as a way of getting pregnant where there s been a failure In my view that s not honest Other relatively new developments in artificial reproduction are being used without due regard to their effectiveness or safety he said Many clinics for instance offer an eggs freezing service which is sold as useful for young women undergoing chemotherapy or other treatments that are likely to leave them sterile This is now becoming quite a big business It s really not likely to work Lord Winston said quoting figures showing that the overall success rate from egg freezing is less than 10 per cent Winston also believes that Mitochondrial Replacement Therapy needs to be studied further before it is carried out on human eggs The problem is that I don t believe there has been enough work done to make sure mitochondrial replacement is truly safe There probably needs to be a great deal more research in as many animal models as possible before it s done MORE ON THESE TOPICS egg freezing IVF mitochondrial replacement preimplantation genetic diagnosis This article is published by Xavier Symons and BioEdge under a Creative Commons licence You may republish it or translate it free of charge with attribution for non commercial purposes following these guidelines If you teach at a university we ask that your department make a donation Commercial media must contact us for permission and

  • BioEdge: HFEA finds mitochondrial transfer ‘not unsafe’
    of the review process the panel reached a view that the evidence it has seen does not suggest that these techniques are unsafe the report states Mitochondrial replacement therapy has the potential to prevent serious congenital diseases by removing mutant DNA from the mitochondria of embryos Some remain concerned about the safety of embryos who will first be experimented on In an article published in Public Discourse in March University of Utah stem cell scientist Maureen Condic warned of genetic complications in the therapy All three methods of mitochondrial transfer are highly likely to be unsafe for the resulting children even the ones that are not deliberately destroyed and are not damaged by the procedure itself MORE ON THESE TOPICS HFEA mitochondrial replacement three parent embryos UK This article is published by Xavier Symons and BioEdge under a Creative Commons licence You may republish it or translate it free of charge with attribution for non commercial purposes following these guidelines If you teach at a university we ask that your department make a donation Commercial media must contact us for permission and fees Some articles on this site are published under different terms Please enable JavaScript to view the comments
