Human Fertilisation and Embryology (Mitochondrial Donation) Regulations 2015

Debate between Lord Ribeiro and Baroness Warwick of Undercliffe

Tuesday 24th February 2015 Lords Chamber

[Lord Ribeiro]

It was made very clear by the noble Lord, Lord Patel, and others that the need for the two techniques is to allow the HFEA to make a decision on which is the preferable technique. We have a situation at the moment where many of the embryos that are produced are discarded after the 14 days or so that are allowed. I will not go into the question of adoption. It is a matter of choice. If the family would prefer to have a child without this affliction, that is their choice, and they may not choose to go down the adoption route.

Returning to the subject of safety, as has been stated, no procedure can guarantee 100% safety. Even the natural birth that we all go through will produce children with defective genes and abnormalities; even nature cannot get it 100% right. To expect a situation where we have to demonstrate to all and sundry that this procedure is 100% safe is impossible.

Finally, it is important to recognise that passing this regulation is not opening Pandora’s box. We are not going down the route of eugenics and we will not create monsters. We must trust the scientists. We must recognise that we have regulation in this country—one of the most regulated countries in the world in the health field—and I believe that we must leave it to them to make the case. As was said by my noble and learned friend Lord Mackay of Clashfern, the decision was already made in 1990, when he was responsible for taking the Bill through Parliament. In 2008, it was modified with the full understanding that this type of technique might well be brought into use.

The day has come, the time has come and, frankly, we must just get on with it.

[Baroness Warwick of Undercliffe (Lab)]

My Lords, I come to this debate without any expert legal or medical experience or perspective. As a former chair of the Human Tissue Authority, I worked closely with the Human Fertilisation and Embryology Authority, the well established regulator in this area. I came to know the way in which it regulated and certainly had confidence in it, as indeed Parliament has. As a former chief executive of Universities UK, I am also familiar with the research trials that are rigorously and vigorously undertaken in health research before any change or new technique is introduced into clinical practice. I have come to know the bodies which speak for science and for medical research, such as the MRC and the Royal Society, and the Association of Medical Research Charities, of which my noble friend Lord Turnberg has been a scientific adviser, as well as the Nuffield Council and the Wellcome Trust. I realise how fortunate we are in this country to have pre-eminent organisations, respected around the world, the main aim of which is to ensure that research is rigorous, honest, thorough and ethical. I say all this because I take great comfort in the fact that, where there are complex areas of science or new techniques, particularly where they might be controversial—as with fertility and genetics—we have the knowledgeable, forensic and wise guidance of these bodies to help us in Parliament to arrive at secure solutions.

Mitochondrial DNA disease is severe. In most cases, we are told, it causes early infant death, and the few children who survive suffer multiple health problems. Mitochondrial donation, a new reproductive technology developed by our world-leading scientists in Newcastle, is important because it enables families affected to have a healthy child. Our decision today will be immensely important to those families.

A key question has been raised about the safety of the procedure. As others have said, while no medical procedure can be guaranteed to be 100% safe, a huge amount of testing has been done to establish the relative safety of this particular procedure.

I have no professional expertise in this or in any other area of disease. So, like most other women and men in the street, I rely on the rigour and competence of our regulators, ethicists and clinical testing systems to provide the best possible guidance on new techniques and procedures, to enable me to make up my mind—even if some of the evidence is contradictory. All the bodies that I referred to earlier, and others which represent the families of those tragically affected by the disease, favour this regulation to permit mitochondrial donation. They have provided excellent briefings, and there was a hugely helpful seminar yesterday where experts on different aspects of this issue addressed a range of concerns. They have pointed to seven years of intensive scrutiny, three separate reviews of the scientific evidence on the technique’s safety, independent ethical reviews and an extensive public consultation. Currently, the law allows for these techniques to be used only in research. It is up to us in Parliament to decide whether these techniques are ethical and whether they may, with safeguards, be used in patients.

The Nuffield Council on Bioethics found that, given the benefits to individuals if shown to be sufficiently safe, the techniques are ethical for families to use. The public, during consultation, concurred. The Wellcome Trust has helpfully set out the scientific evidence and detailed reasons why the procedure cannot be seen as genetic modification. What is very clear is that scientists throughout the lengthy period of research have been open and transparent. Nothing has been hidden, including their disagreements. There has been no conspiracy, as some of the critics seem to have suggested.

I found that I had a lot of sympathy with my noble friend Lord Turnberg and the noble Viscount, Lord Ridley. All the evidence I have seen and the arguments I have heard reassure me that this is not a slippery slope or an open door, or any other cliché. Nuclear DNA is not altered, so donation will not affect the child’s appearance or personality, or its uniqueness. It will simply allow parents to choose to have children who are genetically related to them but who are free from potentially devastating disease. I trust that the House will support these regulations.
