Human Fertilisation and Embryology (Mitochondrial Donation) Regulations 2015 — House of Lords, 2015-02-24
Topic: Health
Frederick Richard Penn Curzon (Conservative, Centre-right): My Lords, the purpose of the regulations is to enable women to have their own genetic children, free of terrible disease caused by disorders in their mitochondrial DNA. The regulations do so by allowing healthy mitochondria from a donor to replace the unhealthy mitochondria in a woman’s egg or embryo Mitochondria are present in almost every cell in the body and produce the energy that we need to function. This is why they are often referred to as the "powerhouse" of the cell. Unhealthy mitochondria can cause severe medical disorders known as mitochondrial disease, for which there is no cure. There are 37 genes in the mitochondrial DNA, compared with more than 20,000 in the nuclear DNA. This represents less than 0.1% of the total genetic make-up. The techniques provided for by these regulations offer the only hope for some women who carry the disease to have healthy, genetically related children who will not suffer from the devastating and often fatal consequences of serious mitochondrial disease Provision to make these regulations was introduced by Parliament into the Human Fertilisation and Embryology Act 2008. It followed an amendment that recognised the progress being made in research. In 2010, researchers at Newcastle asked the Department of Health to take forward steps to develop regulations. Over the last five years, there has been extensive engagement and consultation with the public on this issue, including, first, an ethical assessment by the Nuffield Council on Bioethics in 2012; secondly, a highly commended, respected and wide-ranging public dialogue and consultation exercise carried out by the HFEA in 2012-13; and, thirdly, a public consultation on draft regulations carried out by the Department of Health in 2014. There have been three separate reports into the safety and efficacy of these mitochondrial donation techniques by an expert panel convened by the HFEA, published in 2011, 2013 and 2014. The expert panel members were selected for their broad-ranging scientific and clinical expertise, and for having no direct or commercial interest in the outcome of the review This process was commended in a recent letter to the Guardian from eminent scientists and Nobel Prize winners from the UK and across the world. The letter included this sentence: "the UK has run an exemplary and internationally admired process for considering benefits, risks, ethical issues and public consent, which must properly precede a change in the law". Given the extensive scrutiny given to this issue during the life of this Parliament, I believe it is appropriate to allow this Parliament to decide whether to take the next step for mitochondrial donation, which can make meaningful progress to actually help families only with the passing of these regulations. The two proposed techniques that would be allowed under these regulations are maternal spindle transfer and pronuclear transfer. These replace the mitochondrial DNA, which contains a small number of unhealthy genes, with healthy mitochondrial DNA. Mitochondrial DNA is just 0.054% of our overall DNA. One important point to emphasise here is that none of the nuclear DNA, which determines our personal characteristics and traits, is altered by mitochondrial donation I know that many noble Lords will have their own tributes to pay, but I would like to make my own acknowledgment of the ground-breaking work that the scientists at Newcastle University have led, which is world-leading in the development of these new techniques. It is also very important to praise the Lily Foundation, a charity founded by families who have lost their children to serious mitochondrial disease, which has reminded us about the human story that inspired this scientific advance I turn now to the detail of the regulations made under powers in the 1990 Act which, as I said, were added in 2008, with Parliament’s express agreement, in anticipation of the advancement of science to this point. These powers would permit mitochondrial donation in order to prevent the transmission of serious mitochondrial disease.
