Biobank UK – A Good Research Priority?

The Government is backing a controversial new genetic research project called ‘Biobank UK’. The project aims to identify the links between genetic and environmental factors in common diseases by studying DNA samples taken from 500,000 45 to 69 year olds. Each person’s genetic The Science and information will be linked with their lifestyle and medical Technology data.

The project should be shelved until the controversies surrounding it have been fully debated and resolved and alternative approaches have been properly assessed.

Biobank UK – good for public health? The aim of Biobank UK is to identify the genetic and environmental factors predisposing individuals to common diseases such as heart disease, cancer and mental illness. Biobank UK’s aims are The MRC states that this understanding would be used to controversial, its predict the likelihood that an individual would develop a science is disease so that medicines could be used to prevent its questionable, and onset rather than as a treatment for symptoms once a there is a lack of legal disease develops2. Lifestyle advice could also be targeted safeguards. at those identified as ‘genetically susceptible’ to future illness. However, this approach to disease prevention is highly controversial. Many scientists believe that prediction of future common illnesses by testing people’s genetic make- up is unlikely to be a successful or cost-effective means of disease prevention. “[The Director of the US National Human Genome Research Institute] and many others have outlined scenarios where all individuals have a battery of genetic tests early in life so that the knowledge of ‘susceptibility’ can be used to avoid development of disease. Biomedical sectors would profit from acceptance of the above approach, but it is doubtful whether it is the approach most likely to increase the health of populations.” Professor Patricia Baird, Department of Medical Genetics, University of British Columbia, Canada3.

Targeting medicines at Targeting medicines at those identified as ‘genetically those identified as susceptible’ (sometimes known as the ‘healthy ill’) also has ‘genetically serious implications. The potential costs of this approach susceptible’ may have never been properly assessed, but it may prove to be prove to be both both wasteful and unsafe (due to side-effects and poor wasteful and unsafe. compliance), ineffective (because medication does not tackle the underlying causes of disease), and extremely costly to the NHS (by vastly expanding the market for medicines for healthy people). There is also a danger of detracting from population-based approaches to disease prevention such as the need to tackle tobacco control, traffic pollution, health inequalities, and the growing incidence of obesity in children. If those identified as not ‘genetically susceptible’ become falsely reassured that they do not need to change their lifestyles this could also have serious negative impacts on public health. Neither the Government nor the MRC has made any assessment of the relative costs and benefits of a genetic approach to disease prevention, compared to alternative population-based measures (such as expanding the Government’s “fruit in schools” programme). GeneWatch believes that there should be an independent assessment of this issue and a full parliamentary debate about the potential implications for the NHS.

Biobank UK – good science? “The scientific value of focusing on gene-environment interactions has not been established, and in any case, the technical advantages of cohort studies over case-control studies in detection of statistical interactions between genetic and environmental effects are less clear than has been assumed.” David Clayton (Department of Medical Genetics, Cambridge University) and Professor Paul McKeigue (London School of
