High-throughput genotyping has revolutionised the genome-wide search for associations between genetic variants and disease. Professor Sir Edwin Southern of the University of Oxford's Biochemistry Department invented the highly cost-effective array-based method of analysing genetic variation based on hybridisation between probes and samples on glass slides or `chips'. The spin-out company Oxford Gene Technology (OGT) founded by Southern in 1995 licenses the patent to manufacturers of `single nucleotide polymorphism (SNP) chips', including Illumina and Agilent, a global business exceeding $500M per year. Southern has continued to refine and extend this technology to increase its speed, efficiency and cost-effectiveness. This revolutionary technology has widespread applications such as prediction of individual risk, development of new drugs, provision of personalised treatments, and increased cost-effectiveness of clinical trials. Licence revenues fund R&D within OGT, and endow charitable trusts supporting primary school science education in the UK and crop improvement in the developing world.
This case study describes both economic and healthcare benefits that have resulted from a new DNA (gene) sequencing technique known as SOLiD sequencing. Through the 1990s until the present, Cosstick (University of Liverpool since 1984) has both developed the synthesis and studied the properties of chemically modified DNA in which a single oxygen atom is replaced by sulfur; we have termed this a 3'-phosphorothiolate (3'-sp) modification. Chemically prepared DNA containing the 3'-sp modification is a key enabling component of the Applied Biosystems SOLiD DNA sequencing instrument which is able to produce extremely rapid, cost-effective and exceptionally accurate DNA sequence information. The impact of this very powerful sequencing technology extends beyond economic benefits as it has many healthcare applications which have impacted medical practice.
Research in the School of Mathematics & Statistics in the University of Glasgow has been influential in answering a long-standing question: where do we come from? The fleshing-out of the 'out of Africa' theory has been the focus of two documentary series, The Incredible Human Journey and Meet the Izzards, and has generated income for DNA testing companies in the UK and US by enabling them to offer `deep DNA' tests revealing one's roots from far back in history. The Incredible Human Journey aired on BBC 2 in 2009, reaching 10.2 million viewers altogether, has been watched 100,000 times on YouTube and was broadcast in shorter format in Australia and Canada before being released as a DVD. Meet the Izzards was broadcast on BBC 1 in 2013 to over 3 million people.
Hagan Bayley's research on nanopore sensing for DNA sequencing at the University of Oxford led to the formation of the spin-out company Oxford Nanopore Technologies Ltd (ONT) in 2005. Since 2008, ONT has raised £ 97.8M to support research and product development. This level of investment arises as a direct result of the pioneering technology ONT has developed, based on research in the UOA, which has the potential to revolutionise DNA sequencing and other single molecule analyses. ONT currently employs 145 people, nearly six times as many as in 2008, and was recently valued at $ 2 billion. Evidence from ONT was used in a 2009 House of Lords report on genomic medicine, demonstrating ONT's position at the forefront of this new technology.
Research by Professor David Brook on inherited disorders has made a major contribution to the human genetics field. The work involved gene identification and mutation detection for genotype/phenotype correlation analysis in patients, which has led to the development of diagnostic tests for inherited conditions including myotonic dystrophy type 1 (DM1), Holt-Oram Syndrome (HOS), and campomelic dysplasia (CD). The tests have benefitted patients in the UK and throughout the rest of the world and in many cases they have been used as the definitive diagnostic measure. The assays developed have also been used in affected families for prenatal diagnosis to enable informed reproductive decisions.
This case study describes the impact of discoveries by Griffin and Handyside on the universal detection of genetic disease in IVF embryos. The team used basic research to develop practicable new techniques now employed in IVF clinics around the world and culminating in a process named "Karyomapping". The impacts are far-reaching and significant: when applied to families at risk of transmitting genetic disorders the process has resulted in live births of unaffected children. The positive results of the discoveries have extended beyond clinical applications: Adaptations of the technology are now being translated to farm animal breeding regimes to improve meat yields and reduce environmental concerns. Impact also includes new product development and wealth generation, job creation, education, and influence on public policy through HFEA, plus widespread public engagement and communication.
Impact on commerce: A patented technique for separating methylated and non-methylated DNA has been licensed and a kit brought to market, along with other commercial reagent licenses.
Impact on health and welfare: The demonstration that two mechanisms of epigenetic gene regulation, DNA methylation and histone acetylation, are linked, has led to trials of separate drugs known to affect each mechanism as a combined treatment for high-risk patients with myelodysplastic syndromes (MDS).
Beneficiaries: Companies have gained commercial benefit from licensing UoE IP to market products. High-risk MDS patients will benefit from improved treatment.
Significance and Reach: Commercial earnings across 4 companies from international sales in the period estimated at over [text removed for publication], mainly since 2010. Commercial significance includes the first commercially-available technique for separating methylated and non-methylated DNA.
The incidence of MDS is estimated at 3-4 cases diagnosed annually per 100,000 of the population in Europe (an estimated 26,000 individuals) and up to 20,000 new diagnoses per year in the USA. Incidence increases with age — up to 15 new cases annually per 100,000 in individuals aged over 70 years. MDS occurrence is increasing as the age of the population increases, so the significance of new therapies is high.
Attribution: All research was led by Adrian Bird at UoE. Reik (Babraham Institute) contributed to development of one of the licensed antibodies.
Bacteria of the Clostridium genus are of pathogenic, medical and industrial importance. Development by University of Nottingham School of Life Science researchers of three patented methods for genetic manipulation of clostridial species has led to licensing agreements for commercial exploitation of the methodology to enhance strains for chemical commodity and biofuel production and for targeted cancer therapy. These methods are providing significant world-wide impact by facilitating commercial R&D investment and technology developments in fields ranging from healthcare, through chemicals manufacture, to the environment.

Research by Chadwick has influenced research protocols and policies regarding the ethical consequences of collecting DNA for research. Her impact is most visible in the Personal Genome Project, and the work of the Nuffield Council on Bioethics, UN Food and Agriculture Organisation, Human Genome Project and H3Africa. Her contributions to discussions and documents resulted in changes to how consent is gained from DNA donors. In particular, the changes address important issues that she raised regarding the practicality and acceptability of the undertakings made in current consent protocols about confidentiality and the future use of data. Chadwick's underpinning research claims relate to the fact that genetic information, and the attendant genetic technology, are derived from, and significant to, populations as a whole. She maintains that biotechnological advances are changing our ethical values, particularly regarding conflicts between personal interests and large-group needs. For her, practical ethics cannot apply normative ethical concepts and theories arising from abstract philosophical reasoning. Rather, the conceptual and theoretical structures themselves must be developed through philosophical engagement with the scientific details of the project. Her collaboration with bodies responsible for the protocols of consent reflects a `bottom-up' moral philosophy rather than the traditional `top-down' theory-driven approach.
The Ethics of Patenting DNA was a Nuffield Council on Bioethics Report by a working party of which Thomas Baldwin was a member with responsibility for providing the ethical framework for the report. The report was published in 2002 and its initial impact occurred in the 2002-2005 period; but it has had continuing impact during the current period on legal and political debates concerning the granting of patents on DNA sequences to pharmaceutical and biotechnology companies and to universities. More generally it continues to have a significant impact on policy formation in this much disputed area.
