About me:

Prof Andrew Hattersley FRS is an outstanding clinical scientist, who is distinguished for his contributions to the understanding of the genetics of diabetes and the application of that knowledge to clinical practice. He became Gillings Chair in Precision Medicine in 2015 and leads the Precision medicine initiative in Exeter working with both scientific and clinical colleagues.

He and Prof Sian Ellard set up and currently head the premier international research team working on monogenic diabetes and has played a major role in the UK research effort into the genetics of type 2 diabetes. He continues to work as a consultant physician in diabetes while at the same time leading a large research team. His research combines state-of-the-art molecular genetics with physiological and clinical investigations in patients. He uses the accidents of nature that cause monogenic diabetes to understand the critical role of the gene product in man, in a similar fashion to many laboratory scientists who study knockout animals. A key theme of his approach is that his scientific discoveries are rapidly and effectively translated into improvements in clinical care.

Interests:

Professor Andrew Hattersley is a clinical researcher whose work on diabetes combines state-of-the-art molecular genetics, physiological studies and clinical observations to generate important scientific insights. He is medically trained, still clinically active, and reknowned for his ability to translate his basic science discoveries into advances in patient care.

His medical degree was obtained at Cambridge (pre-clinical) and Oxford (clinical). After general medical training in London, he undertook post-graduate training in diabetes at the Hammersmith hospital and Birmingham. His scientific research career began as an MRC training fellow in Oxford in 1990, working with Professor Turner, Dr Wainscoat and Professor Weatherall on clinical, physiological and molecular biological aspects of maturity-onset diabetes of the young (MODY). This work led to the identification of glucokinase as the first gene to cause diabetes (simultaneously with a French group). It also instilled Hattersley with a life-long interest in monogenic diabetes. He continued this work as a lecturer in Birmingham for 2 years, and then moved to a senior lecturership and consultant physician post at Exeter (1995).

Hattersley rapidly transformed Exeter from a centre without a genetics lab to being the premier international centre for monogenic diabetes. He now leads a 29-person research team that integrates cutting-edge scientific research with an NHS diagnostic laboratory, and routine patient care in diabetes.

His major contribution in the past 10 years has been to define the genetic aetiology of monogenic diabetes and, by studying these patients, to improve our knowledge of the development, function and regulation of the insulin-secreting pancreatic beta-cells. This work, both independently and in collaboration with others, has led to the identification of >10 genes that cause neonatal diabetes. Discovery of the causal role of activating mutations in KATP channel genes in neonatal diabetes (2004) immediately led to the possibility that sulphonylurea drugs, which close the channel, might stimulate insulin secretion in these patients. Hattersley subsequently demonstrated that these drugs produce excellent glycaemic control without hypoglycaemia (2006). This work led to the rewriting of international guidelines for all patients diagnosed with diabetes before 6 months to include immediate genetic diagnosis. Hattersley now offers rapid, free, genetic testing patients with neonatal diabetes. As a result, >1200 patients from over 80 countries have now switched from insulin injections to oral sulphonylurea therapy.

Hattersley has developed and assessed biomarkers and diagnostic approaches for the diagnosis of MODY (2010-2013). His work on the treatment and management of the different subgroups of MODY has transformed international guidelines. Recent work has led to a greater understanding of the role and regulation of transcription factors in beta-cell development and function (2009-2013).

His work has not been confined to monogenic diabetes: from 1995-2008 he co-led the UK research effort to identify genetic polymorphisms that predispose to Type 2 diabetes including FTO the major polymorphism predisposing to obesity. Latterly, this work has provided novel insights into the relationship between birth weight and diabetes in later life (2007-2012). Current studies include the development and implementation of a personalised approach to the treatment of Type 2 diabetes.
