Professor Patrick Francis Chinnery, FRCP, FRCPath, FMedSci, is a neurologist, clinician scientist, and Wellcome Trust Principal Research Fellow based in the Medical Research Council Mitochondrial Biology Unit and the University of Cambridge, where he is also professor of neurology and head of the department of clinical neurosciences. [1] [2] [3]
In 2023 he was appointed executive chair of the Medical Research Council (United Kingdom). [4] He is co-chair of the National Institute for Health and Care Research BioResource for Translational Research in Chronic and Rare Diseases. [5]
Chinnery attended Medical School at Newcastle University, where he graduated with a Bachelor of Medical Science degree in 1989 with first class honours; and Bachelor of Medicine, Bachelor of Surgery with honours in 1992. He went on to complete his PhD in mitochondrial genetics in 2000 whilst training in clinical neurology and neurogenetics. [6]
Chinnery trained as a physician and neurologist in the north east of England, becoming a member of the Royal College of Physicians in 1995, and completing his specialist clinical training in neurology 2002 when he was appointed Honorary Consultant Neurologist at Newcastle upon Tyne Hospitals NHS Foundation Trust. He specializes in inherited disorders of the nervous system (neurogenetics) and established the north of England regional neurogenetics service between 2002 and 2015.
In 2015 he moved to the University of Cambridge as Professor of Neurology and Head of the Department of Clinical Neurosciences within the School of Clinical Medicine. He practices as a neurologist at Addenbrooke's Hospital. He became a Fellow of Gonville and Caius College in 2017 where he is Director of Studies in Clinical Medicine.
His research focuses on understanding the role of mitochondria in human disease. He has identified the genetic basis of several new diseases caused by genetic mutations affecting the genetic code within mitochondria (mtDNA) and the nuclear genome which code for mitochondrial proteins. In the first genetic epidemiology study he showed that mtDNA diseases were much more common than expected. [7] People with mtDNA diseases often harbour a mixture of normal and abnormal mtDNA (heteroplasmy). His group showed that most healthy people also carry heteroplasmic mtDNA mutations, but at very low levels. [8] They showed that a dramatic reduction in mtDNA levels within female germ cells during embryonic development leads to major shifts in heteroplasmy levels over one generation (the mitochondrial genetic bottleneck). [9] [10] The bottleneck explains how low level heteroplasmy in carriers can lead to mitochondrial diseases within one generation, and the different severity of mtDNA disease seen in siblings within the same family. Carrying out the first large-scale study in the UK 100,000 genomes project, he showed that the nuclear genetic background also influences the inheritance pattern of mtDNA mutations. [11] He also showed that genetic variation of mtDNA influences the risk of developing common diseases and many human physiological traits, including kidney and liver function. [12]
He has been supported by Wellcome Trust research fellowships since 1995, most recently as a Wellcome Principal Research Fellow. Additional research support has come from the Medical Research Council / UK Research and Innovation, and the National Institute for Health Research.
Chinnery was Director of the National Institute for Health Research (NIHR) Newcastle Biomedical Research Centre from 2008 to 2015, leading a doubling of funding. Since 2012 he has been co-chair of the NIHR Rare Diseases Translational Research Collaboration, then the NIHR BioResource with John Bradley. [13]
In 2010 he was appointed Director of the Institute of Genetic Medicine at Newcastle University. In 2015 he moved to the University of Cambridge as Professor of Neurology and Head of the Department of Clinical Neurosciences. [14]
In 2018 he became Clinical Director of the Medical Research Council within UK Research and Innovation, where is he was responsible for clinical translational research programmes.
He has advised to two UK Government Chief Medical Advisors, [15] and ministers and Secretaries of State within the Department of Health and Social Care and the Department of Business Energy and Industrial Strategy. In 2020 he was appointed National Core Study Lead for COVID-19 therapeutics by the UK Government Chief Scientific Advisor Sir Patrick Vallance. [16] In 2020 he was asked by UK Government Chief Medical Advisor Professor Chris Whitty to established and chair the UK COVID-19 Therapeutics Advisory Panel (UK-CTAP) which recommended drugs into the UK national clinical trial platforms. [17]
Chinnery was awarded several prizes as a training neurologist and researcher, twice being awarded the Charles Symonds Prize by the Association of British Neurologists (1997, 2002). In 2009 he was the youngest elected member of the Academy of Medical Sciences, who awarded him the Foulkes Foundation Medal in 2011. [18] He has been a Fellow of the Royal College of Physicians since 2006, and a Fellow of the Royal College of Pathologists since 2007. In 2010 he became a NIHR Senior Investigator (now emeritus), and is a corresponding member of the American Neurological Association. [19] In 2022 he was awarded the Galen Medal by the Worshipful Society of Apothecaries. [20] He was elected a Fellow of the Royal Society in 2024. [21]
Anita Elizabeth Harding was an Irish-British neurologist, and Professor of Clinical Neurology at the Institute of Neurology of the University of London. She is known for the discovery with Ian Holt and John Morgan-Hughes of the "first identification of a mitochondrial DNA mutation in human disease and the concept of tissue heteroplasmy of mutant mitochondrial DNA", published in Nature in 1986. In 1985 she established the first neurogenetics research group in the United Kingdom at the UCL Institute of Neurology.
Mitochondrial disease is a group of disorders caused by mitochondrial dysfunction. Mitochondria are the organelles that generate energy for the cell and are found in every cell of the human body except red blood cells. They convert the energy of food molecules into the ATP that powers most cell functions.
Leigh syndrome is an inherited neurometabolic disorder that affects the central nervous system. It is named after Archibald Denis Leigh, a British neuropsychiatrist who first described the condition in 1951. Normal levels of thiamine, thiamine monophosphate, and thiamine diphosphate are commonly found, but there is a reduced or absent level of thiamine triphosphate. This is thought to be caused by a blockage in the enzyme thiamine-diphosphate kinase, and therefore treatment in some patients would be to take thiamine triphosphate daily. While the majority of patients typically exhibit symptoms between the ages of 3 and 12 months, instances of adult onset have also been documented.
The Medical Research Council (MRC) is responsible for co-coordinating and funding medical research in the United Kingdom. It is part of United Kingdom Research and Innovation (UKRI), which came into operation 1 April 2018, and brings together the UK's seven research councils, Innovate UK and Research England. UK Research and Innovation is answerable to, although politically independent from, the Department for Business, Energy and Industrial Strategy.
Heteroplasmy is the presence of more than one type of organellar genome within a cell or individual. It is an important factor in considering the severity of mitochondrial diseases. Because most eukaryotic cells contain many hundreds of mitochondria with hundreds of copies of mitochondrial DNA, it is common for mutations to affect only some mitochondria, leaving most unaffected.
Homoplasmy is a term used in genetics to describe a eukaryotic cell whose copies of mitochondrial DNA are all identical. In normal and healthy tissues, all cells are homoplasmic. Homoplasmic mitochondrial DNA copies may be normal or mutated; however, most mutations are heteroplasmic. It has been discovered, though, that homoplasmic mitochondrial DNA mutations may be found in human tumors.
Leber's hereditary optic neuropathy (LHON) is a mitochondrially inherited degeneration of retinal ganglion cells (RGCs) and their axons that leads to an acute or subacute loss of central vision; it predominantly affects young adult males. LHON is transmitted only through the mother, as it is primarily due to mutations in the mitochondrial genome, and only the egg contributes mitochondria to the embryo. Men cannot pass on the disease to their offspring. LHON is usually due to one of three pathogenic mitochondrial DNA (mtDNA) point mutations. These mutations are at nucleotide positions 11778 G to A, 3460 G to A and 14484 T to C, respectively in the ND4, ND1 and ND6 subunit genes of complex I of the oxidative phosphorylation chain in mitochondria.
Mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) is one of the family of mitochondrial diseases, which also include MIDD, MERRF syndrome, and Leber's hereditary optic neuropathy. It was first characterized under this name in 1984. A feature of these diseases is that they are caused by defects in the mitochondrial genome which is inherited purely from the female parent. The most common MELAS mutation is mitochondrial mutation, mtDNA, referred to as m.3243A>G.
MERRF syndrome is a mitochondrial disease. It is extremely rare, and has varying degrees of expressivity owing to heteroplasmy. MERRF syndrome affects different parts of the body, particularly the muscles and nervous system. The signs and symptoms of this disorder appear at an early age, generally childhood or adolescence. The causes of MERRF syndrome are difficult to determine, but because it is a mitochondrial disorder, it can be caused by the mutation of nuclear DNA or mitochondrial DNA. The classification of this disease varies from patient to patient, since many individuals do not fall into one specific disease category. The primary features displayed on a person with MERRF include myoclonus, seizures, cerebellar ataxia, myopathy, and ragged red fibers (RRF) on muscle biopsy, leading to the disease's name. Secondary features include dementia, optic atrophy, bilateral deafness, peripheral neuropathy, spasticity, or multiple lipomata. Mitochondrial disorders, including MERRFS, may present at any age.
The MRC Mitochondrial Biology Unit is a department of the School of Clinical Medicine at the University of Cambridge, funded through a strategic partnership between the Medical Research Council and the University. It is located at the Addenbrooke’s Hospital / Cambridge Biomedical Campus site in Cambridge, England. The unit is concerned with the study of the mitochondrion, as this organelle has a varied and critical role in many aspects of eukaryotic metabolism and is implicated in many metabolic, degenerative, and age-related human diseases.
MT-ND6 is a gene of the mitochondrial genome coding for the NADH-ubiquinone oxidoreductase chain 6 protein (ND6). The ND6 protein is a subunit of NADH dehydrogenase (ubiquinone), which is located in the mitochondrial inner membrane and is the largest of the five complexes of the electron transport chain. Variations in the human MT-ND6 gene are associated with Leigh's syndrome, Leber's hereditary optic neuropathy (LHON) and dystonia.
