Shamima Rahman (born 1964) is a Nigeria-born British paediatrician, scientist, and academic. She is the professor of paediatric metabolic medicine at the University College London Great Ormond Street Institute of Child Health and an honorary consultant at Great Ormond Street Hospital, London. Her research focuses on elucidating the genetic basis for paediatric mitochondrial and rare metabolic diseases, and developing novel pharmacological and genetic therapies to address these currently incurable disorders.[1][2]
Rahman's parents, after qualifying as doctors, worked in northern Nigeria close to the Sahara desert, where she was born in 1964. When she was a few months old, the family emigrated to the United Kingdom so her father could train in tropical medicine at the London School of Hygiene and Tropical Medicine in Bloomsbury. Since her parents were junior doctors, undertaking six-monthly contractual engagements, the family moved a lot when Rahman was a child. She attended ten different primary schools, before joining the Nottingham Girls' High School (NGHS), a private girls-only day school in Nottinghamshire, England, in 1975. By the time she joined NGHS, her father was working as a consultant physician and later became the medical director of his hospital. Her mother, having attended medical school in the 1950s with only a handful of women, eventually became a consultant anaesthetist. According to Rahman, institutionalised racism impeded her parent's career progression.[3]
Rahman's intake at NGHS coincided with the termination of the Direct Grant Scheme, under which a quarter of enrolments in the England and Wales secondary schools were directly funded by the central government. After coming into power in 1974, Labour enacted the Direct Grant Grammar Schools (Cessation of Grant) Regulations 1975, requiring schools to choose whether to operate as independent schools without grant or comprehensive schools maintained by Local Education Authorities (LEA).[4] Despite NGHS choosing to become independent, Rahman secured a full scholarship to attend the school. She was the only muslim student in her cohort, and recalled being uncomfortable with Christian-focused religious education; as a result, she stopped going to the school assemblies. She travelled to NGHS by bus, and was unable to participate in after-school extracurricular activities owning to the long commute. Rahman credits her mother was encouraging her to pursue medicine. The school supported her preparation for Oxbridge.[3]
In the late 1980s, Rahman trained in medicine at the University of Oxford, England. While pursuing her undergraduate degree, she worked in a in the Haemophilia centre laboratory which introduced her to the prospect of medical research. At that time, her focus was more on becoming a hands-on doctor rather than studying for a doctorate degree. She was awarded the 1985 Martin Wronker Prize for Medicine for her performance in pre-clinical medicine.
After qualifying as a doctor in 1988, she worked as a house officer for 120 hours a week, spending alternate nights on call, for a stipend of £9,000. She later trained in paediatrics at the Royal Hospital for Sick Children, Edinburgh and Great Ormond Street Hospital (GOSH), London. While at Great Ormond Street, she was awarded a scholarship by the Royal Children's Hospital Research Foundation to spend a year at the Murdoch Institute in Melbourne, Australia.[3][5]
Rahman returned to England in 1994 and completed her paediatric training at the John Radcliffe Hospital, Oxfordshire before joining the Medical Research Council clinical training fellowship at the UCL Great Ormond Street Institute of Child Health (UCL ICH), London to undertake a PhD in molecular medicine, for which she studied the molecular basis of cytochrome c oxidase deficiency in childhood under the expert supervision of James Leonard and Anthony Schapira.[6][2] She also received additional funding for her doctoral thesis work from Children Living with Inherited Metabolic Diseases (formerly known as Research Trust for Metabolic Diseases in Children).[6]
In 2000, during a Clinical Lectureship at the UCL ICH, Rahman completed her specialist training in paediatric metabolic medicine, and founded the Mitochondrial Research Group for improved diagnosis and management of mitochondrial and metabolic diseases presenting in children. In 2006, she was awarded a Department of Health (DH)-Higher Education Funding Council for England (HEFCE) Best Research for Best Health Clinical Senior Lectureship.[2][7] She was subsequently promoted to reader at UCL ICH and then professor in 2014.[8] She was selected for two fellowships at the Royal College of Paediatrics and Child Health and Royal College of Physicians in 2008 and 2011 respectively.[3][5]
Research
In 1999, Rahman was part of the research team funded by Wellcome Trust that reported the "first missense mutation in the mtDNA gene for subunit II of cytochrome c oxidase (COX)." The study identified the mutation in a 14-year-old boy suffering from proximal myopathy and lactic acidosis.[9]
She runs the Mitochondrial Research Group at UCL ICH, which she founded in 2000, that focuses on improving the "outcomes for children with mitochondrial and other metabolic diseases" through the discovery of mitochondrial disease genes, development of novel computational diagnostic strategies and therapeutic approaches in the absence of effective treatments.[10] The Group has conducted several long-term projects that implement an integrative genomics approach to "identify novel nuclear genes and gene variants responsible for human mitochondrial disease."[10] This includes deep phenotyping of patients, homozygosity mapping, sequence analysis of candidate genes, and high throughput 'next generation' sequencing methods, as well as developing and establishing novel bioinformatics pipelines, and multiple functional studies to uncover the pathogenicity of disease-causing mutations. In addition to elucidating new disease mechanisms, the Group has discovered new disease genes, in particular a complex I assembly factor and genes needed for mitochondrial DNA maintenance, biosynthesis of coenzyme Q10 and mitochondrial homeostasis.[10] A number of small molecule therapies for mitochondrial disease have also been evaluated, including vitamins and cofactors, decanoic acid, and nonsense readthrough agents; the Group is in the process of developing a gene therapy programme to address these disorders. Rahman currently leads an National Institute for Health and Care Research (NIHR)-funded study on ClinGen gene curations and contributes to ClinVar variant curations for primary mitochondrial diseases.[10][11][12]
Since its inception, the projects undertaken by the Group have provided genetic diagnoses for hundreds of patients referred from and beyond GOSH, leading to an increased diagnostic rate in a research setting (from 5 percent 20 years ago to approximately 70 percent in the present day).[10] They have also contributed to the development of in silico resources, such as the international classification of inherited metabolic disease (ICIMD) and the Leigh Syndrome Map, for mitochondrial and other inherited metabolic diseases.[13][14]
Teaching
Since 1997, Rahman has been teaching on the annual Practical Neurology Study Days at UCL ICH. She also delivers regular clinical teaching at Great Ormond Street Hospital across the metabolic, neurology and critical care departments.[15]
Rahman was appointed as the professor of paediatric metabolic medicine at UCL's Genetics and Genomic Medicine department in 2014.[3][5] She has supervised more than 30 PhD, MSc and BSc students during her career. She has also been invited to conduct over 150 national and international lectures.[15]
Other notable engagements
From 2008 to 2019, Rahman was the founding member of Society for the Study of Inborn Errors of Metabolism (SSIEM), and served as a Senior Advisor to the Society's Education and Training Committee (ETAC), delivering 12 annual SSIEM Academies, an ongoing 4-year rolling programme which has trained several hundred international physicians and biochemists in inherited metabolic disease.[5]
Rahman works as an assessment advisor to the Paediatric Inherited Metabolic Medicine Specialty Advisory Committee of the Royal College of Paediatrics and Child Health, where she was previously a Training Advisor. Since 2008, she had also been an honorary Consultant at Great Ormond Street Hospital for Children, London, funded by NHS Foundation Trust, where she focuses on children with primary mitochondrial diseases.[5][15] She acts as the international councillor to Mitochondrial Medicine Society (UK)[16] and special advisor to Human Fertilisation and Embryology Authority (HFEA). She is a member of the medical advisory board for Lily Foundation, Freya Foundation, and French Muscular Dystrophy Association.[17][5] She heads the mitochondrial subdomain of Genomics England's Clinical Interpretation Partnership, and is the mitochondrial subnetwork lead of the European Reference Network for Hereditary Metabolic Disorders (MetabERN).[17] She's part of the steering committee for Collaborative International Leigh Syndrome Task Force and James Lind Alliance's Rare Mitochondrial Disorders Priority Setting Partnership.[5]
According to Rahman, her ethnicity has posed a greater barrier professionally than her gender, although she believes women "have a very important voice and [their] voice is starting to be heard." She acknowledges the persisting inequalities in medicine, especially related to the gender pay gap. She supports diversity and inclusion in her work, and was part of the UCL GOSICH team that won the Equality Challenge Unit (ECU)'s Athena SWAN charter Silver award in 2013.[3]
