The Wellcome Trust Centre for Mitochondrial Research is built on our long standing clinical and scientific expertise in mitochondrial disease. We are totally committed to provide the best of care for our patients. We have very close links to the NHS Highly Specialised NHS Service for Rare Mitochondrial Disorders of Adults and Children. This Clinical Service is based within the Newcastle upon Tyne Hospitals NHS Foundation Trust and provides care for patients throughout the UK both in terms of diagnosis and management. It is led by Professor Doug Turnbull for adults and Dr Robert McFarland for children. There is a diagnostic laboratory led by Professor Rob Taylor providing tests for both biochemical and genetic diagnosis.
