To ask the Secretary of State for Health and Social Care, whether he plans to increase the level of life-long provision of services for adults with mitochondiral diseases.

NHS England commissions a rare mitochondrial disorders service for adults and children from three centres: Oxford University Hospitals NHS Trust, The Newcastle upon Tyne Hospitals NHS Foundation Trust and University College London Hospitals NHS Foundation Trust. The service provides specialist histochemical, biochemical and molecular genetics testing and multi-disciplinary outpatient assessment, including access to cardiology, ophthalmology, diabetology, neurology, genetics, physiotherapy and speech therapy. The service provides clinical management and holistic advice to patients and their families and carers as well as taking part in research into these diseases. The service provides lifelong supportive care for patients with mitochondrial disease. There are no plans to expand the service.
