Professor Henry Houlden is a Professor of Neurology and Neurogenetics at UCL Queen Square Institute of Neurology and serves as the Clinical Lead for Neurogenetics at the National Hospital of Neurology and Neurosurgery in London. He plays a key role on the Genomics England board for rare diseases as part of the 100,000 Genomes Project. His clinical expertise covers neurological disorders, including Parkinson’s disease, multiple system atrophy (MSA), ataxia, DRPLA, dementias, leukodystrophies, spastic paraplegia, and neuromuscular conditions. His research focuses on neurogenetics, particularly Parkinson’s in underrepresented populations, using novel genomic approaches. He is interested in studying ethnic diversity in neglected populations and has contributed to the discovery of many disease genes. His work integrates long-read sequencing with functional validation to understand the genetic basis of neurological conditions, aiming to improve diagnosis and treatment. He has over 700 publications in leading scientific journals, advancing neurogenetics worldwide.
