Our research

 Leukodystrophies and genetically-determined leukoencephalopathies are a group of rare genetic diseases affecting previously healthy individuals. Most of these diseases are degenerative and affect primarily children. Leukodystrophies and genetically-determined leukoencephalopathies are caused by abnormalities in myelin or white matter, which is involved in protecting neurons, or nerve cells, and ensure the rapid conduction of nerve impulses. Dr. Geneviève Bernard’s research program addresses the main knowledge gaps for this group of diseases and includes the following broad aims: (1) clinical and radiological characterization of leukodystrophies, (2) description of their natural history, (3) description of their impact on patients and their families (quality of life, stress), (4) identification of new causal genes, (5) study of their pathophysiology, (6) development of novel therapeutic strategies and, (7) development and participation in future therapeutic trials.

Dr Geneviève Bernard

Dr. Geneviève Bernard received her Medical Degree (2002) and Master’s degree in Neurosciences (2003) from Université de Montréal. She completed her residency in Pediatric Neurology at McGill University (2008) and her fellowship in Neurogenetics and Movement Disorders at Université de Montréal (2011) under the supervision of Pr. Bernard Brais, Pr. Guy A Rouleau and Dr. Sylvain Chouinard. She started her career as an independent investigator and pediatric neurologist in October 2011 at the Montreal Children’s Hospital of the McGill University Health Center (MUHC) and MUHC Research Institute. She is currently an Associate Professor at McGill University, in the Departments of Neurology and Neurosurgery, Pediatrics and Human Genetics. She is a member of the Medical Genetics Division at the MUHC. Dr. Bernard and her team, together with her international collaborators, discovered the three genes responsible for 4H leukodystrophy and published, in collaboration with Dr. Nicole Wolf and numerous international collaborators, the largest clinical, radiological and genetic characterization study on this disorder. Dr. Bernard published more than 75 peer-reviewed publications, including some in high impact factor journals, several book chapters and numerous abstracts. She is the Canadian representative on several international consortia, including the Global Leukodystrophy InitiAtive (GLIA), ALD connect and the tRNA synthetases disorders research consortia.
