Dr. Gan-Or came to The Neuro as a post-doctoral fellow in the lab of Dr. Guy Rouleau and was appointed principal investigator in 2016. He is investigating REM sleep behavior disorder and Parkinson's disease.
Dr. Ziv Gan-Or completed his MD and PhD at Tel-Aviv University, with a major interest in lysosomal related genes and their role in the development and progression of Parkinson’s Disease. In his current work at the MNI, he utilizes advanced genotyping and next-generation sequencing technologies to further study the genetic background of Parkinson’s Disease. Dr. Gan-Or’s lab is also interested the genetics of a specific prodromal condition – REM sleep behavior disorder. Individuals who suffer from REM sleep behavior disorder will most likely develop a neurodegenerative disease: either Parkinson’s Disease, dementia with Lewy bodies or multiple system atrophy. By identifying the genetic background of REM sleep behavior disorder and its progression to one of these neurodegenerative disorders, Dr. Gan-Or aims to identify novel pathways and mechanisms that may help developing treatment. His research also focuses on other neurological disorders, such as hereditary spastic paraplegia and restless legs syndrome. Although there are more than 60 genes already identified in hereditary spastic paraplegia, about 50% of the families remain without genetic diagnosis, suggesting that many more genes associated with hereditary spastic paraplegia are still do be discovered.
