Ny Hoang

Title: Genetic Counsellor, Division of Clinical and Metabolic Genetics
Designations: MS, CGC
U of T Positions: Lecturer, Department of Molecular Genetics


Ny Hoang is an ABGC-certified genetic counsellor in the Autism Research Unit of the Genetics and Genome Biology program. She joined SickKids after receiving her master of science in Human Genetics from Sarah Lawrence College in 2011.

In her current role, she specializes in the genetic contributions to autism spectrum disorder and other neurodevelopmental disorders.  She provides feedback to research participants involved in genomic sequencing studies and discusses the significance and implications of genetic results for both participants and the research community.  Ny is a member of Genomic Research Genetic Counsellors at SickKids, a Lecturer in the M.Sc. Genetic Counselling Program at the University of Toronto, and an administrative member of Genetic Counsellors of Ontario. Her areas of research interest include genomic technologies, autism spectrum disorder, and knowledge translation.


Ny Hoang’s research focus is on the genetic contribution to autism spectrum disorder (ASD) and other neurodevelopmental disorders. Over the past eight years, she has been part of Canada’s largest genome sequencing study in ASD. Using cutting-edge technologies, the study has identified hundreds of genetic risk factors for ASD and related conditions. This research aims to better understand the complex genetic etiology, the variable clinical presentations, and the relationship between the two in ASD. The hope is that this knowledge will lead to early detection and intervention, targeted therapies, and better quality of life for individuals with ASD.
