JLernerEllisDr Jordan Lerner-Ellis is Head of Advanced Molecular Diagnostics at Toronto’s Mount Sinai Hospital, Sinai Health System. His laboratory provides clinical diagnostic services for hereditary breast, ovarian and colon cancer, and other genetic testing areas, for downtown Toronto and the province of Ontario. He holds the position of Assistant Professor in the University of Toronto’s Department of Laboratory Medicine and Pathobiology and Clinician Scientist at the Lunenfeld-Tanenbaum Research Institute.

While completing his PhD in human genetics at McGill University, Dr. Lerner-Ellis discovered or co-discovered four genes that cause inborn errors of Vitamin B12 metabolism when mutated. He continued his studies at the Children’s Hospital in Basel, Switzerland before moving on to a postdoctoral fellowship in Molecular Biology at Harvard University, the Massachusetts General Hospital, and in Medical and Population Genetics at the Broad Institute. Following his postdoctoral studies, Dr. Lerner-Ellis completed the Clinical Molecular Genetics training program at Harvard Medical School, Brigham and Women’s Hospital and is certified as a diplomate of the American Board of Medical Genetics.

Dr Jordan Lerner-Ellis’ core interest is in molecular diagnostics as currently applied to breast and colon cancer. His research is focused on improving genetic testing through greater reliance on new sequencing technologies. A concurrent aim of his research is to integrate genome sequencing into the general practice of medicine. Dr Lerner-Ellis is active in National and International data sharing and variant interpretation efforts aimed at improving our understanding of the relationship between DNA variants and disease.
