Rob Hegele, Scientist

Why I Became a Scientist

From my parents, I developed at an early age a great appreciation for academics and learning. I attended the University of Toronto and received my medical degree in 1981. Specialty training in Internal Medicine and Endocrinology was followed by four years of post-doctoral training, first at the Rockefeller University, New York City, in heart disease and cholesterol, and then in human genetics at the Howard Hughes Medical Institute in Salt Lake City, Utah. It was during my research fellowship in New York City that I became inspired to pursue research in genetics. With a strong belief in the power of human genetics and genomics to help solve fundamental problems related to human health and disease, my lab began researching the genetic basis of several human disorders, most notably several forms of dyslipidemia (high cholesterol) and type 2 diabetes.

Research Summary

Rob Hegele is an endocrinologist with an interest in lipidology and diabetes, who cares for >1700 patients. He is the Director of the Blackburn Cardiovascular Genetics Lab and London Regional Genomics Centre. He has trained many physicians in lipidology and several graduate students in human genetics. His laboratory has studied the genetic basis of diabetes and atherosclerosis in Canadian sub-populations and aboriginal communities. His lab discovered the molecular genetic basis of 14 human diseases, including hepatic lipase deficiency, Oji-Cree type 2 diabetes, familial partial lipodystrophy and endocrine-cerebro-ostedysplasia and has described >100 human mutations causing dyslipidemia, diabetes and atherosclerosis. He has published >450 original peer-reviewed articles and serves on numerous journal editorial boards, including Journal of Clinical Investigation, Circulation, Stroke, ATVB and Journal of Lipid Research. He has received numerous international awards recognizing his research and his work has been cited >9,000 times in the biomedical literature. He is listed in the ISI Web of Knowledge database as being in the top 1% of highly cited scientists in the world.

Research Questions and Disease Implications

Why do some individuals and families develop heart disease and stroke despite very clean living and healthy lifestyles?

Identification of new genes that can cause heart disease, stroke and such high risk conditions as diabetes, hyperlipidemia and hypertension.

Identification of new genes leads to new understanding of pathways for these diseases and is the first step in the development of new diagnostic methods and treatments.

Why are certain aboriginal groups in Canada so highly predisposed to developing diabetes?

Identification of new genes and the exacerbating environmental factors that cause diabetes can lead to new understanding of the underlying pathways and is the first step in the development of new diagnostic methods and treatments.

How is it that certain people can eat as much as they like and not gain any weight, while some others eat sparingly but cannot seem to lose weight?

Identification of new genes that create susceptibility to obesity can lead to new understanding of the underlying pathways and is the first step in the development of new diagnostic methods and treatments.
