- Canadian College of Medical Geneticists (CCMG)
Dr. Jessie Cameron is a Biochemical Geneticist and lab director of the Metabolic Disease lab in The Hospital for Sick Children.
She obtained her PhD from University College London, England, and has worked at The Hospital for Sick Children for over 20 years.
Prior to her current role, she worked as a postdoctoral graduate and then a Research Associate in the lab of Dr Brian Robinson which has served as a pivotal hub for the study and diagnosis of mitochondrial disease in Canada for over 35 years.
My main area of focus has been the identification of novel mitochondrial inborn errors of metabolism.
I have worked extensively on many known mitochondrial disease genes, identifying new mutations and further characterizing established diseases. My research has always been tightly connected with clinical diagnosis. I have had success in identifying novel diseases based on researching clinical and phenotypic data, and applying my knowledge of mitochondrial pathways to determine which experimental techniques will best identify key information.
I have identified the first patients in the world for four diseases: PDP1 deficiency, affecting the activation of pyruvate dehydrogenase complex; NFU1 and BOLA3 deficiencies, affecting the iron-sulfer cluster biogenesis pathway, which has implications on many aspects of mitochondrial function, including both respiratory chain and 2-oxoglutarate dehydrogenase complex functioning and AGK deficiency, a novel cause of 3-Methylglutaconic Aciduria affecting mitochondrial signalling and phospholipid biosynthesis.
I have identified the second patients in the world for two other diseases, TMEM70, another form of 3-Methylglutaconic Aciduria affecting ATP synthase biogenesis and GYS1 (Glycogen Storage Disease 0).
