Genes predict the brain’s reaction to smoking

Have you ever wondered why some people find it so much easier to stop smoking than others? New research shows that vulnerability to smoking addiction is shaped by our genes. A study from the Montreal Neurological Institute and Hospital – The Neuro, McGill University shows that people with genetically fast nicotine metabolism have a significantly greater brain response to smoking cues than those with slow nicotine metabolism.

Researchers link genetic mutation to psychiatric disease and obesity

Dr. Carl Ernst
McGill researchers have identified a small region in the genome that conclusively plays a role in the development of psychiatric disease and obesity. The key lies in the genomic deletion of brain-derived neurotrophic factor, or BDNF, a nervous system growth factor that plays a critical role in brain development.

To determine the role of BDNF in humans, Carl Ernst, PhD, from McGill’s Department of Psychiatry, Faculty of Medicine, screened over 35,000 people referred for genetic screening at clinics and over 30,000 control subjects in Canada, the U.S., and Europe. Continue reading

McGill researchers discover the cause of an inherited form of epilepsy

Dr. Gary Brouhard

Findings could open avenues for improved therapies for a range of conditions

Researchers at McGill University have discovered the cause of an inherited form of epilepsy. The disease, known as double-cortex syndrome, primarily affects females and arises from mutations on a gene located on the X chromosome. Continue reading

Discovery of a gene that causes Joubert Syndrome in the population of the Lower St. Lawrence region of Quebec

Jacques Michaud
May 10, 2012 – C5ORF42 was identified as the gene that causes Joubert Syndrome in a number of families in the Lower St. Lawrence region of Quebec where the causal gene had remained unknown since the initial description of the syndrome in 1969. This is what a study in the April issue of The American Journal of Human Genetics reveals. The study was conducted by researchers from the Sainte-Justine University Hospital Research Center and the Centre of Excellence in Neuromics of Université de Montréal’s (CENUM). Continue reading
