New genes identified with key role in the development of severe childhood epilepsies

In the largest collaborative study so far, an international team of researchers, including scientists from VIB and Antwerp University identified novel causes for severe childhood epilepsies. The researchers analyzed the genetic information of 356 patients and their parents. ... Full story

CUHK Multidisciplinary Research Team Hunts Down Gene Mutation that Causes a Novel Form of Spinocerebellar Ataxia

After three years of persistence and hard work, a multi-disciplinary research team led by Prof. H.Y. Edwin Chan of the School of Life Sciences at The Chinese University of Hong Kong (CUHK) has identified a novel genetic mutation that leads to spinocerebellar ataxia (SCA). The work has been published in the September issue of Journal of Medical Genetics, a leading international peer-reviewed journal in human genetics. This is the first time that researchers from Hong Kong have identified a novel gene mutation that leads to SCA. ... Full story

Gene protects teens from alcohol problems but not if they drink with friends

By Jim Dryden - Among more than 1,500 adolescents who had consumed at least one drink before age 18, researchers have found that although a gene variant prevents some young drinkers from developing alcohol problems, the gene’s protective effects can vanish in the presence of other teens who drink. ...

Evidence of Genetic Link to PTSD in Soldiers Exposed to Childhood Trauma

While abnormalities in the adrenergic and noradrenergic systems, both integral in the fight-or-flight response, are thought to play a role in the development of post-traumatic stress disorder (PTSD), until now there has been no genetic evidence of this connection. ... Full story
