Research Discovers Three New Genetic Risk Markers of Depression

Hinxton, (Scicasts) — A study published today (March 2) in the American Journal of Psychiatry details the discovery of three additional genetic risk markers for depression, building on the discovery of two genetic risk factors in 2015.

Researchers at Virginia Commonwealth University, the European Bioinformatics Institute (EMBL-EBI) and Wellcome Sanger Institute have found that the contribution of genetic variations to depression may differ between people who have experienced serious adversities in their life and those who haven’t. By carrying out a genome-wide ...

Major mental illnesses unexpectedly share brain gene activity, raising hope for better diagnostics and therapies

Mental illness affects one in six U.S. adults, but scientists’ sense of the underlying biology of most psychiatric disorders remains nebulous. That’s frustrating for physicians treating the diseases, who must also make diagnoses based on symptoms that may only appear sporadically. No laboratory blood test or brain scan can yet distinguish whether someone has depression or bipolar disorder, for example.

Now, however, a large-scale analysis of postmortem brains is revealing distinctive molecular traces in people with mental illness. This week, an ...

Featured Student: Eric Vornholt

Eric Vornholt is a Ph.D. student in the Psychiatric, Behavioral, and Statistical Genetics program at Virginia Commonwealth University. He has always been interested in psychology and as an undergraduate at The University of Arizona, expanded this interest to include genetics and neuroscience. As part of his coursework, Mr. Vornholt became keenly aware of how much these two fields intersect, but also how much this intersection is under-studied. After coming to VCU, his primary research interest naturally became ...

VCU, Swedish study finds genetics and environment equally contribute to major depression transmission

Parent-to-offspring transmission of risk for major depression is the result of genetic factors and child-rearing experiences to an approximately equal degree, according to a new study conducted by researchers at Virginia Commonwealth University and Lund University in Sweden. The discovery is the result of the first large-scale adoption study of major depression.

The study, “Sources of Parent-Offspring Resemblance for Major Depression in a National Swedish Extended Adoption Study,” published Dec. 13 in JAMA Psychiatry, a monthly, peer-reviewed medical journal ...

Featured Faculty: Judy Silberg, Ph.D.

Dr. Judy Silberg, Ph.D. is an Associate Professor in the Department of Human and Molecular Genetics. A fortuitous meeting with Drs. Lindon Eaves, D.Sc., Nick Martin, and Andrew Heath while working on her PhD in Clinical Psychology at Virginia Commonwealth University led to her life-long involvement in the field of behavior genetics. Her initial research interest began with the influence of genetic and environmental factors on pre- and peri-menstrual disorders using ...

Featured Student: Kristin Mignogna

Kristin Mignogna is a PhD student in the Psychiatric, Behavioral, and Statistical Genetics (PBSG) program. Her interests in psychiatric genetics began as an undergraduate at the University of Virginia, where she majored in biology and psychology. Although she was initially interested in physiology and anatomy, she discovered that she was actually more passionate about genetics during an introductory biology course. Therefore, upon graduation, she was searching for graduate programs that integrated both genetics and psychology, and ...
