Evaluating the role of common risk variation in the recurrence risk of schizophrenia in multiplex schizophrenia families

Evaluating the role of common risk variation in the recurrence risk of schizophrenia in multiplex schizophrenia families

Schizophrenia (SCZ) is a severe, clinically heterogeneous psychiatric disorder with a population prevalence of ~1% [1]. Twin, family, and adoption studies consistently show a strong genetic component, with heritability estimates of around 0.75–0.80 [2,3,4,5,6], and family history (FH) remains the strongest risk factor for developing SCZ [7]. Despite high heritability, ~2/3 of SCZ cases report no FH of psychotic illness, and most subjects with a positive FH (FH+) report only a single affected relative [8, 9], concordant with the rates ...

Genome-wide analysis of schizophrenia and multiple sclerosis identifies shared genomic loci with mixed direction of effects

Genome-wide analysis of schizophrenia and multiple sclerosis identifies shared genomic loci with mixed direction of effects

In the last decade, genome-wide association studies (GWAS) have identified a large number of common genetic risk variants associated with complex human phenotypes (Visscher et al., 2017). Many genetic variants identified by GWAS exhibit varying degrees of genetic pleiotropy (Solovieff et al., 2013), and investigating the nature of these shared genetic risks is important for improving our understanding of the etiology and underlying genetic architecture of complex human disorders. A widely used method for assessing the genetic relationship between two ...

Genome Comparisons Reveal DNA Risk Variants Differ in People of East Asian vs. European Ancestry

Genome Comparisons Reveal DNA Risk Variants Differ in People of East Asian vs. European Ancestry

An analysis of multiple genome-wide studies making associations between depression and “risk” locations in the human genome has provided a vivid demonstration that results can vary substantially depending on the ethnicity and even country of origin of those whose genomes are being studied.

Members of the major depression working group of the Psychiatric Genomics Consortium and an international team of researchers that included 10 recipients of BBRF grants and prizes and two BBRF Scientific Council members, Kenneth S. Kendler, M.D., and ...

Dr. Roberson-Nay Receives $275K NIMH R21 Funded Research Grant

Dr. Roberson-Nay Receives $275K NIMH R21 Funded Research Grant

Roxann Roberson-Nay, Ph.D. received a two year, $275K NIMH R21 grant for her “Quantification and Characterization of Bulk and L1CAM-Enriched Exosomal MicroRNA Cargo in Healthy Young People” research study.

Extracellular vesicles (EVs) are membrane-bound sacs that transport bioactive materials like proteins, DNA, and RNA. EVs are released from all (or nearly all) tissues into the bloodstream as a normal part of physiology. Because EVs easily cross the blood-brain-barrier, analyzing cell surface markers and biological cargo may enable researchers to ...

World’s largest study of genetic risk factors for depression will enroll 20,000 women

World’s largest study of genetic risk factors for depression will enroll 20,000 women

The five-year study involving VCU’s Virginia Institute for Psychiatric and Behavioral Genetics aims to better understand major depressive disorder and diversity of genetic data.

team of researchers will lead the largest population study of its kind aimed at learning more about the genetic variations that affect individuals’ risk for depression after receiving a five-year, $8.98 million grant from the National Institute of Mental Health, part of the National Institutes of Health.

The study, “Identifying the Genetic Causes of Depression in a Deeply ...

Cracking the code for resilience

Cracking the code for resilience

A VCU School of Medicine researcher is exploring the genetic underpinnings of trauma responses in the hope of improving mental health care.

Given current events ranging from the ongoing pandemic to giant wildfires and powerful hurricanes, it’s not surprising that many people find their emotional reserves are depleted. Statistics from the Kaiser Family Foundation show that about 4 in 10 adults in the U.S. have reported symptoms of anxiety or depressive disorder during the COVID-19 pandemic, up from 1 in 10 ...

How virtual reality may help explore the role of fear in youth at risk for violence and crime

How virtual reality may help explore the role of fear in youth at risk for violence and crime

A VCU professor has received a $2.5 million grant from the National Institute of Mental Health to study conduct disorder and callous-unemotional traits using VR technology.

Conduct disorder — often characterized by aggression, theft, vandalism, violations of rules and lying — is one of the most prevalent and debilitating psychiatric disorders that emerges during childhood and adolescence.

There is a subgroup of those with conduct disorder who are more likely to engage in chronic violence and criminal behavior. These individuals display severe ...

Network Psychometrics Workshop – June 18-20, 2019

Network Psychometrics Workshop – June 18-20, 2019

The workshop starts with a conceptual introduction on why items in psychological data tend to co-occur, and what this implies about the constructs such as mental disorders, cognitive abilities, personality, and attitudes. This is followed by an introduction to social and psychological network models; an overview of the network literature in psychopathology (the field where network psychometric models have been used most over the last years); and a summary of important topics (centrality, comorbidity, early warning signals).
