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 ...

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 ...

The 2021 VIPBG Excellence Awards Announced

The Virginia Institute for Psychiatric and Behavioral Genetics pre- and post-doc awards were announced on December 16, 2021. Annually since 2007, one predoctoral and one postdoctoral trainee are selected to receive the awards. The process requires VIPBG faculty members to first nominate exceptional trainees. The final recipients are selected after a faculty discussion and vote. These awards consist of a certificate of recognition in addition to a $500.00 gift.

This year, the awardees include Terrell Hicks, ...

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 ...
