Genome-wide association analyses identify 95 risk loci and provide insights into the neurobiology of post-traumatic stress disorder
NEW YORK, April 18, 2024 /PRNewswire/ -- The Global PTSD Genetics initiative founded in 2015 by Cohen Veterans Bioscience, the Stanley Center for Psychiatric Research at Broad Institute, and the Psychiatric Genomics Consortium today announces a pivotal milestone in the genetics of post-traumatic stress disorder (PTSD) has been achieved and published in Nature Genetics on April 18,2024.
- Convergent multiomic approaches identified 43 potential causal genes, including modulators of neurotransmitters, ion channels, axon guidance, and synapses.
- Additional top genes influence stress, immune, fear, and threat-related processes, previously hypothesized to underlie PTSD neurobiology.
- These findings strengthen the understanding of neurobiological systems relevant to PTSD pathophysiology, while also opening new areas for investigation.
- Posttraumatic stress disorder (PTSD) is characterized by intrusive thoughts, hyperarousal, avoidance, and negative alterations in cognition and mood that can become persistent for some individuals after traumatic event exposure.
