Genomic Perspectives on PTSD (PDF)

RQ Vol. 35(2), 2024 by Matthew J. Girgenti, PhD

Editorial Director: Paul Holtzheimer, MD
Bibliographic Editor: David Kruidenier, MLS
Managing Editor: Heather Smith, BA Ed


Abstract: PTSD has a heritability of 20%-40% meaning that a significant portion of the risk of developing PTSD after a trauma is related to a person's genes and how these are expressed. In this Research Quarterly, Dr. Matthew Girgenti provides a concise summary of the genomics related to PTSD, emphasizing how this can help better understand the biology of the disorder. This includes discussion of the work ongoing in the National Center's PTSD Brain Bank.
