Epigenetics at the Interface of Genes and the Environment: ACEs, Critical Risk Periods and the Identification of Biomarkers for Mental Illnesses
Mental illnesses are thought to result from the combined influence of genes and environment. While studies have identified critical risk periods for the development of mental illnesses, the biological bases for these diseases have remained elusive until recently. The field of epigenetics seeks to identify the biological markers that reflect the interaction of a persons genes and the environments they experience.
- Discuss the evidence for these biological markers that can be influenced by environmental exposures such as ACEs.
- Discuss the discovery of epigenetic biomarkers capable of predicting risk to future mental illnesses.
Zachary A. Kaminsky, PhD
Assistant Professor/Johns Hopkins University, School of Medicine/Department of Psychiatry
Dr. Kaminsky trained in one of the first labs studying epigenetics in psychiatry. He had investigated epigenetic influences on suicide, post partum depression and PTSD where he generated some of the first and most widely replicating epigenetic biomarkers in psychiatry. He is working on the development of disease predictive biomarkers. Dr. Kaminsky attempts to better understand the molecular epigenetic underpinnings of psychiatric conditions to enable the generation of “bench to bedside” translational findings.
