“Holy cow, where do I sign up?” Attitudes of Military Veterans toward Epigenomic Biomarker Toxic Exposure Testing

Background With the signing of the PACT Act in 2022, there is great interest and investment in studying toxic exposures encountered during military service. One way to address this is through the identification of epigenomic biomarkers associated with exposures. There is increasing evidence suggesting that exposure to toxic substances may result in alterations to DNA methylation and resultant gene expression. These epigenomic changes may lead to adverse health effects for exposed individuals and their offspring. While the development of epigenomic biomarkers for exposures could facilitate understanding of these exposure-related health effects, such testing could also provide unwanted information.
