Genomic predictors of combat stress vulnerability and resilience in U.S. Marines: A genome-wide association study across multiple ancestries implicates PRTFDC1 as a potential PTSD gene. - Psychoneuroendocrinology (2015) · Nievergelt CM, Maihofer AX, Mustapic M, Yurgil KA, Schork NJ, Miller MW, Logue MW, Geyer MA, Risbrough VB, O'Connor DT, Baker DG · PubMed 25456346
Research on the etiology of post-traumatic stress disorder (PTSD) has rapidly matured, moving from candidate gene studies to interrogation of the entire human genome in genome-wide association studies (GWAS). Here we present the results of a GWAS performed on samples from combat-exposed U.S. Marines and Sailors from the Marine Resiliency Study (MRS) scheduled for deployment to Iraq and/or Afghanistan. The MRS is a large, prospective study with longitudinal follow-up designed to identify risk and resiliency factors for combat-induced stress-related symptoms. Previously implicated PTSD risk loci from the literature and polygenic risk scores across psychiatric disorders were also evaluated in the MRS cohort. Participants (N=3494) were assessed using the Clinician-Administered PTSD Scale and d

Lifestyle context
Concrete actions anchored to the cited research. We do not prescribe, we describe.
Exercise
-
Regular aerobic exercise for PTSD symptom reduction Moderate
Exercise is evidence-based intervention for PTSD; genetic risk warrants proactive engagement in physical activity for symptom prevention
150 minutes moderate-to-vigorous aerobic exercise weekly, distributed across 3-5 days
Lifestyle
-
Daily mindfulness or stress management practice Moderate
Mindfulness reduces hyperarousal and hypervigilance core to PTSD; genetic susceptibility warrants systematic stress-management skill development
10-20 minutes daily mindfulness meditation or equivalent structured stress management
-
Sleep hygiene optimization for PTSD prevention Moderate
Sleep disturbance is core symptom and relapse trigger in PTSD; systematic sleep optimization may reduce symptom burden in genetically susceptible individuals
Maintain consistent sleep schedule; target 7-9 hours nightly; address sleep disorders promptly
Screening
-
PTSD risk screening with mental health professional Moderate
rs10457838 in UST shows significant genetic association with post-traumatic stress disorder risk in well-powered GWAS (n=3494)
Schedule baseline PTSD screening assessment; discuss risk factors and preventive strategies
