    The risk of posttraumatic stress disorder (PTSD) following trauma is heritable, but robust common variants have yet to be identified. In a multi-ethnic cohort including over 30,000 PTSD cases and 170,000 controls we conduct a genome-wide association study of PTSD. We demonstrate SNP-based heritability estimates of 5-20%, varying by sex. Three genome-wide significant loci are identified, 2 in European and 1 in African-ancestry analyses. Analyses stratified by sex implicate 3 additional loci in men. Along with other novel genes and non-coding RNAs, a Parkinson's disease gene involved in dopamine regulation, PARK2, is associated with PTSD. Finally, we demonstrate that polygenic risk for PTSD is significantly predictive of re-experiencing symptoms in the Million Veteran Program dataset, although specific loci did not replicate. These results demonstrate the role of genetic variation in the biology of risk for PTSD and highlight the necessity of conducting sex-stratified analyses and expanding GWAS beyond European ancestry populations.

    Risk of spontaneous preterm birth in relation to maternal depressive, anxiety, and stress symptoms.
    (The Journal of reproductive medicine, 2013-01) Sanchez, Sixto E; Puente, Gabriella C; Atencio, Guillermo; Qiu, Chungfang; Yanez, David; Gelaye, Bizu; Williams, Michelle A

    Objective

    To examine the risk of preterm birth (PTB) in relation to maternal psychiatric symptoms during pregnancy in Peruvian women.

    Study design

    This case-control study included 479 PTB cases and 480 term controls. In-person interviews were conducted to assess women's depressive, anxiety, and stress symptoms using the Patient Health Questionnaire (PHQ-9) and the Depression Anxiety Stress Scales (DASS-21). Multivariable logistic regression procedures were used to estimate adjusted odds ratios (aORs) and 95% confidence intervals (CIs).

    Results

    Compared with women reporting no or minimal depressive symptoms, the aOR (95% CI) for PTB associated with consecutive severity of depressive symptoms based on the PHQ-9 assessment method were as follows: mild, 2.22 (95% CI 1.64-3.00) and moderate-severe, 3.67 (95% CI 2.09-6.46). The corresponding aORs for normal, mild, and moderate-severe depressive symptoms based on the DASS-21 assessment were 1.00 (reference), 3.82 (95% CI 1.90-7.66), and 2.90 (95% CI 1.66-5.04), respectively. A positive gradient was observed for the odds of PTB with severity of anxiety (Ptrend < 0.001) and stress symptoms (Ptrend < 0.001).

    Conclusion

    The odds of PTB increased in pregnant Peruvian women with psychiatric symptoms. Efforts to screen and treat affected women may modify risks of PTB and possibly other associated disorders.
