DOIAbstract
DNA methylation variation at HP / BP3 and TTC9B is modified by estrogen exposure in the rodent hippocampus and was previously shown to be prospectively predictive of postpartum depression (PPD) when modeled in antenatal blood. The objective of this study was to replicate the predictive efficacy of the previously established model in women with and without a previous psychiatric diagnosis and to understand the effects of changing hormone levels on PPD biomarker loci. Using a statistical model trained on DNA methylation data from N = 51 high-risk women, we prospectively predicted PPD status in an independent N = 51 women using first trimester antenatal gene expression levels of HP I BP3 and TTC9B, with an area under the receiver operator char...
