Abstract

The early-life social environment can induce stable changes that influence neurodevelopment and mental health. Research focused on early-life adversity revealed that early-life experiences have a persistent impact on gene expression and behavior through epigenetic mechanisms. The hypothalamus-pituitary-adrenal axis is sensitive to changes in the early-life environment that associate with DNA methylation of a neuron-specific exon 17 promoter of the glucocorticoid receptor (GR) (Nr3c1). Since initial findings were published in 2004, numerous reports have investigated GR gene methylation in relationship to early-life experience, parental stress, and psychopathology. We conducted a systematic review of this growing literature, which identified 40 articles (13 animal and 27 human studies) published since 2004. The majority of these examined the GR exon variant 1F in humans or the GR17 in rats, and 89% of human studies and 70% of animal studies of early-life adversity reported increased methylation at this exon variant. All the studies investigating exon 1F/17 methylation in conditions of parental stress (one animal study and seven human studies) also reported increased methylation. Studies examining psychosocial stress and psychopathology had less consistent results, with 67% of animal studies reporting increased exon 17 methylation and 17% of human studies reporting increased exon 1F methylation. We found great consistency among studies investigating early-life adversity and the effect of parental stress, even if the precise phenotype and measures of social environment adversity varied among studies. These results are encouraging and warrant further investigation to better understand correlates and characteristics of these associations.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • ELS is associated with hypermethylation of NR3C1 in exon 1F, which is associated with downregulation of GR in brain and periphery.

    “In the case of NR3C1, ELS is associated with hypermethylation particularly in exon 1F, which in turn is associated with downregulation of GR in the brain and periphery [80,81].”

    From Trauma, PTSD, and the Developing Brain (2017) · cites this paper as [80]

    The Results (Early-life adversity; page unavailable) report increased exon 1F methylation in 9 of 10 human studies of early-life adversity. The Introduction reports decreased GR1F expression in the hippocampus of suicide completers with childhood abuse histories. The Conclusion reports exon 1F methylation in peripheral cells but says its effect on GR expression there is likely, rather than establishing peripheral GR downregulation. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Hypermethylation of NR3C1 in individuals exposed to childhood adversity correlates with increased vulnerability to PTSD, depression, and suicide risk.

    “hypermethylation of NR3C1 in individuals exposed to childhood adversity correlates with increased vulnerability to PTSD, depression, and suicide risk”

    From The clinical use of epigenetics in psychiatry: a narrative review of epigenetic mechanisms, key candidate genes, and precision psychiatry (2025) · cites this paper as [2]

    The Introduction and Conclusion report increased NR3C1 exon 1F methylation after childhood adversity, including in suicide completers with a history of abuse, and describe adversity-related vulnerability to depression or other mood disorders. They do not establish that hypermethylation predicts increased risk of all three outcomes. The Results (Psychological stress/Psychopathology) instead report mixed methylation findings across psychiatric conditions, including decreased exon 1F methylation in a PTSD study. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Klengel et al. and other investigators focusing on early childhood trauma effects and gene-by-early-life-environment interactions on methylation did not assess the contribution of parental experiences, particularly trauma exposure.

    “Klengel et al. (38) and other investigators (51,52) focusing on early childhood trauma effects and the influence of the gene 3 early life environment interactions on methylation did not assess the contribution of parental experiences, particularly trauma exposure.”

    From Holocaust Exposure Induced Intergenerational Effects on FKBP5 Methylation (2016) · cites this paper as [51]

    The Conclusion describes Klengel et al.’s finding on childhood maltreatment, FKBP5 genotype and methylation. The Results discuss parental stress in a separate group of studies, but do not establish that Klengel et al. or the other investigators named in the citing sentence failed to assess parental trauma exposure. (LLM, conf=0.78)

    Experimental — accuracy not yet measured
  • Studies across animals and humans point to altered methylation and expression of GR (NR3C1) and FKBP5 following ELS.

    “Studies across animals and humans point to altered methylation and expression of the glucocorticoid receptor (GR or NR3C1) and FKBP5, a GR chaperone protein which impedes GR signaling, following ELS [79–81].”

    From Trauma, PTSD, and the Developing Brain (2017) · cites this paper as [80]

  • Other tissues such as cord blood, peripheral blood, buccal epithelial cells and placental tissues showed similar results regarding enhanced methylation of NR3C1 in association with early life adversity.

    “Other tissues, such as cord blood, peripheral blood, buccal epithelial cells and placental tissues were also tested, and the majority of them showed similar results in regard to enhanced methylation of NR3C1 in association with early life adversity (138, 144).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
