Methylation Matters: Interaction Between Methylation Density and Serotonin Transporter Genotype Predicts Unresolved Loss or Trauma
Open accessAbstract
Background Do genetic or epigenetic factors play a role in making some individuals more vulnerable than others to loss of attachment figures or other traumatic experiences?Methods DNA was obtained from growth phase entrained Epstein-Barr Virus (EBV) transformed lymphoblast cell lines from 143 adopted participants. Genotype of the serotonin transporter linked polymorphic region (5HTTLPR) was determined, and methylation ratios for each of the C-phosphate-G (CpG) residues were assessed using quantitative mass spectroscopy. Unresolved loss or trauma was established using the Berkeley Adult Attachment Interview.Results Higher levels of methylation of the 5HTT promoter associated CpG island were associated with increased risk of unresolved responses to loss or other trauma in carriers of the usually protective 5HTTLPR//variant. The ss variant of 5HTTLPR predicted more unresolved loss or trauma, but only in case of lower levels of methylation. Higher levels of methylation of the ss variant were associated with less unresolved loss or other trauma.Conclusions Associations between 5HTTLPR polymorphisms and psychological problems are significantly altered by environmentally induced methylation patterns. Methylation may serve as the interface between adverse environment and the developing organism.

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.
