Gene×environment interactions at the serotonin transporter locus

Abstract

Background Although it is universally accepted that human disease and behavior depend upon both environmental and genetic variation, a view supported by family and twin studies, examples of environmental interactions with genes identified at the molecular level (G x E) are not so well established. Methods We carried out a systematic review and meta-analysis of the serotonin transporter (5-HTTLPR) polymorphic region x stressful life event (SLE) literature and investigated to what extent the main effects reported in this literature are consistent with a number of G x E hypotheses. Our aim was to provide a framework in which to assess the robustness of the claim for the presence of an interaction. Results The results from our systematic review and meta-analysis indicate that the main effect of 5-HTTLPR genotype and the interaction effect between 5-HTTLPR and SLE on risk of depression are negligible. We found that only a minority of studies report a replication that is qualitatively comparable to that in the original report. Conclusions Given reasonable assumptions regarding likely genetic and environmental effect sizes, our simulations indicate that published studies are underpowered. This, together with other aspects of the literature, leads us to suggest that the positive results for the 5-HTTLPR x SLE interactions in logistic regression models are compatible with chance findings.

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.
