Current developments and controversies: does the serotonin transporter gene-linked polymorphic region (5-httlpr) modulate the association between stress and depression?

Abstract

PURPOSE OF REVIEW: Human observational studies have shown that, in interaction with life stress, the short or S-allele of the serotonin transporter gene-linked polymorphic region (5-HTTLPR) is associated with an enhanced risk for depression. However, this gene-by-environment interaction (G×E) has recently been questioned by two meta-analyses. We aim to provide an overview and appraisal of recent developments and controversies. RECENT FINDINGS: The statistical approach of the meta-analyses aimed at a very strict replication of the initial finding and, accordingly, included only a minority of all available studies. Furthermore, the negative results of the meta-analyses appear to be predominantly driven by a few large studies that used retrospective, self-report measures of life stress. In contrast, among 19 studies using interview-based or more objective measures of stress, there were 13 replications, five part-replications and only one nonreplication. Finally, a broader approach based on evidence from different research fields and methodologies supports a 5-HTTLPR by stress interaction. SUMMARY: Whereas there is no doubt that the meta-analyses are methodologically sound, it appears that this technique is only in part suitable for appraising all of the available evidence. Furthermore, convergent evidence is accumulating from different research fields that 5-HTTLPR is indeed closely associated with different biological pathways associated with stress regulation and depression.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • A genetic polymorphism that downregulates the serotonin reuptake transporter predisposes towards depression and other related mood disorders.

    “On the other hand, a genetic polymorphism that downregulates the very same serotonin reuptake transporter, thus acting in the same direction as the drugs, has the opposite effect on mood, predisposing towards depression and other related mood disorders ([30]; though see also [31] for a discussion of replication failures).”

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.
