The 5-HTTLPR polymorphism and eating disorders: A meta-analysis

Abstract

OBJECTIVE: Eating disorders are influenced by both environmental factors and genes. The 5-HTTLPR polymorphism of serotonin transporter gene has been suggested as a good candidate. This meta-analysis was undertaken: (1) to investigate the association between 5-HTTLPR and eating disorders considered as a whole, including anorexia (AN), bulimia (BN), and binge eating disorder (BED); (2) to extend recently reported findings on the association between 5-HTTLPR and AN-BN. METHOD: PubMed, ISI, and PsycINFO databases were searched for studies published until October 2009. Fifteen studies have been included. Data were analyzed with the Cochrane Collaboration Review Manager Software. Quality of studies and publication bias were assessed. RESULTS: An association between S allele and eating disorders, in particular AN, has been found. DISCUSSION: To be carrier of the 5-HTTLPR S allele seem to represent a risk factor for eating disorders, especially for AN. However, considering the reported high between-study heterogeneity, future studies should focus on more homogeneous endophenotype.

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.
