Family-Based Association Test of the 5HTTLPR and Aggressive Behavior in a General Population Sample of Children
Abstract
Background A promoter polymorphism in the serotonin transporter (5HTTLPR) has functional effects on an important physiologic process involved in serotonin (5HT) signaling. Despite the fact that variation in the 5HT system has long been implicated in the etiology of aggressive behaviors, only a few association-based studies with mixed results have been reported.Methods We conducted family-based tests of association in a sample of 366 families from which 1187 genotypes of the 5HTTLPR were generated using polymerase chain reaction. Ratings of aggressive behavior were obtained from parents and teachers longitudinally using the Child Behavior Checklist (CBCL) and Teacher Report Form (TRF), instruments widely used in behavioral and psychiatric genetics.Results Within-family tests suggest an association between the s-allele of the 5HTTLPR and higher aggressive behavior in middle childhood. The strongest association was at age 9 and for an aggregate measure of teacher-rated aggressive behavior.Conclusions This is the first report of an association analysis of the 5HTTLPR in a general population sample of school-age children. The results provide some support for the hypothesis that the functional effects of the 5HTTLPR s-allele are associated with higher levels of aggressive behavior in middle childhood.

The S-allele was significantly associated with teacher reported aggressive behaviors at age 9 for both boys and girls.
“Similarly, the S-allele was significantly associated with teacher reported aggressive behaviors at age 9 for both boys and girls [87] and with increased aggressive behaviors and hostility in a group of female Caucasian Russian swimmers [88].”

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.
