The 5HTTLPR polymorphism, psychopathologic symptoms, and platelet [<sup>3</sup>H-] paroxetine binding in bulimic syndromes
Bibliographic record
Abstract
BACKGROUND: A short (s) allele in the promoter region of the 5-hydroxytryptamine (5-HT) transporter gene (5HTTLPR) has been associated with low transcription of the 5-HT transporter protein, and with clinical manifestations including impulsivity, affective disorder, and bulimia nervosa. METHODS: We studied implications of the 5HTTLPR s allele for eating symptoms, psychopathologic traits, and platelet [3H-] paroxetine binding in 59 women with bulimia spectrum syndromes. RESULTS: Compared with those without it, carriers of the s allele of 5HTTLPR showed significantly more affective instability, behavioral impulsivity, interpersonal insecurity, comorbid borderline personality disorder (BPD), and lower density (Bmax) of paroxetine-binding sites. CONCLUSIONS: Our results suggest that proneness to impulsivity, affective dysregulation, and reduced central 5-HT reuptake may (in part) be codetermined by the 5HTTLPR polymorphism. However, given inconsistent 5HTTLPR expression in different populations, we speculate that we may be observing a phenotype (i.e., eating disorder)-dependent manifestation.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
