Association of serotonin transporter regulatory region polymorphism and abnormal eating behaviors

Association of 5‐HTT gene polymorphism, platelet MAO activity, and drive for thinness in a population‐based sample of adolescent girls

“…The study on a nonclinical Japanese population found the l/l genotype to be more frequent among participants with abnormal eating attitudes and behavior. 37 Since there are differences in genotype frequencies between Caucasian and Asian populations, the latter possessing the l/l genotype less frequently, 38 these results are not directly comparable with the present ones. However, recently Monteleone et al reported that both the l/l genotype and the presence of the l-allele of the 5-HTTLPR to be more frequent in Caucasian women with binge-eating disorder.…”

Association between serotonin transporter gene polymorphism and eating disorders: A meta‐analytic study

“…25,27 The paper by Lauzurica et al had provided genetic data of a subset of patients who had history of AN episode; therefore, these patients were categorized as both AN and BN groups. 31 Two studies were excluded because they had examined abnormal eating behaviors in nonclinical samples, 34 or binge ED, 35 not in patients with AN or BN. A few studies examining the association between EDs and 5-HTTLPR were excluded because they were not in case-control design.…”

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

“…Of these 24 articles, two were excluded because were reviews, 9,10 one was excluded because was performed on nonclinical samples, 15 five were excluded because were performed on overlapping samples [16][17][18][19][20] and one was excluded because no 5-HTTLPR genotypic frequencies were given for patients 21 (see Fig. 1 for the flow diagram).…”
