Abstract The pathophysiological mechanisms underlying binge eating disorder (BED) are poorly understood. There is evidence that abnormalities in brain serotonin (5HT) play an important role in binge eating behavior, therefore genes involved in 5HT transmission, such as the 5HT transporter (5HTT) gene, may contribute to the biological vulnerability to BED. We examined whether the polymorphism of the promoter of the 5HTT gene, consisting of a long (L) and a short (S) variant, was associated with BED. Seventy-seven obese or non-obese women with BED, and 61 normal weight control women were genotyped at the 5HTT gene linked polymorphism (5HTTLPR). Statistical analysis showed that both the LL genotype and the L allele of the 5HTTLPR were significantly more frequent in BED subjects. Moreover, the L allele was associated with a moderate but significant risk to develop BED (OR = 2.01, CI = 1.33-3.57). Although these data should be regarded as preliminary because of the small size of our sample, they suggest that the 5HTTPRL may contribute to the genetic susceptibility to BED.
