Objective:
The objective of this study was to investigate whether the functional rs25531 promoter polymorphism in the serotonin transporter gene is associated with premenstrual dysphoric disorder.
Study Design:
The study sample comprised 53 women with clinically diagnosed premenstrual dysphoric disorder (age range, 27-46 years; mean, 37.7 years) and 52 healthy control subjects (age range, 22-48 years; mean, 36.2 years). The rs25531 polymorphism was genotyped in both groups. Because of its close proximity to rs25531, the 5-HTTLPR promoter polymorphism was also genotyped. Genotype and allele frequencies for rs25531 and for the composite 5-HTTLPR/rs25531 marker were analyzed by chi(2) test.
Results:
There was no significant association between any genotype and clinical category and no significant allele distribution profiles for rs25531 or 5-HTTLPR/rs25531 in either the premenstrual dysphoric disorder or the control groups.
Conclusion:
These findings do not support a major role for rs25531, either in isolation or combined with 5-HTTLPR, in contributing to susceptibility to premenstrual dysphoria.
