Objectives: To determine the degree of association of five single nucleotide polymorphisms at the 5′-untranslated region (5′-UTR) of the human dopamine transporter gene (hSLC6A3; hDAT1) in bipolar affective disorder.
Methods: In a case–control design study, the polymorphisms were genotyped for allelic and genotypic distribution between 105 index cases (50 males) with bipolar affective disorder according to DSM IV and 199 unaffected control subjects (120 males).
Results: At the 5′-UTR locus of hSLC6A3, no significant allelic or genotypic differences were observed between index cases and controls. However, distinct 5-locus genotypes accumulated in subjects with bipolar affective disorder compared to control subjects (p = 0.029, odds ratio 1.84, 95% confidence interval 1.12–3.02).
Conclusions: In conclusion, our data do not provide evidence for a major role of the 5′-UTR of the dopamine transporter gene in bipolar affective disorder. A minor contribution of distinct genotypes may be possible and warrants replication in extended samples.
