  • Beschreibung: The aim of the investigation was to test genes for predisposition to bipolar affective disorder. Therefore, we studied candidate genes in a sample of unrelated patients (n = 102) and healthy controls (n = 79) of Austrian origin, searching for a possible association between polymorphic DNA markers of 5 candidate genes (serotonin transporter,<i> 5-HTT;</i> serotonin 2a receptor, <i>5-HT2a;</i> dopamine D2 receptor, <i>DRD2; </i>dopamine D3 receptor, <i>DRD3;</i> dopamine transporter, <i>DAT1</i>) and bipolar disorder. There was an association between allelic and genotypic frequencies of <i>5-HTT</i> and affection status (p = 0.014 and p = 0.017, respectively). However, after correction for multiple comparisons (Bonferroni), these results did not remain significant. Nevertheless, the findings might suggest that alterations in the structure of <i>5-HTT</i> are involved in the pathogenesis of bipolar disorder, which could have major implications in treatment. No association between <i>5-HT2a, DRD2, DRD3, DAT1</i> and bipolar disorder was found.
