Abstract: | We selected 42 patients with bipolar disorder type I (BPI) and 40 healthy controls for genetic analysis of DNA polymorphisms in the serotonin receptor 2c (5-HTR2c) and serotonin transporter (5-HTT) genes. No significant associations were found in the total patient sample. However, when the individuals were divided according to gender, trends for association with both polymorphisms (P = 0.051 for 5-HTR2c and P = 0.049 for 5-HTT) in female patients were observed. These results suggest that variations in these genes may be responsible for a minor increase in susceptibility for bipolar disorder in women. |
