Objective To explore the association of serotonin transporter gene-linked polymorphic region (5-HTTLPR) gene polymorphisms with bipolar disorder and affective temperaments. Methods Case-control design was adopted, and 305 patients with bipolar disorder and 272 normal controls were enrolled. Temperament Evaluation of Memphis, Pisa, Paris and San Diego-autoquestionnaire version (TEMPS-A) was employed to assess the affective temperaments. Chi-square test, T test, nonparametric test and ANOVA were used to explore the association of 5-HTTLPR gene polymorphisms with bipolar disorder and affective temperaments. Results 5-HTTLPR L/S polymorphisms were associated with bipolar disorder in females (genotype, χ2=6.769, P=0.034;allele, χ2=6.028, P=0.014), S allele of 5-HTTLPR L/S polymorphisms was associated with anxious temperament of patients with bipolar disorder (t=8.248,P=0.005), and LA allele of 5-HTTLPR rs25531 A/G polymorphisms was associated with hyperthymic temperament of patients with bipolar disorder (Z=-2.205,P=0.027). Conclusion 5-HTTLPR gene polymorphisms are associated with the prevalence of bipolar disorder in females, which can also regulate the affective temperaments of patients with bipolar disorder in some degree.
