Association analysis of the polymorphisms of dopamine-β-hydroxylase and norepinephrine transporter genes with panic disorder / 中华行为医学与脑科学杂志

ABSTRACT

Objective:To explore the association between dopamine-β-hydroxylase (DβH), norepinephrine transporter (NET) gene polymorphisms and panic disorder(PD).Methods:The structured clinical interview for the diagnostic and statistical manual of mental disorders fourth edition (DSM-Ⅳ) axis Ⅰ disorders was administered by trained clinical psychiatrist, 139 patients with PD(PD group) and 196 healthy controls(control group) were enrolled in the study.Single nucleotide polymorphism(SNP) genotyping was performed using an improved multiplex ligation detection reaction technique.SPSS 16.0 and PLINK softwares were used to compare the allele frequency and genotype distribution.Results:(1)Compared with control group, PD group carried more G allele(76.3% vs 68.4%) and fewer A allele(23.7% vs 31.6%) in NET rs5569, and the difference was significant(χ 2=4.986, OR=0.67, 95% CI 0.47-0.95, P<0.05). However, the correlation was no longer significant after adjusting for Bonferroni’s multiple testing( P>0.05). (2)The additive model of NET rs5569 showed a association with PD ( OR=0.68, 95% CI 0.48-0.96, P<0.05). And the recessive model of DβH rs1611114 showed a association with PD( OR=0.42, 95% CI 0.18-0.96, P<0.05). However, these correlations were no longer significant after adjusting for Bonferroni's multiple testing( P>0.05). (3)No matter allele or genotype, there were no significant differences in DβH (rs129882, rs1611114, rs1611115) and NET (rs2242446, rs28386840) gene polymorphisms between panic disorder group and control group(all P>0.05). Conclusion:The present study indicates that there is no significant association of DβH and NET gene polymorphisms with PD.
