Norepinephrine transporter gene (NET) variants in patients with panic disorder.
Several lines of evidence suggest that catecholamines, especially norepinephrine, are implicated in the etiology and/or symptomatology of panic disorder (PD). At the cellular level, functional noradrenergic neurotransmission depends on synaptic reuptake of norepinephrine as mediated by the norepinephrine transporter (NET). A pharmacological target of agents with an established anti-panic efficacy, e.g. tricyclic antidepressants, the NET is of particular interest in PD. We investigated the NET gene for the presence of 6 naturally occurring exonic sequence variants, 5 of which give rise to amino acid substitutions (Val69Ile, Thr99Ile, Val245Ile, Val449Ile and Gly478Ser) in a population of 87 patients with PD and 89 healthy controls. Except for a silent substitution (G1287A), overall frequencies of variant alleles were low (< or =0.016). None of the variants under study was found to be associated with PD regardless of an additional diagnosis of agoraphobia.
