Abstract

OBJECTIVE: In the present investigation we screened a large number of single nucleotide polymorphisms in the genes relevant to the neurobiology of anxiety for their association with panic disorder (PD). METHODS: The study sample included 127 patients with PD and 146 healthy control subjects. Using Arrayed Primer Extension technology we genotyped 90 polymorphisms in 21 candidate genes of serotonin, cholecystokinin, dopamine and opioid neurotransmitter systems. The association and haplotype analyses were performed in the whole group (PD-all) and in the subgroups of PD comorbid with major depression (PD-comorbid, n = 60) and without any comorbidity (PD-pure, n = 42). RESULTS: From the set of 90 polymorphisms, eight single nucleotide polymorphism markers in eight genes displayed at least a nominal association with any of the studied PD phenotype subgroups. Several polymorphisms of cholecystokinin, serotonin and dopamine systems were associated with PD-all and/or PD-comorbid phenotypes, while pure PD was associated only with HTR2A receptor 102T-C (P = 0.01) and DRD1 receptor -94G-A (P = 0.02) polymorphisms. Haplotype analysis supported an association of the cholecystokinin gene TG haplotype with the PD-all group (P = 0.04), whereas DRD1 receptor CAA and HTR2A receptor AT haplotypes were associated with a lower risk for PD-pure phenotype (P = 0.03 and P = 0.04, respectively). CONCLUSIONS: The study results suggest that genetic variants of several candidate genes of neurotransmitter systems, each of a minor individual effect, may contribute to the susceptibility to PD. Our data also indicate that genetic variability may have a distinctive influence on pure and comorbid phenotypes of PD.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
