There is strong evidence for a genetic contribution to the pathogenesis of panic disorder, with the functional catechol‐O‐methyltransferase (COMT) val158met polymorphism having been suggested as a potential susceptibility factor. In the present study, a meta‐analysis of six available case‐control studies (557 patients with panic disorder and 763 healthy controls in total) on the role of the COMT val158met polymorphism in panic disorder was conducted in an attempt to reconcile previous conflicting results and to facilitate evaluation of the role of COMT gene variation in panic disorder. Overall, no significant association, but strong between‐study heterogeneity, was discerned. Analysis of studies pooled by ancestry yielded a significant association of the COMT 158val allele with panic disorder in Caucasian samples and, conversely, a trend towards association of the COMT 158met allele with the disorder in Asian samples. Interestingly, stratification for gender as well as ethnicity revealed that association of the 158val allele in Caucasians and, reciprocally, the 158met allele in Asian samples was restricted to females. The present meta‐analysis provides tentative support for the COMT val158met polymorphism as a possible risk factor for panic disorder, with differential effects in Caucasian and Asian populations, and suggests a female‐specific effect. However, given the relatively small number of case‐control studies presently available, several more association studies, preferably including a larger number of family‐based studies, are warranted for conclusive evaluation of the COMT val158met polymorphism as a vulnerability factor in panic disorder.

Serotonergic genes have been implicated in the pathogenesis of depression probably via their influence on neural activity during emotion processing. This study used an imaging genomics approach to investigate amygdala activity in major depression as a function of common functional polymorphisms in the serotonin transporter gene (5‐HTTLPR) and the serotonin receptor 1A gene (5‐HT1A‐1019C/G). In 27 medicated patients with major depression, amygdala responses to happy, sad and angry faces were assessed using functional magnetic resonance imaging at 3 Tesla. Patients were genotyped for the 5‐HT1A‐1019C/G and the 5‐HTTLPR polymorphism, including the newly described 5‐HTT‐rs25531 single nucleotide polymorphism. Risk allele carriers for either gene showed significantly increased bilateral amygdala activation in response to emotional stimuli, implicating an additive effect of both genotypes. Our data suggest that the genetic susceptibility for major depression might be transported via dysfunctional neural activity in brain regions critical for emotion processing.

The lifetime prevalence of panic disorder (PD) is up to 4% worldwide and there is substantial evidence that genetic factors contribute to the development of PD. Single-nucleotide polymorphisms (SNPs) in TMEM132D, identified in a whole-genome association study (GWAS), were found to be associated with PD in three independent samples, with a two-SNP haplotype associated in each of three samples in the same direction, and with a P-value of 1.2e−7 in the combined sample (909 cases and 915 controls). Independent SNPs in this gene were also associated with the severity of anxiety symptoms in patients affected by PD or panic attacks as well as in patients suffering from unipolar depression. Risk genotypes for PD were associated with higher TMEM132D mRNA expression levels in the frontal cortex. In parallel, using a mouse model of extremes in trait anxiety, we could further show that anxiety-related behavior was positively correlated with Tmem132d mRNA expression in the anterior cingulate cortex, central to the processing of anxiety/fear-related stimuli, and that in this animal model a Tmem132d SNP is associated with anxiety-related behavior in an F2 panel. TMEM132D may thus be an important new candidate gene for PD as well as more generally for anxiety-related behavior.

The monoamine oxidase A (MAOA) gene has been suggested as a prime candidate in the pathogenesis of panic disorder. In the present study, DNA methylation patterns in the MAOA regulatory and exon 1/intron 1 region were investigated for association with panic disorder with particular attention to possible effects of gender and environmental factors. Sixty-five patients with panic disorder (44 females, 21 males) and 65 healthy controls were analysed for DNA methylation status at 42 MAOA CpG sites via direct sequencing of sodium bisulfate treated DNA extracted from blood cells. The occurrence of recent positive and negative life events was ascertained. Male subjects showed no or only very minor methylation with some evidence for relative hypomethylation at one CpG site in intron 1 in patients compared to controls. Female patients exhibited significantly lower methylation than healthy controls at 10 MAOA CpG sites in the promoter as well as in exon/intron 1, with significance surviving correction for multiple testing at four CpG sites (p≤0.001). Furthermore, in female subjects the occurrence of negative life events was associated with relatively decreased methylation, while positive life events were associated with increased methylation. The present pilot data suggest a potential role of MAOA gene hypomethylation in the pathogenesis of panic disorder particularly in female patients, possibly mediating a detrimental influence of negative life events. Future studies are warranted to replicate the present finding in independent samples, preferably in a longitudinal design.

Previous studies on the effects of serotonin receptor 1A (5-HT1A) gene variation on treatment response in depression revealed inconsistent results with studies pointing towards a detrimental influence of the 5-HT1A-1019G allele on antidepressant treatment response, while others did not discern any involvement of 5-HT1A variants. In order to further delineate the impact of 5-HT1A gene variation on pharmacoresponse in depression over 6 weeks of antidepressant treatment, the influence of the 5-HT1A-1019C/G (rs6295) polymorphism was investigated in 340 Caucasian patients with a Major Depressive Episode (DSM-IV) with particular attention to the subtype of depression (major depression and melancholic depression). Antidepressant treatment response across 5-HT1A-1019C/G genotype groups showed no differences in either Major Depressive Episode or major depression between genotype groups, whereas stratification for the melancholic subtype of depression revealed a significantly worse treatment response as conferred by the -1019CC genotype (p=0.02). The poorer treatment response in melancholic depression could first be detected in week 2 (p=0.03), continuing until week 6 and showing a maximum effect in week 3 (p=0.01). The present study adds to the clarification of the role of 5-HT1A variation in treatment response in major depression by providing preliminary support for poor treatment response mediated by the 5-HT1A-1019C allele repressing 5-HT1A activity specifically in the melancholic subtype of depression.

Previous studies on neuronal activation correlates of panic attacks were mostly based on challenge tests, sensory-related stimulation or fear conditioning in healthy subjects. In the present study, we report on a female patient with panic disorder experiencing a spontaneous panic attack under an auditory habituation paradigm in the last stimulation block with sine tones captured with fMRI at 3T. The panic attack was associated with a significantly increased activity in the right amygdala. This is the first report on neuronal activation correlates of a spontaneous panic attack in a patient with panic disorder as measured by fMRI, which lends further support to a pivotal role of the amygdala in the pathogenesis of the disease.

A recent genome-wide association study in patients with panic disorder (PD) identified a risk haplotype consisting of two single-nucleotide polymorphisms (SNPs) (rs7309727 and rs11060369) located in intron 3 of TMEM132D to be associated with PD in three independent samples. Now we report a subsequent confirmation study using five additional PD case–control samples (n=1670 cases and n=2266 controls) assembled as part of the Panic Disorder International Consortium (PanIC) study for a total of 2678 cases and 3262 controls in the analysis. In the new independent samples of European ancestry (EA), the association of rs7309727 and the risk haplotype rs7309727–rs11060369 was, indeed, replicated, with the strongest signal coming from patients with primary PD, that is, patients without major psychiatric comorbidities (n=1038 cases and n=2411 controls). This finding was paralleled by the results of the meta-analysis across all samples, in which the risk haplotype and rs7309727 reached P-levels of P=1.4e−8 and P=1.1e−8, respectively, when restricting the samples to individuals of EA with primary PD. In the Japanese sample no associations with PD could be found. The present results support the initial finding that TMEM132D gene contributes to genetic susceptibility for PD in individuals of EA. Our results also indicate that patient ascertainment and genetic background could be important sources of heterogeneity modifying this association signal in different populations.

Epigenetic signatures such as methylation of the monoamine oxidase A (MAOA) gene have been found to be altered in panic disorder (PD). Hypothesizing temporal plasticity of epigenetic processes as a mechanism of successful fear extinction, the present psychotherapy-epigenetic study for we believe the first time investigated MAOA methylation changes during the course of exposure-based cognitive behavioral therapy (CBT) in PD. MAOA methylation was compared between N=28 female Caucasian PD patients (discovery sample) and N=28 age- and sex-matched healthy controls via direct sequencing of sodium bisulfite-treated DNA extracted from blood cells. MAOA methylation was furthermore analyzed at baseline (T0) and after a 6-week CBT (T1) in the discovery sample parallelized by a waiting time in healthy controls, as well as in an independent sample of female PD patients (N=20). Patients exhibited lower MAOA methylation than healthy controls (P<0.001), and baseline PD severity correlated negatively with MAOA methylation (P=0.01). In the discovery sample, MAOA methylation increased up to the level of healthy controls along with CBT response (number of panic attacks; T0–T1: +3.37±2.17%), while non-responders further decreased in methylation (−2.00±1.28%; P=0.001). In the replication sample, increases in MAOA methylation correlated with agoraphobic symptom reduction after CBT (P=0.02–0.03). The present results support previous evidence for MAOA hypomethylation as a PD risk marker and suggest reversibility of MAOA hypomethylation as a potential epigenetic correlate of response to CBT. The emerging notion of epigenetic signatures as a mechanism of action of psychotherapeutic interventions may promote epigenetic patterns as biomarkers of lasting extinction effects.

The pathogenesis of anxiety disorders is considered to be multifactorial with a complex interaction of genetic factors and individual environmental factors. Therefore, the aim of this study was to examine gene‐by‐environment interactions of the genes coding for catechol‐O‐methyltransferase (COMT) and monoamine oxidase A (MAOA) with life events on measures related to anxiety. A sample of healthy subjects (N = 782; thereof 531 women; mean age M = 24.79, SD = 6.02) was genotyped for COMT rs4680 and MAOA‐uVNTR (upstream variable number of tandem repeats), and was assessed for childhood adversities [Childhood Trauma Questionnaire (CTQ)], anxiety sensitivity [Anxiety Sensitivity Index (ASI)] and anxious apprehension [Penn State Worry Questionnaire (PSWQ)]. Main and interaction effects of genotype, environment and gender on measures related to anxiety were assessed by means of regression analyses. Association analysis showed no main gene effect on either questionnaire score. A significant interactive effect of childhood adversities and COMT genotype was observed: Homozygosity for the low‐active met allele and high CTQ scores was associated with a significant increment of explained ASI variance [R2 = 0.040, false discovery rate (FDR) corrected P = 0.04]. A borderline interactive effect with respect to MAOA‐uVNTR was restricted to the male subgroup. Carriers of the low‐active MAOA allele who reported more aversive experiences in childhood exhibited a trend for enhanced anxious apprehension (R2 = 0.077, FDR corrected P = 0.10). Early aversive life experiences therefore might increase the vulnerability to anxiety disorders in the presence of homozygosity for the COMT 158met allele or low‐active MAOA‐uVNTR alleles.

SummarySeveral lines of evidence suggest an involvement of adenosine A2a receptor (A2aAR) mediated adenosinergic neuromodulation in the etiopathogenesis of schizophrenia. We therefore perfomed a systematic mutation scan of the complete coding region of the human A2aAR gene in a sample of 42 schizophrenic patients. We detected one rare naturally occurring receptor variant (Gly-340-Ser) and two silent mutations (405C/T and 1083C/T). To our knowledge the Gly-340-Ser substitution is the first naturally occurring molecular variant of the A2aAR identified. Determining the frequency of the three variants in 42 unrelated healthy controls, we observed a significant trend towards an overrepresentation of the 1083T variant in patients when compared to controls (p=0.041). This trend was followed up in a large independent replication sample. However, we were not able to confirm the original trend in the second sample (p=0.367). The Ser-340 variant was found in a single schizophrenic individual. Investigation of the patients family revealed independent segregation between the Ser-340 variant and psychiatric illness. Our data suggest that genetically determined structural variation of the A2aAR does not play a major role in the development of schizophrenia.
