Candidate genes in panic disorder: meta-analyses of 23 common variants in major anxiogenic pathways.

The utilization of molecular genetics approaches in examination of panic disorder (PD) has implicated several variants as potential susceptibility factors for panicogenesis. However, the identification of robust PD susceptibility genes has been complicated by phenotypic diversity, underpowered association studies and ancestry-specific effects. In the present study, we performed a succinct review of case-control association studies published prior to April 2015.

Genome-wide Association Study of Autism Spectrum Disorder in the East Asian Populations.

Autism spectrum disorder is a heterogeneous neurodevelopmental disorder with strong genetic basis. To identify common genetic variations conferring the risk of ASD, we performed a two-stage genome-wide association study using ASD family and healthy control samples obtained from East Asian populations. A total of 166 ASD families (n = 500) and 642 healthy controls from the Japanese population were used as the discovery cohort.

A polymorphism in CCR1/CCR3 is associated with narcolepsy.

Etiology of narcolepsy-cataplexy involves multiple genetic and environmental factors. While the human leukocyte antigen (HLA)-DRB1*15:01-DQB1*06:02 haplotype is strongly associated with narcolepsy, it is not sufficient for disease development. To identify additional, non-HLA susceptibility genes, we conducted a genome-wide association study (GWAS) using Japanese samples.

Immune-related pathways including HLA-DRB1(∗)13:02 are associated with panic disorder.

Panic disorder (PD) is an anxiety disorder characterized by panic attacks and anticipatory anxiety. Both genetic and environmental factors are thought to trigger PD onset. Previously, we performed a genome-wide association study (GWAS) for PD and focused on candidate SNPs with the lowest P values.

DNA polymorphism in the FKBP5 gene affects impulsivity in intertemporal choice.

Introduction: Impulsivity in intertemporal choice has been operationalized as "delay discounting", referring to the preference for a sooner, smaller reward. FK506 binding protein 5 (FKBP5) is a co-chaperone of the glucocorticoid receptor (GR). FKBP5 overexpression causes GR resistance, resulting in increased plasma cortisol levels.
