After an initial meeting of the chairs at the WCPG 2016 in Jerusalem, the PGC Anxiety Workgroup became part of the PGC in 2017 with a kick-off meeting during WCPG 2017 in Orlando. Since then, our membership has grown to include over 30 groups from about 10 countries.
We are conducting genome-wide association studies (GWAS) based on statistically powerful samples of patients with anxiety disorders and healthy individuals with data on anxiety measures. Our long-term objective is to provide further insight into the pathophysiology and neurobiological underpinnings of anxiety disorders through the identification of genetic risk variants, leading to the development of novel treatments or biomarkers.
Our analyses will include GWAS in (i) categorical case-control samples (panic disorder, agoraphobia, generalized anxiety disorder, social phobia and specific phobia), (ii) population based samples with dimensional anxiety measures (e.g. GAD-7, STAI, ACQ, ASI), and (iii) samples with information on response to treatment for anxiety disorders. We are also keen to aid parallel GWAS consortium efforts (CAPICE, EAGLE) on the development of anxiety disorders in childhood and adolescence, and to contribute to post-genomic research on anxiety, capitalising on genome sequence and epigenetic data.
We welcome anyone who is interested to join us. We are eager to collaborate with investigators who might be willing to share raw phenotypic/genotypic/other omic data or genetic effect sizes via summary statistics.
We welcome anyone who is interested to join us. For further information please contact the workgroup chairs Jürgen Deckert, Thalia Eley, and John (Jack) Hettema or email the group at email@example.com.
We are working on our first official PGC Anxiety publication – watch this space!
