The PTSD group was formed in 2013, which grew out of the PGC that started in 2007 to conduct field- wide mega-analyses of individual data for ADHD, autism, bipolar disorder, major depression, and schizophrenia. The PGC, which united the field for the first time as an enormous consortium (500+ scientists from 80+ institutions in 25 countries), has already produced several major findings of genetic architecture for psychiatric disorders. The PGC-PTSD operates relatively autonomously under the PGC consistent with a “state rights” model of governance.
