The Hierarchical Taxonomy of Psychopathology


Genetics Workgroup


The workgroup charter is to study the interface between genetic research and the hierarchical structure of psychopathology dimensions. The overarching goal is to investigate how dimensional structural models such as HiTOP dovetail with our existing understanding of the transdiagnostic genetic architecture of psychopathology, and how quantitative and hierarchically organized phenotypes can facilitate future psychiatric genetic research. The scope spans both quantitative (i.e. twin and adoption studies) and molecular genetics research, including downstream genomic processes such as epigenetics and gene expression. The workgroup will aim to establish close collaborations with external researchers, consortia and datasets in the field of psychiatric and behavioral genetics.
