The International Society of Psychiatric Genetics (ISPG) warmly invites you to attend the World Congress of Psychiatric Genetics (WCPG), September 13-17, 2022 in Florence, Italy. These are exciting times in psychiatric genetics. With unprecedented data availability, thanks to international efforts, we are moving from gene-identification to understanding mechanisms of psychiatric disorders, allowing for a rethinking of psychiatric categorization and for new intervention approaches to be envisaged. The WCPG is the premier international scientific meeting for research in psychiatric genetics and related areas. Leading experts of genetics, neuroscience, and psychiatry from all over the world will be participating.
