What the grant funds
The purpose of this initiative is to support projects which exploit genome or epigenome editing to functionally validate and characterize genes or variants involved in substance use disorder-relevant phenotypes. It is expected that any genetic resources generated will be made broadly available to the scientific community to enable investigation of the relevant neurobiological mechanisms involved and provide critical foundational knowledge for the development of future prevention, diagnostic, and therapeutic strategies.
