Tuberous sclerosis complex is a genetic disorder that is characterized by tumor growth in various organs in the body, as well as neurological effects. Most people with TSC experience epilepsy early in life and many develop autism or other neuropsychiatric issues. The TSC Alliance has invested more than $37 million in research since 1984. Its efforts and collaborations have resulted in six U.S. Food and Drug Administration approved treatments for some aspects of the disease or related conditions. We spoke to Steve Roberds, chief scientific officer of the TSC Alliance, about the organization's success with crafting a research agenda, how it’s been able to invest in ways that catalyze research, and what it’s done to facilitate drug development by industry.
