On May 15, the TSC Alliance® will join tuberous sclerosis complex (TSC) organizations around the world to observe the 11th Annual TSC Global Awareness Day. On this day, thousands of individuals and families affected by TSC will come together to increase public awareness of the rare disease and share their stories of hope for the future. TSC Global Awareness Day is sponsored internationally by Tuberous Sclerosis Complex International (TSCi), a worldwide consortium of TSC organizations of which the TSC Alliance is a member.
