2024 marks the 50th anniversary of the TSC Alliance®! Throughout the year, we’ll celebrate five decades of progress as well as look forward with much promise for the future.

Join in the celebration by attending our 50th Anniversary Gala in New York City on Friday, October 25, 2024. Get your tickets now!

In 1974 four moms refused to accept the status quo.

They formed an organization and in doing so started a community. For the next 50 years this organization and community have forever changed what we know about tuberous sclerosis complex and what living with this disease looks like. It has been:

50 years of transformation.

We started as the National Tuberous Sclerosis Association, then the Tuberous Sclerosis Alliance and finally the TSC Alliance today. And while our name has changed our commitment to creating a future where every person and family affected by TSC has what they need to live their fullest lives endures.

50 years of progress.

Where advancements in research have led to everything from the discovery of the two TSC genes to the approval of three FDA drugs specifically for TSC. Where collaboration amongst compassionate doctors have led to consensus guidelines that have improved clinical care globally. And where those four moms soon became a network of thousands around the world dedicated to supporting everyone affected by TSC.

50 years of promise.

We are shifting the paradigm; new studies are exploring not just how we treat manifestations of TSC but whether we can prevent them entirely. We are braving new frontiers and taking on the most challenging aspects of this disease. We move forward confidently, because for five decades we have overcome adversity time and time again.

The TSC Alliance stands on the shoulders of those who came before us. But while we honor our past, we also look to the future because our work is not yet done. This is just the start of our story.

50 forward.
