Creating a World without Rett Syndrome

Today, as the International Rett Syndrome Foundation, we continue our almost 40-year commitment to creating a world without Rett. We remain focused on accelerating research to treat and cure Rett syndrome as we empower families with information, knowledge, and connectivity.

Our Impact

Through IRSF and our legacy foundations’ investments, we are continuing to change the landscape of Rett syndrome.

  • Convened parents and experts to publish the Rett Syndrome Handbook
  • Designated 15 Rett Syndrome Centers of Excellence

Strong Foundations

In 1983, a small dedicated group of parents whose children had Rett syndrome formed the first non-profit to focus exclusively on Rett syndrome – International Rett Syndrome Association (IRSA). In 2007, IRSA and Rett Syndrome Research Foundation (RSRF) consolidated resources to better serve families and maximize research investments toward a cure. The International Rett Syndrome Foundation (IRSF) emerged with a mission to accelerate research and empower families that builds upon these foundations’ pioneering work toward care and cure.
