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. 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.
