Financial Status, Terms & Policies


The International Rett Syndrome Foundation (IRSF) was formed on July 1st, 2007 when the International Rett Syndrome Association (IRSA) and the Rett Syndrome Research Foundation (RSRF) consolidated resources in a historic merger.

The International Rett Syndrome Association was formed in 1984 when a determined group of parents (led by Kathy Hunter) banned together to try to fund research for cures and treatments, support other families with Rett syndrome, and raise public awareness. Over the years the organization raised tremendous public awareness, brought life-changing care to families, and helped foster and fund some significant research breakthroughs (including the discovery of the MECP2 gene that causes Rett syndrome).
