Rett Syndrome is reversed in genetic mouse model Cincinnati, OH (February 08, 2007) / PRNewswire / — The Rett Syndrome Research Foundation (RSRF) announces results of a landmark study reversing the symptoms of Rett Syndrome (RTT) in a genetic mouse model. The findings, by Adrian Bird, Ph.D., of the University of Edinburgh and Chairman of the RSRF Scientific Advisory Board, appear online in Science Express on February 8, 2007. Rett Syndrome is a severe childhood neurological disease that is the most physically disabling of the autism spectrum disorders. The experiments were funded by the Rett Syndrome Research Foundation (RSRF), the Wellcome Trust and the Rett Syndrome U.K./Jeans for Genes. Caused by mutations in the gene MECP2, RTT affects primarily girls, striking at random in early childhood and destroying speech, normal movement and functional hand use. Many children become wheelchair bound; those who walk display an abnormal, stiff-legged gait. Disordered breathing patterns and Parkinson-like tremors are common. Restoration of fully functional MECP2 over a four week period eradicated tremors and normalized breathing, mobility and gait in mice that had previously been fully symptomatic and, in some cases, only days away from death.
