noahisaac writes "My brother just sent me an article he posted for the Rett Syndrome Research Foundation about a cure for Rett Syndrome, a form of autism. According to the article, researchers successfully re-introduced a fully functional version of the MECP2 gene into mice that had been born with damaged MECP2 genes. Contrary to their expectations, the mice improved. In the article's words, '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.' The ramifications for people suffering from Rett Syndrome are obvious, but mutations of the MECP2 gene are also believed to be the cause of 'classic' autism, and a number of other neurological disorders."
