The symptoms of a severe brain disorder similar to autism, which affects around 10,000 UK children, could be reversed, scientists believe. | The symptoms of a severe brain disorder similar to autism, which affects around 10,000 UK children, could be reversed, scientists believe. |
Scottish researchers made symptoms of Rett syndrome disappear in mice by activating a single gene, the magazine Science reports. | |

The scientists from the universities of Edinburgh and Glasgow hope their discovery will encourage further research aimed at discovering a treatment for the syndrome. | |

When the gene was activated in mice which had been born with MECP2 switched off, disease symptoms such as breathing and mobility problems stopped. | When the gene was activated in mice which had been born with MECP2 switched off, disease symptoms such as breathing and mobility problems stopped. |
Within a few weeks the affected mice were largely indistinguishable from their healthy counterparts. | Within a few weeks the affected mice were largely indistinguishable from their healthy counterparts. |
Researcher Dr Stuart Cobb, from Glasgow University, said: "This breakthrough provides a small piece of hope for sufferers. | |
"It had been thought the disorder was caused by abnormal development - but activating the MECP2 gene, even in adulthood, proved to be effective in reversing neurological symptoms. | "It had been thought the disorder was caused by abnormal development - but activating the MECP2 gene, even in adulthood, proved to be effective in reversing neurological symptoms. |
"Analysing the communication between nerves in the brain, we discovered that abnormal signalling is also rectified when MECP2 gene is switched back on. | "Analysing the communication between nerves in the brain, we discovered that abnormal signalling is also rectified when MECP2 gene is switched back on. |
