Scientists at MIT have had success reversing some symptoms of mental retardation and autism. After performing their tests on lab mice, researchers say that by altering one gene they were able to significantly alleviate a wide range of abnormalities associated with "Fragile X Syndrome".
Fragile X Syndrome is a disease that affects about 100,000 Americans and is a common, inherited cause of mental retardation and autism.
The altering of this one gene improved brain development, restored normal body growth, and reduced seizures, which are all symptoms of Fragile X Syndrome.
Scientists say that experimental drugs could work the same way and are expected to start clinical trials in humans soon.
