Finding may explain many brain disorders, lead to prevention and treatment.
A new study led by Weill Cornell Medical College scientists shows that the most common genetic form of mental retardation and autism occurs because of a mechanism that shuts off the gene associated with the disease. The findings, published today in Science, also show that a drug that blocks this silencing mechanism can prevent fragile X syndrome — suggesting similar therapy is possible for 20 other diseases that range from mental retardation to multisystem failure.
The research is in Science. (full access paywall)
