Breakthrough in Treating Fragile X in Mice

Fragile X is caused by mutation of a gene called FMRl on the X chromosome.The mutation prevents the brain from developing properly.

Scientists at the University of California, Irvine, have claimed that they have found a way to improve and even restore cognitive function in people suffering from fragile X, the most commonly inherited form of learning disability.

Fragile X is caused by mutation of a gene called FMRl on the X chromosome.

New Screening Method Shows Promising Drug Targets for Fragile X Syndrome
By using a new drug screening method in Drosophila (fruit flies), researchers have identified several drugs and small molecules that reverse the features of fragile X syndrome.

The mutation prevents the brain from developing properly, leading to a form of mental retardation that has long been considered untreatable.

However, researchers, led by Julie Lauterborn, have now devised a new way to improve and even restore cognitive function not only in people suffering from fragile X, but in people with other cognitive impairments as well.

The finding is based on a recent discovery that a naturally occurring protein called brain-derived neurotrophic factor may improve and even restore cognitive function in people whose mental abilities are impaired.

Researchers Have Developed Mouse Model of Autism Spectrum Disorders
Scientists at the Howard Hughes Medical Institute researchers have genetically engineered mice that have the same genetic mutation

The neurotrophic factor is also involved in nerve growth,

The researchers observed positive results after injecting the protein into the brains of mice with fragile X syndrome.

Gene Alteration may Hold Cure for Fragile X Retardation Syndrome
A team of researchers including an India scientist have considerably reduced a wide range of abnormalities due to fragile X syndrome in mice by altering only a single gene.

However, they have not yet conducted any tests in humans, reports New Scientist.

The researchers claimed that the treatment is not limited to people with fragile X, as it could prove to be equally beneficial for people with other conditions that lead to learning disabilities, such as Down's syndrome and autism.
