With $245,000 in grants from FRAXA Research Foundation, Dr. Stephen Warren and his lab at Emory University studied all aspects of Fragile X syndrome, from the mechanisms of repeat expansion to high-throughput drug screens in the Drosophila model of Fragile X. The Warren lab made the original discovery of the Fragile X gene, FMR1, in collaboration with the Nelson and Oostra labs, and is recognized internationally as a leader in molecular genetics. Recent projects include establishment of induced pluripotent stem cell lines from Fragile X patients, and determination of other forms of mutation in the Fragile X gene, other than the most common trinucleotide repeat expansion.
