What is Fragile X Syndrome?

Fragile X syndrome (FXS) is the most common inherited cause of autism and intellectual disabilities. It affects 1 in 4,000 boys and 1 in 6,000 girls worldwide.

Fragile X syndrome occurs when a single gene on the X chromosome shuts down. This gene makes a protein needed for normal brain development. In FXS it does not work properly, the protein is not made, and the brain does not develop as it should.

How Does FRAXA Help?

FRAXA’s mission is to find effective treatments and ultimately a cure for Fragile X syndrome. We directly fund research grants and fellowships at top universities around the world. We partner with biomedical and pharmaceutical companies, large and small, to bridge the gap between research discoveries and actual treatments.

Treatments for Fragile X are likely to help people affected by autism, Alzheimer’s, and other brain disorders.

Latest Fragile X News & Updates

How Promising is CRISPR for Fragile X?

Dave Bjork, Director of Community Relations, recently sat down with Peter Todd, MD, PhD, Assistant Professor in the Department of Neurology in the University of Michigan Medical School. Dr. Todd was recently awarded a FRAXA Research Grant for gene reactivation with the use of CRISPR. In this interview he tells us about CRISPR in Fragile X research, how realistic is it that it could turn the Fragile X gene back on, and if it can really be a cure for Fragile X.

Niagara Falls went Teal for Fragile X Awareness

On Sunday, July 22 at 10:00 pm, Niagara Falls was lit up teal to honor National Fragile X Awareness Day! We are extremely grateful to the Niagara Falls Illumination Board for making this happen. The teal lighting created a spectacular experience for all the spectators on both sides of the falls. FRAXA co-founders Katie Clapp and Michael Tranfaglia made the drive from Massachusetts, and our web developer, Eric Welin, trekked to the falls with his entire family. Our afternoon meet up at Goat Island included Fragile X families from Canada, Illinois, Kentucky, New York and South Africa! Several happy Fragile X self-advocates could be seen running around with their siblings, while everyone enjoyed the Fragile X family reunion. It was great to see all of the different Fragile X shirts our friends wore.

Retinoic Acid Signaling Blocked by Fragile X Mutation

A 2013-2014 FRAXA Research Grant, Synaptic Characterization of Human Fragile X Neurons, has shown that the Fragile X mutation impairs homeostatic plasticity in human neurons, by blocking synaptic retinoic acid signaling. Principal Investigator Marius Wernig, PhD and FRAXA Postdoctoral Fellow Samuele Marro, PhD at Stanford University used stem cells from human adults, instead of mouse cells, for this study. They found promising results with retinoic acid which is a metabolite of Vitamin A. The system they have developed could provide a powerful new cellular biomarker for screening many treatment approaches. Dr. Marro provided us with the following summary of the published results.
