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.
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 8,000 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.
The Latest from FRAXA
Brain & Life, “A Mom Leads Efforts to Cure Fragile X Syndrome for Her Son and Others”
We haven’t found a cure yet, but we’ve moved closer to understanding fragile X syndrome and identifying treatment targets. We hope this will help our son and other families dealing with this life-changing condition.

Tetra Releases Full Results of FRAXA-Funded Clinical Trial of PDE4D Inhibitor
Today, Tetra Therapeutics published the full results of its PDE4D trial published the full results to their announcement. Now having reviewed the full results, FRAXA can confidently say that the PDE4D drug trial gives hope to patients and families that Fragile X Syndrome is a treatable disorder, and this particular drug can improve intellectual disability.

Cellular-Specific Therapeutic Targeting of Inhibitory Circuits in Fragile X Syndrome
Studies have shown that the function of inhibitory networks is disturbed in Fragile X. This abnormality is not well understood but appears to be secondary to abnormalities in metabotropic glutamate and endocannabinoid systems. With a $90,000 grant from FRAXA, Dr. Molly Huntsman’s team examined how these networks interact and how inhibitory deficits can best be remedied.

Auditory Dysfunction in Fragile X Syndrome in a Mouse Model of Fragile X
With a $90,000 grant from FRAXA, Dr. McCullagh and Dr. Achem Klug at the University of Colorado investigated whether auditory neural circuits are altered in Fragile X mice. They saw minor differences in these mice compared to B6 (control) mice in several measures of auditory acuity. Fmr1 mice had increased latency to the startle response for almost all conditions compared to B6 mice, suggesting altered timing to acoustic cues. These experiments show that, consistent with patient reports and anatomical/physiological data, the auditory system is altered in a mouse model of FXS, though with some potential compensation leading to a subtle behavioral impact.

Clinical Trials and Cyclic AMP in Fragile X Syndrome: A Life Journey
In November 2020, a phase II clinical trial reported extremely successful results. This clinical trial of a PDE4D inhibitor from Tetra Pharmaceuticals was conducted by Dr. Elizabeth Berry-Kravis at Rush University Medical Center and funded by FRAXA Research Foundation. In this Simons Foundation lecture, Elizabeth Berry-Kravis traces 30 years of Fragile X research, from identifying its cause, through finding dozens of treatment targets, through a series of disappointing clinical trials.
