Researchers found a pathway in astrocytes that is overactive in Fragile X syndrome, and they hope to bring this pathway back to normal with a drug.
Memorial Tribute to Dr. Stephen T. Warren
Dr. Stephen T. Warren, who discovered the Fragile X gene (FRAXA) in 1991, passed away June 6, 2021. Donations in his honor support FRAXA Research.
Meet Tyler!
Meet #FriendofFRAXA Tyler! If you would like to nominate someone as a #FriendofFRAXA, we welcome all who have been touched by Fragile X, including friends, grandparents, siblings, professionals and companions alike to become a #FriendofFRAXA with the goal of putting a face to Fragile X for those who may not know someone directly.
Identifying Cellular and Molecular Signatures in Human Neurons That Distinguish Fragile X Syndrome Patients with Divergent EEG Profiles
Just as Fragile X affects individuals differently, medications do as well. This project aims to bring personalized medicine to Fragile X syndrome.
Drug Tolerance in MGluR5 Clinical Trials – Dr Patrick McCamphill 1:1 with FRAXA
We have long suspected that the clinical trials of mGluR5 blockers from Novartis and Roche failed because the drug triggered tolerance, losing effect over time. With a $90,000 grant from FRAXA, Dr. Patrick McCamphill, a Postdoctoral Fellow in the MIT lab of Dr. Mark Bear, is investigating. He does indeed find tolerance, and now he is looking for ways to overcome it.
We Started Out Small, Now Look…
Join FRAXA in lighting up the world on July 22 for World Fragile X Day—together, we shine teal for Fragile X awareness!
NPR Feature – A Fragile X Treatment May Be On The Horizon
NPR’s Jon Hamilton looks back on a decade of Fragile X progress and the Tranfaglia family’s quest for a cure. Hear their story on NPR Short Wave.
Pharmacotherapeutic Effects of Cannabidiol (CBD) in Fragile X syndrome (FXS) and Autism Spectrum disorder (ASD)
This study tested CBD (cannabidiol) treatment in male and female Fragile X mice to learn how and why it works and whether gender affects responses to CDB treatment.
NPR Short Wave, “A Fragile X Treatment May Be On The Horizon”
Katie Clapp and Michael Tranfaglia’s son was born with a genetic disorder that affects brain development. It makes it hard to learn language and basic daily tasks and often is accompanied by a host of other disorders. To help find a cure, they started a foundation and raised research money. After se…
Holly Roos Joins the FRAXA Team!
We’re thrilled to welcome Holly Roos, longtime Fragile X advocate, as FRAXA’s new Community Services Director!
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.
Cellular-Specific Therapeutic Targeting of Inhibitory Circuits in Fragile X Syndrome
The team studied how inhibitory brain circuits malfunction in Fragile X and tested ways to restore balance by targeting mGluR and endocannabinoid signaling.
FRAXA Supports Increased Funding for NICHD
FRAXA has joined the Friends of NICHD coalition, urging increased government funding for research into Fragile X and related conditions.
Auditory Dysfunction in Fragile X Syndrome in a Mouse Model of Fragile X
FRAXA-funded studies found Fragile X mice show altered auditory circuit function with delayed startle timing and reduced prepulse inhibition, mirroring human sound sensitivity.
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.
Educating Young Children with Fragile X Syndrome
We share strategies, tips, techniques, and stories to help teachers and therapists who are working with young children who have Fragile X syndrome.
The Why and How of FRAXA’s Work to Find a Cure for Fragile X
Thank you Talk Fragile X for having FRAXA’s cofounder Katie Clapp as a guest on your podcast! It was a pleasure to share why FRAXA got started and our motivation for finding effective treatments and ultimately a cure for Fragile X syndrome.
Fragile X Research Funding of $1 Million Offered for 2021
FRAXA plans to fund $1 million for a generous number of Fragile X research grants and fellowships in 2021. Our mission is to find specific treatments and ultimately a cure for Fragile X syndrome. We aim to bring practical treatment into current medical practice as quickly as possible; we prioritize projects that have a clear practical application and the results of which will be shared in a timely fashion.
Integrating Human and Mouse Studies in Fragile X Syndrome – an NIH Center Approach
Presentations by Craig Erickson, Ernest Pedapati, Devin Binder, and Kimberly Huber about their research on Fragile X as part of their NIH Center of Excellence.
Developing Arbaclofen for Fragile X – Dr. Mark Bear 1:1 with FRAXA
Seven years ago, arbaclofen (STX209) was pulled from development, disappointing families around the US. Now MIT professor and FRAXA Investigator Dr. Mark Bear has founded Allos Pharma to bring it back. Dr. Bear sat down with FRAXA co-founder Katie Clapp to share the story and next steps.
Towards Understanding the Role of FMRP in Human Brain Development Using Brain Organoids
Dr. Zhexing Wen and Dr. Peng Jin of the newly funded Fragile X Center of Excellence at Emory University School of Medicine join us in this seminar to present about Understanding the Role of FMRP in Human Brain Development Using Brain Organoids.
