Girls and women with Fragile X syndrome show different learning impairments relative to boys and men with the disease, a finding that was paralleled in a mouse model of the disease, a study found.

Aggression, Other Fragile X Behaviors Tend to Ease Over Teenage Years
Behavioral problems such as hyperactivity and aggression are generally more frequent in younger children with Fragile X syndrome, becoming less common as they grow through adolescence and journey toward adulthood, researchers report.
Read morePivotal Phase 3 Trial of Zygel in Severe Fragile X Possible This Year
Zynerba Pharmaceuticals reported receiving advice from the U.S. Food and Drug Administration (FDA) on the design of an upcoming Phase 3 clinical trial meant to confirm previous trial findings supporting Zygel as a cannabidiol treatment in a specific subset of Fragile X syndrome patients. The new trial, called RECONNECT, is expected to launch before October, and will mainly enroll children and adolescents with a complete (100%) methylation of FMR1, the gene mutated in Fragile X.
Read moreParkinson’s Therapy May Hold Promise for Fragile X
A study funded by FRAXA in Italy has encouraging results for people with Fragile X: drugs that block adenosine receptors (A2A) reversed signs of Fragile X in a mouse model.
“One of the most intriguing things about this study is that it points to an entire drug class (not just the one drug used) as potentially therapeutic for Fragile X. Many available compounds block A2A receptors, and we know they are safe and effective.

The two COVID-19 vaccines that recently received emergency approval from the US and other worldwide regulatory agencies are expected to pose little risk to the rare disease community, including to patients with compromised immune systems or those participating in gene therapy studies.
Read moreBryostatin-1 in Long-term Use Seen to Arrest Fragile X Symptoms in Mouse Model
Long-term, but not short-term, treatment with bryostatin-1 — Neurotrope’s lead investigational therapy — arrested such behavioral and cognitive symptoms as hyperactivity, difficulties with daily life activities, and learning and memory deficits in a mouse model of Fragile X syndrome.
Read moreZygel May Improve Behavior in Children With Severe Fragile X, Trial Data Suggest
Zynerba presented clinical trial results for Zygel at a recent neurology conference. Zygel, an experimental cannabidiol (CBD) gel, may reduce behavioral abnormalities in children with Fragile X syndrome who have more severe disease.
Read moreCompanies Move to Advance Potential Cognitive Treatment for Fragile X
Tetra Therapeutics and Shionogi announced plans to expand their partnership supporting BPN14770, a treatment candidate for disorders marked by cognitive and memory deficits, including Fragile X syndrome and Alzheimer’s disease. The agreement builds on an earlier collaboration between the two companies, and aims to further accelerate BPN14770’s development and potential marketing. It is currently in clinical testing in both Fragile X and Alzheimer’s patients.
Read moreLess Active Immune System Evident in Fragile X Patients, Study Suggests
People with Fragile X syndrome are more likely to develop infections, but are less susceptible to autoimmune disorders than the overall population, a new study found. Taken together, this suggests that the immune system is underactive in this patient population. The study, titled, “The phenotypical implications of immune dysregulation in Fragile X syndrome,” was published in the European Journal of Neurology.
Read moreNew Partners Aim to Accelerate the Discovery and Repurposing of Medicines for Rare Neurological Diseases
First Healx secured $56M in new financing to launch a global Rare Treatment Accelerator program to tackle Fragile X syndrome and 39 other rare diseases. Now they have built a partnership with Boehringer Ingelheim worth millions. It all started with a small FRAXA grant to Healx to repurpose available drugs for Fragile X.
Read moreFXS Patients’ Social Deficits are Linked to Social Anxiety, Eye-tracking Study Says
Dr. Craig Erickson and colleagues at the University of Cincinnati used eye-tracking technology to understand sociability in Fragile X syndrome. This study affirms what so many parents, caretakers, and educators suspect: people with fragile X want to be social, and it is anxiety – not lack of interest – which usually hold them back. If anxiety could be reduced, more sociability would likely follow. Dr. Erickson is a Fragile X expert and FRAXA investigator who is currently conducting a Fragile X clinical trial of an investigational new drug.

Patients with Fragile X syndrome who don’t meet the cut-off for a diagnosis of autism show a decrease in impulsivity and repetitive questioning over time, when compared with patients who do, a new study shows.
