Negative effect of treatment with mGluR5 negative allosteric modulator AFQ056 on blood biomarkers in young individuals with Fragile X syndrome

SAGE Open Medicine
Background: Fragile X syndrome, with an approximate incidence rate of 1 in 4000 males to 1 in 8000 females, is the most prevalent genetic cause of heritable intellectual disability and the most common monogenic cause of autism spectrum disorder. The full

Unraveling in vitro phase separation and aggregation properties of the structured region of FMRP and the impact of Fragile X syndrome‐linked mutations

The FEBS Journal, EarlyView.
Fragile X messenger ribonucleoprotein 1 (FMRP) is a multidomain RNA‐binding protein associated with Fragile X Syndrome (FXS). We found that its N‐terminal structured region has an intrinsic propensity to undergo liquid–liquid phase separation and fibril formation. FXS‐associated mutations perturb protein stability and aggregation propensity, suggesting

FMR1 deletion in rats induces hyperactivity with no changes in striatal dopamine transporter availability

Scientific Reports, 2022
Autism Spectrum Disorder (ASD) is a pervasive neurodevelopmental disorder emerging in early life characterized by impairments in social interaction, poor verbal and non-verbal communication, and repetitive patterns of behaviors.

Autonomic Function in Fragile X Syndrome: A Systematic Review

Journal of Intellectual Disability Research, EarlyView.
ABSTRACT Background Fragile X syndrome (FXS) is a monogenic X‐linked cause of intellectual disability and autism. Individuals with FXS often have high levels of anxiety and sometimes display challenging behaviours. Autonomic dysfunction has been suggested to be one physiological mechanism that may contribute to these.

Social cognition in children and adolescents with fragile X syndrome: A comparison with individuals with autism symptoms and typical development

Journal of Neuropsychology, EarlyView.
Abstract Most individuals with fragile X syndrome (FXS) exhibit symptoms of autism spectrum disorder (ASD), suggesting a substantial overlap in social cognitive profiles. This cross‐sectional study aimed to explore social cognitive abilities in children and adolescents with FXS in comparison with an age‐matched heterogeneous ASD group and typically ...

Endogenous Engineering Reprograms Extracellular Vesicles for Enhanced Therapeutic Function

Advanced Science, Volume 13, Issue 36, 29 June 2026.
This review explains how Extracellular vesicles‐producing cells can be endogenously engineered to load therapeutic proteins and nucleic acids. We summarize physiological and genetic strategies that harness native sorting pathways for selective cargo loading.

Role of the endocannabinoid system in fragile X syndrome: potential mechanisms for benefit from cannabidiol treatment

Journal of Neurodevelopmental Disorders, 2023
Multiple lines of evidence suggest a central role for the endocannabinoid system (ECS) in the neuronal development and cognitive function and in the pathogenesis of fragile X syndrome (FXS).
