The purpose of this study is to investigate the effectiveness and tolerability of riluzole in adults with Fragile X Syndrome.
Fragile X Syndrome (FXS) represents the most common inherited form of intellectual disability. FXS is more common in males and the symptoms associated with the disorder are more marked in males. FXS is associated with characteristic physical features, behaviors, and comorbidities. Those with FXS often suffer from behavioral difficulties that include anxiety-related symptoms (shyness, social phobia, obsessive-compulsive disorder (OCD) symptoms), attention deficit hyperactivity symptoms (overarousal, hyperactivity, distractibility, impulsivity) and aggressive/self-injurious behaviors.
Riluzole is approved by the FDA for use in treating amyotrophic lateral sclerosis (ALS) in adults. Recently, riluzole has been the subject of several open-label studies describing the use of the drug in treatment-resistant depression and OCD.
Given the overlap between repetitive behavior in FXS and symptoms of OCD, it is logical to study riluzole in FXS given the compound's promise in ameliorating treatment-refractory symptoms of OCD.

This is a single center study at the UC Davis MIND Institute in patients age 3.5-16 years of age with fragile X syndrome (FXS), funded by a National Fragile X Foundation Grant. It is a con...
The purpose of this study is to determine whether NNZ-2566 is safe and well tolerated in the treatment of Fragile X Syndrome in adolescent and adult males.
This randomized, double-blind multiple ascending dose study will evaluate the safety and tolerability, pharmacokinetics and efficacy of RO4917523 in patients with Fragile X Syndrome. The p...
The purpose of this study is to determine the effects induced by lovastatin and minocycline in participants with fragile X syndrome (FXS). Investigators hypothesize that minocycline and lo...
The proposed study would evaluate the benefits of riluzole add-on treatment to patients with schizophrenia who are already receiving medications, but still experience symptoms. Neuroprotec...
The goal of this study was to assess the effectiveness of risperidone monoantipsychotic therapy targeting irritability in patients with Fragile X syndrome (FXS) in a naturalistic outpatient clinical s...
Fragile X syndrome (FXS), a leading cause of inherited intellectual disability, most commonly results from an expansion of the CGG trinucleotide repeat in the fragile X mental retardation 1 (FMR1) gen...
Premutation in the FMR1 gene occur in the general population with an estimated prevalence 1 in 130-260 females and 1 in 250-810 males. Carriers of premutation are at risk of development of spectrum of...

A general understanding exists that inhibition of glutamatergic neurotransmission in the basolateral amygdala (BLA) impairs fear extinction in rodents. Surprisingly, we recently found that systemic ad...
Specific loci that show up during KARYOTYPING as a gap (an uncondensed stretch in closer views) on a CHROMATID arm after culturing cells under specific conditions. These sites are associated with an increase in CHROMOSOME FRAGILITY. They are classified as common or rare, and by the specific culture conditions under which they develop. Fragile site loci are named by the letters "FRA" followed by a designation for the specific chromosome, and a letter which refers to which fragile site of that chromosome (e.g. FRAXA refers to fragile site A on the X chromosome. It is a rare, folic acid-sensitive fragile site associated with FRAGILE X SYNDROME.)
A RNA-binding protein that is found predominately in the CYTOPLASM. It helps regulate GENETIC TRANSLATION in NEURONS and is absent or under-expressed in FRAGILE X SYNDROME.
An increased number of contiguous trinucleotide repeats in the DNA sequence from one generation to the next. The presence of these regions is associated with diseases such as FRAGILE X SYNDROME and MYOTONIC DYSTROPHY. Some CHROMOSOME FRAGILE SITES are composed of sequences where trinucleotide repeat expansion occurs.
A glutamate antagonist (RECEPTORS, GLUTAMATE) used as an anticonvulsant (ANTICONVULSANTS) and to prolong the survival of patients with AMYOTROPHIC LATERAL SCLEROSIS.
A condition characterized genotypically by mutation of the distal end of the long arm of the X chromosome (at gene loci FRAXA or FRAXE) and phenotypically by cognitive impairment, hyperactivity, SEIZURES, language delay, and enlargement of the ears, head, and testes. MENTAL RETARDATION occurs in nearly all males and roughly 50% of females with the full mutation of FRAXA. (From Menkes, Textbook of Child Neurology, 5th ed, p226)
Anxiety is caused by stress. It is a natural reaction, and is beneficial in helping us deal with tense situations and pressure. It is deterimental when is becomes an excessive, irrational dread of everyday situations. The most common types of anxiety di...
