Fragile X syndrome (FXS) is a monogenic disorder that is caused by the absence of FMR1 protein (FMRP). FXS serves as an excellent model disorder for studies investigating disturbed molecular mechanisms and synapse function underlying cognitive impairment, autism, and behavioral disturbance. Abnormalities in dendritic spines and synaptic transmission in

A Family with Fragile-X Syndrome
The Journal of Nervous and Mental Disease, 1984A family with fragile-X syndrome is reported. One sibling has atypical pervasive developmental disorder and moderate mental retardation. A second sibling has Tourette's syndrome, moderate mental retardation, seizure disorder, and autism. A third sibling has attention deficit disorder, moderate mental retardation, and developmental language disorder ...

Prevalence of fragile X syndrome
American Journal of Medical Genetics Part A, 1996The much-quoted prevalence figure of 1:1,000 males for fragile X syndrome is an overestimate in a mixed ethnic population. A reexamination of the individuals from whom those data were derived using molecular diagnostic techniques demonstrates a more realistic figure of 1:4,000 males.

1. Fragile X syndrome is defined by the combination of a characteristic phenotype, cognitive impairment, the presence of a fragile site (gap) detectable in folate-free culture medium on Xq27.3 called FRA X A, and transcriptional inhibition, through overmethylation, of an mRNA protein-binding gene called FMR-1. 2. It is inherited in an atypical X-linked

Fragile X syndrome and fragile X-associated tremor ataxia syndrome
2018Fragile X-associated disorders encompass several conditions, which are caused by expansion mutations in the fragile X mental retardation 1 (FMR1) gene. Fragile X syndrome is the most common inherited etiology of intellectual disability and results from a full mutation or >200 CGG repeats in FMR1.

The Pathophysiology of Fragile X Syndrome
Annual Review of Genomics and Human Genetics, 2007Fragile X syndrome is the most common form of inherited mental retardation. The disorder is mainly caused by the expansion of the trinucleotide sequence CGG located in the 5′ UTR of the FMR1 gene on the X chromosome. The abnormal expansion of this triplet leads to hypermethylation and consequent silencing of the FMR1 gene.

Autism and the fragile X syndrome
American Journal of Psychiatry, 1986The fragile X chromosome is an important factor in inherited mental retardation in males. It has also been reported that infantile autism is associated with fragile X. Recently, an article reported an examination of a small sample of autistic children in whom the fragile X chromosome was not found.

Fragile X syndrome and the amygdala
Current Opinion in Neurobiology, 2011Fragile X syndrome (FXS) is the most commonly inherited form of mental impairment and autism. Current understanding of the molecular and cellular mechanisms underlying FXS symptoms is derived mainly from studies on the hippocampus and cortex. However, FXS is also associated with strong emotional symptoms, which are likely to involve changes in the ...

The fragile X syndrome include clinical features macroorchidism, ear large, prognathism, elongated facies, speech dysfunction, mental retardation and mitral valve prolapse. The interest for this syndrome is linked to the antibiotic prophylaxis for bacterial secondary endocarditis and bacteremia.

Of mice and the fragile X syndrome
Trends in Genetics, 2003Fragile X syndrome is the most common cause of inherited mental retardation, and recently a number of mouse models have been generated to study the condition. Knockout of the gene associated with fragile X, Fmr1, results in mild, but consistent abnormalities, analogous to the clinical and pathological symptoms observed in human patients.
