Fragile X-associated disorders are a family of inherited disorders caused by expansions in the Fragile X Mental Retardation 1 (FMR1) gene. Premutation expansions of the FMR1 gene confer risk for fragile X-associated primary ovarian insufficiency and fragile X-associated tremor ataxia syndrome, as well as other medical and psychiatric comorbidities. Premutation expansions of the FMR1 gene are common in the general population. However, fragile X-associated disorders are frequently under-recognised and often misdiagnosed.

Fragile X syndrome (FXS) is the second most common inherited cause of intellectual disability (ID), after Down syndrome. The severity of ID in FXS patients varies and depends mainly on the patient's s...
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...
Chromosome fragile sites are a fascinating cytogenetic phenomenon now widely implicated in a slew of human diseases ranging from neurological disorders to cancer. Yet, the paths leading to these revel...
To determine frequency of fragile X associated premature ovarian insufficiency (FXPOI) among Turkish premutation carriers.
Clinical checklists available have been developed to assess the risk of a positive Fragile X syndrome but they include relatively small sample sizes. Therefore, we carried out a meta-analysis that inc...
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...
This study will examine whether individuals with the fragile X genetic premutation are likely to have emotional, social, and memory deficits and how the brain may be involved in these defi...
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...
This study is a controlled trial of metformin in individuals with fragile X syndrome between the ages of 6 and 25 years. Participants will be randomized in a double-blind design to either ...
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.
Event that presented a risk but did not result in a patient harm.
Disorders of verbal and nonverbal communication caused by receptive or expressive LANGUAGE DISORDERS, cognitive dysfunction (e.g., MENTAL RETARDATION), psychiatric conditions, and HEARING DISORDERS.
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
Psychiatry is the study of mental disorders and their diagnosis, management and prevention. Conditions include schizophrenia, severe depression and panic disorders among others. There are pharmaceutical treatments as well as other therapies to help...
