Fragile X syndrome is the most common familial form of mental retardation. This X-linked disorder affects one in every 1000 males and one in every 2000 females. The female carrier rate in the general population is estimated to be 1/600. A fragile site at the distal long arm of the X chromosome (Xq 27.3) is the hallmark cytogenetic feature of the ...

Pediatrics In Review, 2005
AbstractFragile X syndrome, the most common genetic disorder associated with mental retardation is caused by an expansion of the unstable CGG repeat within the FMR1 gene. Although overgrowth is not the main hallmark of this condition, the fragile X syndrome is usually included in the differential diagnosis of children with mental retardation and excess

The fragile X syndrome is characterized by mental handicap, facial dysmorphism and expression of a fragile site at Xq27.3. An expansion of a CGG repeat in the 5' end of the fragile X mental retardation 1 (FMR1) gene results in the absence of the encoded fragile X mental retardation protein, known to play an important role in RNA processing and probably

Fragile X syndrome (FXS) is the leading inherited form of intellectual disability and autism spectrum disorder, and patients can present with severe behavioural alterations, including hyperactivity, impulsivity and anxiety, in addition to poor language development and seizures.

Current Opinion in Pediatrics, 1989
Males who possess the fragile X chromosome, a marker on the end of the X chromosome at position Xq27.3, have a distinct form of mental retardation, which has come to be known as the fragile X [fra(X)] syndrome. This X-linked syndrome is the most common Mendelian form of mental retardation.

Fragile X syndrome is one of the most intriguing genetic conditions now being studied. As the most common inherited form of mental retardation, it has an incidence of approximately 1 in 1000 male infants and boys. Because the cytogenetic diagnosis has only recently been available, many affected boys and female carriers have not yet been identified ...

Despite earlier awareness of the need for pediatricians to recognize and diagnose developmental delay, the average age at diagnosis of fragile X syndrome (FXS) according to a study by Bailey et al,1 published in this issue of Pediatrics , has remained unchanged at 35 to 37 months of age.

Fragile X syndrome is a leading cause of mental retardation worldwide, with an incidence of approximately one case in 2000 live births. It is amongst the most common of human genetic diseases, and was the first to be associated with an unstable trinucleotide (CGG) repeat sequence.

Hyperactivity and the Fragile X Syndrome
Journal of Abnormal Child Psychology, 1991Workers who have claimed an association between Fragile X [fra(x)] Syndrome and Hyperactivity and aggressive behavior have done so despite the lack of controlled studies using standard diagnostic criteria. Accordingly, we provided a controlled test of the hypothesis that individuals with the fra(x) Syndrome are more hyperactive and have more symptoms ...

Autistic spectrum disorders (ASDs) are characterized by impairments in language, social skills, and repetitive behaviors, often accompanied by intellectual disability. Advances in the genetics of ASDs are providing new glimpses into the underlying neurobiological mechanisms disrupted in these conditions.
