Fragile X syndrome Description Fragile X syndrome is a genetic condition that causes a range of developmental problems including learning disabilities and cognitive impairment Usually males are more severely affected by this disorder than females Affected individuals usually have delayed development of speech and language by age 2
What is the fragile X syndrome?
The Fragile X syndrome (FXS) was first described by Dr. Martin and Dr. Bell in 1943, in families with several patients affected by sex-linked mental disability. This disorder is the most common cause of inherited mental disability. The prevalence of the Fragile X syndrome has been established at 1 in 2,500 males and 1 in 4000 females.
What is fragile X-associated tremor/ataxia syndrome?
Fragile X-associated tremor/ataxia syndrome. Men, and some women, with an FMR1 gene premutation are at increased risk of developing a disorder known as fragile X-associated tremor/ataxia syndrome (FXTAS).
Who should be considered for Fragile X testing?
Any child with signs of developmental delay of speech, language, or motor development with no known cause should be considered for fragile X testing, especially if there is a family history of the condition. Behavioral and developmental problems may indicate fragile X syndrome, particularly if there is a family history of mental retardation.
Is fragile X syndrome associated with a disruption of the endocannabinoid system?
Recent studies suggest that Fragile X Syndrome (FXS) and other neuropsychiatric conditions may be associated with a disruption in the endocannabinoid (EC) system. (14.)
