Fragile X syndrome(FXS) represents the most common form of inherited mental retardation, and is associated with a highly variable cognitive and behavioral phenotype as well as a characteristic profile of physical features. FXS is an X-linked disorder that affects approximately 1 in 4000 males and ...
Fragile X syndrome is a genetic disorder caused by a mutation in a gene that lies at the tip of the X chromosome. It is linked to autism spectrum disorders. People with fragile X experience a range of symptoms that include cognitive impairment, developmental and speech delays and hyperactivity....
The premutation is associated with no effects, although there is evidence of physical effects—primarily premature menopause and mild outward features of the fragile X syndrome–among premutation carriers. There is much controversy regarding premutation effects on psychological development. The few ...

Fragile X syndrome (FXS), or Martin-Bell syndrome, is a non-Mendelian trinucleotide repeat disorder. FXS is the most prevalent inherited cause of mild-to-severe intellectual disability and the most common monogenic cause of autism spectrum disorder. It accounts for about one-half of cases of X...

Fragile X syndrome (FXS) is caused by epigenetic silencing of the X-linked fragile X messenger ribonucleoprotein 1 (FMR1) gene located on chromosome Xq27.3, which leads to the loss of its protein product, fragile X messenger ribonucleoprotein (FMRP). It
