Fragile X Associated Disorders

Fragile X Syndrome

Fragile X Syndrome (FXS) is a genetic disorder caused by a mutation (a change in the DNA structure) in the X chromosome. It is the most common known cause of inherited developmental disability worldwide. One in 3,600 males and one in 4-6,000 females are affected. One in 150 females carry the premutation and will pass the gene on to 50% of their offspring, male or female, any of whom may be affected.


Fragile X-associated tremor/ataxia syndrome (FXTAS), a condition which affects balance, tremor and memory in some older male gene carriers.


Fragile X-associated primary ovarian insufficiency (FXPOI), a problem with ovarian function which can lead to infertility and early menopause in some female gene carriers.
