Fragile X Disorders
Fragile X-associated Disorders are a family of inherited conditions caused by alterations (expansions) in the FMR1 gene on the X chromosome.
These include Fragile X syndrome, Fragile X-associated Tremor Ataxia syndrome (FXTAS), Fragile X-associated Primary Ovarian Insufficiency (FXPOI) and the newer term Fragile X-associated Neuropsychiatric Disorders (FXAND).
Fragile X-associated disorders are considered to be frequently under-recognised and often misdiagnosed.(1)
