Fragile X syndrome (FXS) is caused by a triplet repeat expansion on the FMR1 gene. Individuals with >200 repeats have FXS, while individuals between 45-54 and 55- 200 repeats have the FMR1 intermediate allele and premutation, respectively. FXS is characterized by autism and intellectual disability while the premutation is associated with fragile X-associated tremor/ataxia syndrome (FXTAS) and fragile X-associated primary ovarian insufficiency (FXPOI). However, recent research shows that the premutation may be associated with psychiatric manifestations. Currently, there are no established clinical features associated with the intermediate allele. This study sought to 1) study knowledge regarding FXTAS, FXPOI, as well …
