Genetics Home Reference:22 Fragile X-associated tremor/ataxia syndrome (FXTAS) is characterized by problems with movement and thinking ability (cognition). FXTAS is a late-onset disorder, usually occurring after age 50, and its signs and symptoms worsen with age. This condition affects males more frequently and severely than females. Affected individuals have areas of damage in the part of the brain that controls movement (the cerebellum) and in a type of brain tissue known as white matter, which can be seen with magnetic resonance imaging (MRI). This damage leads to the movement problems and other impairments associated with FXTAS.

MalaCards: Fragile X-Associated Tremor/ataxia Syndrome, also known as fragile x tremor/ataxia syndrome, is related to fragile x syndrome and mental retardation, and has symptoms including myalgia/muscular pain, impotence/painful erection/priapism/erection troubles and troubles of memory/amnesia/hypermnesia. An important gene associated with Fragile X-Associated Tremor/ataxia Syndrome is FMR1 (fragile X mental retardation 1). Affiliated tissues include brain, cerebellum and pons.
