Fragile X-associated tremor ataxia syndrome

Synopsis

Fragile X-associated tremor ataxia syndrome (FXTAS) is a hereditary (X-linked dominant) neurodegenerative disorder. The disorder results in intention tremor and ataxia. Tremor typically precedes ataxia by a few years. Other associated symptoms include mild cognitive impairment, dysautonomia, parkinsonism, mood instability, and/or peripheral neuropathy.

Onset of disease is typically after age 50. It affects men more frequently and more severely than women. In women, it may be associated with premature ovarian failure resulting in early menopause, hypothyroidism, or fibromyalgia. Progression is variable, ranging from gradual to rapid. There is no cure, and management is symptomatic.

For more information, see OMIM.
