Genetic counseling for FXTAS and FMR1-associated disorders

Abstract

Since its identification in 2001, awareness of fragile X-associated tremor/ataxia syndrome (FXTAS) has increased. The number of patients and families impacted by the condition continues to grow. Families with and without a history of fragile X syndrome (FXS) are impacted. Patients are usually identified based on their neurological findings such as intentional tremor, balance and gait difficulties, cognitive impairment, and brain MRI abnormalities.
