Test Details
Fragile X Tremor/Ataxia Syndrome (FXTAS) is a genetic disorder that primarily affects older males who carry a premutation in the FMR1 gene. The premutation is a genetic variant of the FMR1 gene that is characterized by an expansion of a specific DNA sequence. FXTAS is characterized by progressive tremors, ataxia (loss of muscle coordination), cognitive decline, and other neurological symptoms.
To diagnose FXTAS, several tests may be conducted:
- Genetic testing: This is the primary test used to diagnose FXTAS. It involves analyzing the FMR1 gene to identify the presence of a premutation or a full mutation. A blood sample or a cheek swab is usually taken for genetic testing.
- Fragile X DNA test: This test specifically looks for the expansion of the CGG repeat sequence in the FMR1 gene. A larger number of CGG repeats indicates a premutation or full mutation.
- Family history and clinical evaluation: The doctor will inquire about the patient’s family history of Fragile X syndrome or related disorders. A thorough clinical evaluation will also be conducted to assess the presence of symptoms associated with FXTAS, such as tremors, ataxia, cognitive decline, and psychiatric symptoms.
- Neurological examination: A neurological examination will be performed to assess motor skills, coordination, reflexes, and other neurological functions.
- Magnetic Resonance Imaging (MRI) scan: An MRI scan may be recommended to evaluate brain structure and detect any characteristic findings associated with FXTAS, such as white matter lesions or brain atrophy.
It is important to note that FXTAS can have overlapping symptoms with other neurodegenerative disorders, so a comprehensive evaluation is necessary to make an accurate diagnosis. A team of healthcare professionals, including geneticists, neurologists, and genetic counselors, may be involved in the diagnostic process.
