How do I know if I have Friedreich Ataxia?

Friedreich Ataxia is a rare, inherited neurodegenerative disorder typically diagnosed through genetic testing that confirms an expansion of the FXN gene. If you are concerned, look for progressive signs of unsteadiness (ataxia), muscle weakness, and impaired coordination, and consult a neurologist to request a specific molecular genetic test for Friedreich Ataxia.

What are the early signs of Friedreich Ataxia?

The hallmark of Friedreich Ataxia is progressive ataxia, which often presents as difficulty with balance or a "clumsy" gait, typically beginning in childhood or adolescence (most commonly between ages 5 and 15). Early indicators that should prompt medical investigation include a noticeable decline in physical coordination, frequent tripping, or a widening of your stance when standing. Because Friedreich Ataxia is a multisystem condition, early signs may also include subtle changes in speech (dysarthria) or a lack of deep tendon reflexes during a routine physical exam.

How do I differentiate normal variation from symptoms?

It is natural to worry about occasional clumsiness, but Friedreich Ataxia follows a distinct pattern of progression rather than isolated incidents. While normal variation may involve occasional trips or fatigue, the symptoms of Friedreich Ataxia are persistent, worsen over time, and usually involve a combination of neurological and physical findings. Unlike benign coordination issues, this condition often presents with a combination of the following indicators:

• Progressive difficulty with balance and walking (ataxia)


• Loss of sensation in the extremities (sensory neuropathy)


• Foot deformities, such as high arches or hammer toes


• Heart involvement (hypertrophic cardiomyopathy) often detected via EKG


• Scoliosis or curvature of the spine

When should I see a doctor and what tests should I request?

If you notice a consistent decline in your motor skills or balance, you should schedule an appointment with a neurologist. When speaking with your physician, be specific about the timeline of your symptoms and mention any family history of movement disorders. To investigate Friedreich Ataxia, the gold standard is a molecular genetic blood test that looks for the expansion of the GAA triplet repeat in the FXN gene. This test is definitive and is the primary way clinicians confirm the diagnosis.

How do I advocate for myself if my concerns are dismissed?

If a primary care provider dismisses your symptoms, you have the right to request a referral to a neurologist or a clinical geneticist. It can be helpful to keep a "symptom diary" documenting how your balance or coordination has changed over the past six months. You may also find comfort and guidance by connecting with the 105 community members on DiseaseMaps.org who have navigated the diagnostic journey for Friedreich Ataxia. Having a documented history of your concerns makes it easier for specialists to understand the necessity of genetic testing.

Next steps

• Consult a neurologist or clinical geneticist to discuss genetic testing for the FXN gene.


• Request a referral for a cardiac evaluation, as early detection of heart involvement is vital in Friedreich Ataxia.


• Join a patient support group or the DiseaseMaps community to share experiences with others living with this condition.


• Prepare a detailed list of symptoms and a family health history before your appointment.
