What is FA ataxia?
Friedreich ataxia (also called FA) is a rare inherited disease that causes progressive nervous system damage and movement problems. It usually begins in childhood and leads to impaired muscle coordination (ataxia) that worsens over time.
What is the life expectancy of someone with Friedreich’s ataxia?
The symptoms of Friedreich’s ataxia usually get gradually worse over many years. People with the condition tend to have a shorter life expectancy than normal. Many people live until at least their 30s, and some can live into their 60s or beyond.
What is the cause of Friedreich’s ataxia?
Friedreich’s ataxia is an inherited disease. It’s caused by a problem in a gene called FXN. It’s a recessive genetic disorder. This means you need to get a copy of the gene defect from both parents to be affected.
What is the major cause of FA?
What causes FA? FA is a hereditary disease, caused by a defective gene that can be passed down through a family. Mutations in the gene that carries instructions for a protein called frataxin result in diminished energy production in cells, including those of the nervous system and heart.
How serious is ataxia?
Life expectancy is generally shorter than normal for people with hereditary ataxia, although some people can live well into their 50s, 60s or beyond. In more severe cases, the condition can be fatal in childhood or early adulthood. For acquired ataxia, the outlook depends on the underlying cause.
How is FA diagnosed?
How is FA diagnosed? The only conclusive diagnostic test for FA is genetic testing to identify disease-causing mutations in a person’s copies of the FXN gene. Other tests that may aid in its diagnosis include nerve conduction studies, tests of heart function, urinary and blood tests, and MRI scans.
Does ataxia affect memory?
The cerebellum plays a role in some forms of thinking. Patients with cerebellar atrophy may have impaired recall of newly learned information or difficulty with “executive functions” such as making plans and keeping thoughts in proper sequence.
Are you born with ataxia?
Hereditary ataxias Some types of ataxia and some conditions that cause ataxia are hereditary. If you have one of these conditions, you were born with a defect in a certain gene that makes abnormal proteins.
What are the early signs of ataxia?
Typically the most common symptoms of ataxia are listed below:
- Balance and coordination are affected first.
- Poor coordination of hands, arms, and legs.
- Slurring of speech.
- Wide-based gait (manner of walking)
- Difficulty with writing and eating.
- Slow eye movements.
What is Frederick disease?
Friedreich’s ataxia is an inherited disorder that affects some of the body’s nerves. It is caused by a gene defect that is inherited from both parents. Symptoms often begin in late childhood and can include trouble walking, fatigue, changes in sensation, and slowed speech. These tend to get worse over time.
Does ataxia affect the brain?
Cerebellum and brainstem A sign of an underlying condition, ataxia can affect various movements and create difficulties with speech, eye movement and swallowing. Persistent ataxia usually results from damage to the part of your brain that controls muscle coordination (cerebellum).
Is FA an autoimmune disease?
The condition is caused by mutations in the FXN gene on chromosome 9, which makes a protein called frataxin. In FRDA, cells produce less frataxin….

When does the disease of Friedreich ataxia begin?
What is Friedreich ataxia? Friedreich ataxia (also called FA) is a rare inherited disease that causes progressive nervous system damage and movement problems. It usually begins in childhood and leads to impaired muscle coordination (ataxia) that worsens over time.
Which is the most common form of ataxia?
Friedreich’s ataxia (FA) is a rare, progressive neurogenetic condition found in approximately 1 in 50,000 people worldwide. While FA is relatively rare, it is the most common form of inherited ataxia.
How old do you have to be to have ataxia?
Onset is typically between 10 and 15 years of age, but FA has been diagnosed in people from ages 2 to 50. FA progresses slowly, and the sequence and severity of its progression is highly variable. Although there’s no cure for FA as yet, treatments exist for cardiac symptoms, and there are ways to manage ataxia and muscle weakness.
How many people are affected by hereditary ataxia?
FA affects about one in 50,000 people worldwide, making it the most common in a group of related disorders called hereditary ataxias. It shouldn’t be confused with a group of diseases known as autosomal dominant spinocerebellar ataxias. What are the symptoms of FA?
