Question 3

What gene and chromosome are affected in Friedreich’s ataxia?

Accepted Answer

The disorder is linked to mutations in the FXN gene, located on chromosome 9.

Question 4

When does Friedreich’s ataxia usually appear?

Accepted Answer

Symptoms typically begin in childhood or adolescence, though onset can occasionally occur in adulthood.

Question 5

What are the first signs or symptoms of Friedreich’s ataxia?

Question 6

Is Friedreich’s ataxia inherited?

Accepted Answer

Yes. It follows an autosomal recessive pattern, meaning both copies of the FXN gene must have mutations for the condition to develop.

Question 7

How is Friedreich’s ataxia diagnosed?

Accepted Answer

Diagnosis involves a combination of neurological exams, genetic testing, and sometimes imaging or nerve conduction studies to confirm the condition.

Question 8

What is the life expectancy of someone with Friedreich’s ataxia?

Accepted Answer

Life expectancy varies, but many people with FA live into adulthood. Complications, especially heart disease, can affect longevity.

Question 9

Is there a treatment or cure for Friedreich’s ataxia?

Accepted Answer

There is no cure currently. Treatment focuses on managing symptoms through physical therapy, cardiac care, and assistive devices. Clinical trials for potential therapies are ongoing.

Question 10

Can Friedreich’s ataxia affect the heart or cause diabetes?

Accepted Answer

Yes. Many individuals develop hypertrophic cardiomyopathy, and approximately 10–25% may develop diabetes or insulin resistance as the disease progresses.
