Ataxias are a group of neurological conditions most often related to degeneration of the cerebellum, the area of the brain responsible for coordinating movement.

Genomic Unity® FXN Analysis is an effective test for Friedreich’s ataxia. 

For comprehensive coverage of ataxia-related genes in addition to FXN, consider Genomic Unity® Comprehensive Ataxia Analysis.

Order this test when the patient presents with symptoms of Friedreich's ataxia and you'd like the option to specifically test the FXN gene, keeping the option to reflex up to Genomic Unity® Exome Plus Analysis.

  • Sequencing analysis of the FXN gene
  • Del/dup analysis of the FXN gene
  • Tandem repeat expansion analysis of the FXN gene

Optionally includes:

  • Reflex to Genomic Unity® Exome Plus Analysis
