Genomic Unity® FXN Analysis
Genomic Unity® FXN Analysis uses a whole genome sequencing platform to diagnose genetic causes of Friedreich ataxia in the FXN gene.
When to Order
Order this test when the patient presents with symptoms of impaired muscle coordination consistent with Friedreich ataxia and you’d like the option to reflex up to Genomic Unity® Exome Analysis or Genomic Unity® Exome Plus Analysis
For a broader analysis of genes associated with ataxia, such as spinocerebellar ataxias, episodic ataxias, and Machado-Joseph disease, you may want to consider Genomic UnityⓇ Ataxia Repeat Analysis or Genomic UnityⓇ Comprehensive Ataxia Analysis.
- Sequence analysis of FXN (single nucleotide variants, deletions/insertions, and characterized intronic variants)
- Copy number variant analysis of FXN (duplications/deletions, mobile element insertions, and inversions)
- Short tandem repeat analysis of FXN
This test covers the following disorder:
- Friedreich ataxia
Short tandem repeats:
Due to the variable nature of repetitive sequences and sequence-specific differences in detection and repeat evaluation, orthogonal confirmation is performed on a case-by-case basis. Reportable pathogenic or intermediate repeat expansions may be reported with or without repeat count.
