Genomic Unity® Comprehensive Ataxia Analysis
Test Description
Test Code – NR002
Ataxias are a group of neurological conditions most often related to degeneration of the cerebellum, the part of the brain that coordinates movement. Ataxia can affect different parts of the body, speech, eye movements, and balance.
Genomic Unity® Comprehensive Ataxia Analysis uses a whole genome sequencing platform to diagnose genetic causes of ataxia in 52 genes. This test includes additional analyses beyond the repeat expansion genes on the Genomic Unity® Ataxia Repeat Expansion Analysis.
When to order
Order this test when clinical symptoms are consistent with ataxia and you’d like to test a broader set of genes than just the repeat expansion loci. You also have the option to reflex up to Genomic Unity® Exome Analysis or Genomic Unity® Exome Plus Analysis if targeted analysis is non-diagnostic.
Included Analyses
- Sequence analysis of ataxia-associated genes (single nucleotide variants, deletions, insertions, and characterized intronic variants)
- Copy number variant analysis of ataxia-associated genes (duplications/deletions, mobile element insertions, and inversions)
- Short tandem repeat (STR) analysis of the ATN1, ATXN1, ATXN2, ATXN3, ATXN7, ATXN8OS, ATXN10, CACNA1A, FMR1, FXN, NOP56, PPP2R2B, and TBP genes
Optionally includes:
