Genomic Unity® Neuropathies Analysis
Test Description
Test Code – NR009
Hereditary neuropathies are a group of disorders that affect the peripheral nervous system and are characterized by progressive muscle weakness, atrophy, and loss of sensation. Hereditary neuropathies can be motor, sensory, motor and sensory, or sensory and autonomic.
Genomic Unity® Neuropathies Analysis uses a whole genome sequencing backbone to diagnose genetic causes of neuropathy in 103 genes.
When to order
Order this test when clinical symptoms are consistent with inherited neuropathy. 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 neuropathy-associated genes (single nucleotide variants, deletions, insertions, and characterized intronic variants).
- Copy number variant analysis of neuropathy-associated genes (duplications/deletions, mobile element insertions, and inversions).
- Short tandem repeat (STR) analysis of the GIPC1, LRP12, RFC1, VWA1 and ZFHX3 genes. (Learn more)
