Genomic Unity® Muscular Dystrophy Analysis
Test Code – NR008
Muscular dystrophies are a group of genetic disorders characterized by progressive muscle degeneration and weakness. The affected muscle groups, age of onset, and additional clinical features are dependent upon the type of disease.
Genomic Unity® Muscular Dystrophy Analysis uses a whole genome sequencing platform to diagnose genetic causes of muscle weakness in 52 genes.
When to order
Order this test when clinical symptoms of muscle weakness are present and consistent with the muscular dystrophies listed below. You also have the option to reflex up to Genomic Unity® Exome Analysis or Genomic Unity® Whole Genome Analysis if targeted analysis is non-diagnostic.
If you strongly suspect your patient of having Duchenne or Becker muscular dystrophy, consider ordering Genomic Unity® DMD Gene Analysis.
For a broader analysis of genes associated with neuromuscular disorders (muscular dystrophies, myopathies, myotonic syndromes, congenital myasthenic syndrome, congenital disorders of glycosylation), consider ordering Genomic Unity® Neuromuscular Disorders Analysis.
Notes about testing:
At this time, Genomic Unity® Muscular Dystrophy Analysis does not include analysis of tandem repeat expansions in the PABPN1 gene. This is not an appropriate test if you suspect oculopharyngeal muscular dystrophy.
- Sequence analysis of muscular dystrophy-associated genes (single nucleotide variants, deletions, insertions, and characterized intronic variants)
- Copy number variant analysis of muscular dystrophy-associated genes (duplications/deletions, mobile element insertions, and inversions)
This test covers many disorders including:
- Becker muscular dystrophy
- Duchenne muscular dystrophy
- Emery-Dreifuss muscular dystrophies
- Limb-Girdle muscular dystrophies
- Muscular dystrophy-dystroglycanopathies
- Rigid spine muscular dystrophy
- Ullrich congenital muscular dystrophy
- Walker-Warburg syndrome
- Other congenital muscular dystrophies
