Genomic Unity® Neuromuscular Disorders Analysis
Test Description
Test Code – NR007
Neuromuscular disorders encompass a wide spectrum of nerve-related diseases and conditions that affect the body’s muscles. People often experience progressive muscle weakness and atrophy due to disrupted communication between the nervous system and the muscles they control. Symptoms may include twitching or uncontrolled movements, cramps, pain, muscle weakness or rigidity, as well as difficulty with coordinated movements.
Genomic Unity® Neuromuscular Disorders Analysis uses a whole genome sequencing platform to diagnose genetic causes of muscle weakness in 126 genes.
When to Order
Order this test when clinical symptoms are consistent with muscular dystrophy, myotonic dystrophy types I or II (DM1 or DM2), congenital myopathy, or congenital myasthenic syndrome. 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 neuromuscular-associated genes (single nucleotide variants, deletions, insertions, and characterized intronic variants).
- Copy number variant analysis of neuromuscular-associated genes (deletions/duplications, mobile element insertions, and inversions).
- Short tandem repeat (STR) analysis of the CNBP and DMPK genes.
Optionally includes:
Included Genes
Note: The NEB gene is not fully covered by this test, therefore not all pathogenic variants may be detected. The NEB and TTN genes contain regions that are non-unique, therefore not all variants can be assigned to the correct location, limiting interpretation. The false negative rate has not been determined for CNBP.
Disorders
This test covers many disorders including:
- Becker and Duchenne muscular dystrophy
- Myotonic dystrophy type I
- Myotonic dystrophy type II
- Congenital myopathy syndromes
- Congenital myasthenic syndromes
