Test Description
Genomic Unity® Neuromuscular Disorders Analysis is a targeted test that uses a whole genome platform to detect all major clinically relevant variant types from a single sample. This targeted test focuses on 133 genes associated with neuromuscular disorders.
Genomic Unity® Neuromuscular Disorders Analysis provides a single, unified clinical report that replaces a battery of tests including: targeted gene panel, single gene analysis and multiplex ligation dependent probe amplification (MLPA), as well as PCR and southern blot tests for short tandem repeat expansions.
When to Order
Order this test when clinical symptoms are consistent with muscular dystrophies, congenital myopathies and congenital myasthenic syndromes.

Methods and Limitations
Genomic Unity® Neuromuscular Disorders Analysis uses a PCR-free whole genome sequencing (WGS) platform paired with our Genomic Intelligence® analytical software.
SNVs:
99.9% sensitivity
99.9% specificity
99.8% positive predictive value
Structural variants:
96% clinical sensitivity
Short tandem repeats:
The false negative rate for repeat expansions has not been determined.
Test limitations:
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.
