Genomic Unity® Neuropathies Analysis

NR009

Genomic Unity® Neuropathies Analysis is a diagnostic test designed to identify genetic variants that cause neuropathy.

Test Description

Genomic Unity® Neuropathies 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 103 genes associated with neuropathies.

Genomic Unity® Neuropathies 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 inherited neuropathy.

Methods and Limitations

Genomic Unity® Neuropathies 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 IFN2 gene is not fully covered by this test, therefore not all pathogenic variants may be detected.
