Test Description
Genomic Unity® Comprehensive Mitochondrial 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 mitochondrial genome analysis combined with analysis of 336 nuclear genes associated with mitochondrial disorders.
Genomic Unity® Comprehensive Mitochondrial Disorders Analysis provides a single, unified clinical report that replaces a battery of tests including: multiplex ligation dependent probe amplification (MLPA) and single gene or targeted gene panel testing of nuclear genes plus eliminates the need to order separate testing for mitochondrial genes.
When to Order
Order this test when clinical symptoms affect multiple organ systems and are suggestive of a mitochondrial disorder.

Methods and Limitations
Genomic Unity® Comprehensive Mitochondrial Disorders Analysis uses a PCR-free whole genome sequencing (WGS) platform paired with our Genomic Intelligence® analytical software.
SNVs:
99.9% sensitivity
100% specificity
99.8% positive predictive value
Structural variants:
96% clinical sensitivity
Mitochondrial variants:
Heteroplasmy is not reported for large deletions and duplications are not detected. The false negative rate for mitochondrial large deletions has not been determined.
Test limitations:
The NDUFB11, PRODH and SLC6A8 genes are not fully covered by this test, therefore not all pathogenic variants may be detected. The PRODH and TMLHE genes contain regions that are non-unique, therefore not all variants can be assigned to the correct location, limiting interpretation.
