Mitochondrial disease

Simplified testing for a challenging diagnosis

The complexity of mitochondrial disease and the amount of clinical and laboratory data required for each patient necessitates a streamlined testing approach and expertise to synthesize and integrate test results. We recommend sequencing the entire mitochondrial genome and/or performing a comprehensive nuclear gene panel and offer four molecular test options, which can complement radiological and histological evaluations, to confirm a diagnosis and identify a specific mitochondrial syndrome.

Mitochondrial disease

Our testing employs highly sensitive droplet digital polymerase chain reaction (ddPCR) technology to detect mitochondrial DNA deletions and duplications. This is the only method available to enable absolute, rather than relative/indirect, quantification of heteroplasmy and significantly reduces the risk of false-negative and false-positive results. To successfully capture copy number variants that fall outside of normal breakpoints typically detected by other laboratory tests, our assay uses six different primer sets. This approach has enabled successful diagnoses in patients with previous false-positive or false-negative results from other labs.

Biochemical testing

The diagnostic process for mitochondrial disease may begin with a set of biochemical tests that, when abnormal, can be indicative of a metabolic disorder. Correlating biochemical laboratory results with the clinical presentation and other test results can further confirm suspicion of mitochondrial disease.
