Overview
The purpose of mitochondrial genome sequencing data analysis is to identify genetic variations in the mitochondrial DNA that may be responsible for unexplained neurological, muscular, or metabolic symptoms. This test aids in confirming a clinical diagnosis of mitochondrial disease, guiding treatment decisions, assessing recurrence risks, and enabling family planning. It is particularly useful when other diagnostic tests have been inconclusive.

Test Parameters & Specifications
Sample Stability
- Hemolyzed blood sample
- Insufficient sample volume
- Sample not labeled correctly
- Sample received after prolonged storage at room temperature
Understanding Your Results
Positive
A pathogenic variant was identified. This confirms the diagnosis of a mitochondrial disorder. Genetic counseling is recommended.
Action: Discuss treatment options and family planning with your physician.
Negative
No pathogenic variants were detected. This does not rule out a mitochondrial disorder, as nuclear gene mutations or low-level heteroplasmy may be present.
Action: Consider further testing such as nuclear gene panel or biochemical assays.
Variant of Uncertain Significance (VUS)
A genetic variant was found, but its clinical significance is unknown. Further family studies or functional assays may be needed.
Action: Consult with a genetic counselor for personalized risk assessment.
If you experience symptoms such as persistent fatigue, muscle weakness, seizures, or vision/hearing loss, consult a neurologist or geneticist. Early diagnosis can improve management and quality of life.
Limitations
- ⚠This test does not detect nuclear gene mutations that affect mitochondrial function
- ⚠Low-level heteroplasmy may not be detected
- ⚠Variants of uncertain significance may be reported
- ⚠Not a substitute for clinical diagnosis
Risks & Considerations
- ●Minimal risk of bruising or infection at the blood draw site
- ●Psychological impact of receiving genetic results
- ●Potential for incidental findings
Interfering Factors
- ●Poor DNA quality or quantity
- ●Contamination with nuclear DNA
- ●Heteroplasmy levels below detection limit
- ●Recent blood transfusion (for blood samples)
