What Is Mitochondrial DNA Sequencing?

Mitochondrial DNA (mtDNA) Sequencing is a specialized genetic test that analyzes the DNA found in your mitochondria, the energy-producing parts of your cells. Unlike nuclear DNA, mtDNA is inherited exclusively from the mother, making it crucial for diagnosing inherited mitochondrial diseases, identifying maternal lineage, and conducting genetic research.

This test is used to detect mutations, deletions, or duplications in the mitochondrial genome that can cause a wide range of neurological, muscular, and metabolic disorders.

Procedure Of The Test

1. Sample Collection

   • A small amount of blood, saliva, or tissue is collected in a sterile container.

2. DNA Extraction

   • Mitochondrial DNA is carefully isolated from the sample for analysis.

3. Sequencing

   • The complete mitochondrial genome is sequenced using Next-Generation Sequencing (NGS) technology.

4. Bioinformatics Analysis

   • Genetic data is compared with reference databases to identify any mutations or abnormalities.

5. Reporting

   • A detailed report is generated, including clinically relevant findings and interpretation.

FAQ Section

1. What Conditions Can Mitochondrial DNA Sequencing Detect?
It detects mutations that cause mitochondrial diseases, including Leigh syndrome, MELAS, MERRF, and LHON.

2. How Is This Test Different From Nuclear DNA Sequencing?
mtDNA sequencing analyzes the mitochondrial genome, which is maternally inherited and separate from the DNA in the nucleus.

3. Who Should Get Tested?
Anyone with unexplained metabolic, muscular, or neurological symptoms, or a family history of mitochondrial disease.

4. What Type Of Sample Is Needed?
A blood sample is commonly used, but saliva or tissue samples may also be accepted.

5. How Long Does It Take To Get Results?
The turnaround time is typically 10 to 15 business days.

6. Can I Get This Test In Dubai?
Yes, several specialized genetics laboratories in Dubai offer high-quality mtDNA sequencing.

7. Is It Covered By Insurance?
Coverage varies depending on medical necessity and your provider. It is best to confirm with your clinic or insurer.

Conclusion

Mitochondrial DNA Sequencing is a critical tool in modern genetics, offering unmatched insight into inherited mitochondrial disorders and maternal lineage tracking. Whether you're investigating a rare health condition or conducting medical research, mtDNA testing delivers precision, clarity, and confidence.
