Mitochondrial Genome Sequencing: Fast & Precise mtDNA & Heteroplasmy Test
Clinical Overview & Diagnostic Indications
First of all, Mitochondrial Genome Sequencing is the specialized genomic test that sequences the complete 16,569 base pair circular mitochondrial DNA (mtDNA). Essentially, ultra-deep Next-Generation Sequencing (>10,000X coverage) profiles all 37 mitochondrial genes, structural deletions, and low-level heteroplasmy down to 1% sensitivity. Consequently, pediatricians, neurologists, and geneticists diagnose complex mitochondrial encephalomyopathies with 99.9% precision.
Furthermore, book your Mitochondrial Genome Sequencing at Henotic Diagnostics for comprehensive diagnostic clarity. In addition, our accredited genomic laboratory operates 24/7 with convenient home sample collection services.

Overview of Mitochondrial Genome Sequencing
To begin with, mtDNA Sequencing analyzes the maternally inherited 16,569 base pair circular genome inside human cellular mitochondria. At the same time, experts at Henotic Diagnostics perform long-range PCR enrichment followed by high-depth Next-Generation Sequencing to evaluate mitochondrial DNA integrity.

What Does Mitochondrial Genome Sequencing Evaluate?
Specifically, mtDNA Sequencing screens all 37 mtDNA genes encoding 13 oxidative phosphorylation proteins, 22 transfer RNAs (tRNAs), and 2 ribosomal RNAs (rRNAs). Consequently, bioinformatic algorithms measure heteroplasmy—the precise percentage of mutant versus wild-type mitochondrial DNA copies within cells. Furthermore, ultra-deep sequencing detects single nucleotide variants and large structural deletions. As a result, physicians diagnose mitochondrial myopathies accurately. In fact, to review mitochondrial disorder guidelines, consult the NIH NINDS Mitochondrial Myopathies guide.

What is Mitochondrial Genome Sequencing?
In general, human cells contain hundreds of mitochondria, each carrying multiple circular mtDNA copies. Essentially, pathogenic mutations often co-exist with normal mtDNA (heteroplasmy), requiring ultra-deep sequencing (>10,000X depth) to detect low-abundance mutant copies. Therefore, long-range PCR amplifies intact circular mtDNA before sequencing. Additionally, to read about mitochondrial DNA genetics research, examine the Nature Reviews Genetics journal.
Additionally, high-throughput NGS platforms sequence circular 16.5kb mtDNA with 99.9% heteroplasmy accuracy
What Does Mitochondrial Genome Sequencing Check?
Overall, clinical Mitochondrial Genome profiling evaluates key diagnostic categories:
Key Mitochondrial Genes & Heteroplasmy Targets Evaluated
In addition, bioinformatic software maps 16.5kb circular mtDNA, heteroplasmy load, and deletion breakpoints
When Is Mitochondrial Genome Sequencing Recommended?
For example, neurologists, pediatricians, and ophthalmologists order mtDNA Sequencing for patients presenting with multi-system symptoms. In particular, testing is recommended for unexplained muscle weakness, exercise intolerance, stroke-like episodes, optic atrophy (LHON), sensorineural hearing loss, and lactic acidosis. Moreover, it is used to evaluate maternal risk for inherited mitochondrial disorders. In addition, to review ACMG diagnostic standards, examine the ACMG Medical Genetics guidelines.
Moreover, expert clinical consultation translates mtDNA heteroplasmy data into targeted metabolic management
Clinical Superiority: Ultra-Deep NGS vs. Standard Sanger mtDNA Testing
Ideally, clinicians should choose ultra-deep NGS for mtDNA Sequencing because older Sanger sequencing fails to detect heteroplasmy below 15-20%. In addition, NGS at >10,000X coverage reliably quantifies low-abundance pathogenic variants in blood and tissue. Indeed, to review global inherited metabolic disease facts, consult the WHO Inherited Metabolic Disorders Fact Sheet.

Comparison: Mitochondrial Genome (mtDNA) vs. Nuclear Exome (WES)
On one hand, Nuclear Exome Sequencing (WES) analyzes the ~20,000 genes encoded in nuclear chromosomes, whereas mtDNA Sequencing profiles the 37 genes encoded in circular mitochondrial DNA. Consequently, both tests are complementary for mitochondrial disease diagnosis. In fact, review the PubMed Clinical Mitochondrial Sequencing Review.
| Feature | Mitochondrial Genome (mtDNA) | Nuclear Whole Exome (WES) |
|---|---|---|
| Genome Origin | First, 16.5kb circular mitochondrial DNA. | However, 3 billion bp nuclear DNA. |
| Inheritance Pattern | Second, 100% maternal inheritance. | In contrast, biparental Mendelian inheritance. |
| Heteroplasmy Quantification | In addition, accurate heteroplasmy (1-100%). | Meanwhile, heterozygous / homozygous. |
| Associated Diseases | Finally, MELAS, MERRF, Leigh, LHON, KSS. | Likewise, Mendelian nuclear genetic disorders. |
