Browse our comprehensive library of diagnostic capabilities. We provide over 200 NABL accredited radiology scans and automated clinical pathology investigations.
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.
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.
Furthermore, comfortable reception lounge providing supportive registration for specialized mitochondrial DNA testing
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.
Furthermore, smooth 99.9% precision with precise mtDNA heteroplasmy insights
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.
13 Protein-Coding Genes (Complex I, III, IV, V): First, screens MT-ND1 to MT-ND6, MT-CYB, MT-CO1 to MT-CO3, MT-ATP6/8.
✓
22 Transfer RNA (tRNA) Genes: Second, uncovers common disease mutations like m.3243A>G (MELAS) and m.8344A>G (MERRF).
✓
Large Single & Multiple Deletions: In addition, detects 1.3kb to 8kb mtDNA deletions linked to Kearns-Sayre syndrome. Review the MITOMAP human mitochondrial genome database.
✓
Quantified Heteroplasmy Levels: Finally, measures mutant mtDNA load from 1% to 100% across tissue samples.
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
Why Ultra-Deep NGS Detects Low-Level Heteroplasmy Down to 1%
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.
