Test Overview & Methodology

Clinical Rationale

The NARS2 gene encodes the mitochondrial asparaginyl-tRNA synthetase, essential for mitochondrial protein synthesis. Pathogenic variants cause Combined Oxidative Phosphorylation Deficiency Type 24 (COXPD24), an autosomal recessive disorder presenting with severe neonatal lactic acidosis, hypertrophic cardiomyopathy, encephalopathy, and early mortality. This targeted NGS assay provides definitive molecular diagnosis to guide reproductive counselling and management planning.

Methodology

Next‑Generation Sequencing (NGS) on the Illumina platform with >100x average coverage across all coding exons and flanking splice junctions of the NARS2 gene. All clinically significant variants are confirmed via Sanger sequencing. Bioinformatics analysis adheres to ACMG/AMP 2015 guidelines with ClinVar and gnomAD population frequency filters.

Feature Our Test (COXPD24 NGS) Closest Alternative (Mitochondrial Panel)
Precision 99.9% analytical sensitivity & specificity for NARS2 mutations ~90% – panel lacks full NARS2 coverage
Method NGS with Sanger confirmation of all variants Targeted NGS of 20‑gene mitochondrial panel
Turnaround 3–4 weeks (urgent option 14 days) 6–8 weeks
DHA Accreditation Yes (Facility License 1143) Varies

Physician Insight & Safety Protocols

“As a DHA-licensed Consultant Medical Geneticist, I emphasize that a positive result for a pathogenic NARS2 variant requires correlation with clinical phenotype, biochemical markers including lactate and amino acid profiles, and neuroimaging findings. A negative result does not exclude COXPD24; further functional studies such as mitochondrial respiratory chain enzyme analysis may be indicated. Please continue all prescribed therapies until you discuss findings with your treating specialist.”

Advisory: Medication & Treatment Continuity

Never discontinue prescribed medication without consulting your doctor. Abrupt withdrawal of anticonvulsants, corticosteroids, or metabolic supplements can trigger acute metabolic decompensation in patients with mitochondrial disease. Discuss any changes with your metabolic specialist before proceeding.

Exclusion Criteria & Emergency Red Flags

  • Avoid home collection if patient has an active febrile illness or uncontrolled seizures.
  • Pediatric patients require a legal guardian present during the blood draw.
  • ER Red Flags: Sudden onset of metabolic acidosis, respiratory distress, or loss of consciousness after sample collection — seek immediate emergency care and inform the laboratory.

Patient FAQ & Clinical Guidance

1. What is the standard turnaround time for the NARS2 genetic test, and can I request expedited processing?

The standard turnaround time is 3–4 weeks from sample receipt. A 14‑day urgent processing option is available for critically ill patients upon written request from the referring physician. Our clinical team will prioritise samples with documented metabolic crisis or impending clinical deterioration.

2. Which specialists should be involved in interpreting and actioning the genetic result?

The result must be reviewed collaboratively by a Consultant Medical Geneticist, a Metabolic Specialist, and the referring General Physician. Our service includes a complimentary 15‑minute telephonic consultation with a DHA‑licensed genetic counsellor to bridge the path from variant classification to a personalised care plan.

3. Does this test detect mitochondrial DNA (mtDNA) abnormalities in addition to nuclear gene variants?

No, this test targets exclusively the nuclear NARS2 gene on chromosome 15. If mitochondrial DNA depletion or multiple deletions are suspected, we recommend parallel sequencing of the mitochondrial genome and analysis of mtDNA copy number. Our laboratory offers a combined nuclear-mitochondrial panel separate from this single‑gene test.

4. What sample types are accepted, and how should the specimen be collected?

Whole blood collected in EDTA tube (3–5 mL) is the preferred specimen. Extracted DNA (>2 µg at >50 ng/µL) or dried blood spots on FTA cards are also accepted. All samples must be transported at 2–8°C via ISO‑certified cold‑chain courier. Our VIP phlebotomy team can collect at your home between 8 AM and 11 PM daily.

5. Is pre-test genetic counselling mandatory before this test can be performed?

Yes, a mandatory pre‑test genetic counselling session (in‑person or via telehealth) is required to document a three‑generation pedigree, discuss inheritance patterns, potential outcomes, and obtain written informed consent in accordance with Federal Decree-Law No. 4 of 2016 on Medical Liability.
