Pricing Comments

We are happy to accommodate requests for testing single genes in this panel or a subset of these genes. The price will remain the list price. If desired, free reflex testing to remaining genes on panel is available. Alternatively, a single gene or subset of genes can also be ordered via our Custom Panel tool.

An additional 25% charge will be applied to STAT orders. STAT orders are prioritized throughout the testing process.

Click here for costs to reflex to whole PGxome (if original test is on PGxome Sequencing platform).

Click here for costs to reflex to whole PGnome (if original test is on PGnome Sequencing platform).

Turnaround Time

3 weeks on average for standard orders or 2 weeks on average for STAT orders.

Please note: Once the testing process begins, an Estimated Report Date (ERD) range will be displayed in the portal. This is the most accurate prediction of when your report will be complete and may differ from the average TAT published on our website. About 85% of our tests will be reported within or before the ERD range. We will notify you of significant delays or holds which will impact the ERD. Learn more about turnaround times here.

Clinical Features and Genetics

Clinical Features

Coenzyme Q10 (CoQ10) deficiency is associated with three major forms of clinical phenotypes: a predominantly myopathic form with central nervous system involvement, an infantile encephalomyopathy with renal dysfunction (steroid-resistant nephrotic syndrome), and an ataxic form with cerebellar atrophy (Desbats et al. 2015; Quinzii et al. 2006). Age of onset is variable from birth to the seventh decade. Accurate molecular diagnosis of Coenzyme Q10 deficiency is important for treatment.


Coenzyme Q10 is an essential component of the mitochondrial respiratory chain and an antioxidant. Coenzyme Q10 deficiency is a group of autosomal recessive disorders (Desbats et al. 2015; Yubero et al. 2015). It can be caused by defects in the genes directly involved in the biosynthesis of Coenzyme Q10 (primary deficiency) or unrelated to Coenzyme Q10 biosynthesis (secondary deficiency) as listed below. The spectrum of pathogenic variants throughout these genes includes all types of changes (Human Gene Mutation Database).

Primary Coenzyme Q10 deficiency: PDSS1, PDSS2, COQ2, COQ4, COQ6, COQ9, ADCK3/COQ8A, and ADCK4/COQ8B

Secondary Coenzyme Q10 deficiency: APTX, ETFDH, ETFA, and ETFB

See individual gene test descriptions for more information on molecular biology of gene products.

Clinical Sensitivity - Sequencing with CNV PGxome

Screenings for pathogenic variants in the associated genes in a large cohort of patients with Coenzyme Q10 deficiency have not been reported. To date, studies have focused on individual genes in a limited number of families. Therefore, mutation detection rate of this panel is unknown.

Large deletions and/or duplications have been documented in the Human Gene Mutation Database (HGMD) in the following genes, but are relatively uncommon: ADCK3/COQ8A, COQ4, ETFDH, ETFA, and APTX.

No large deletions or duplications have been reported in the other 7 genes of the current panel.

Testing Strategy

This test is performed using Next-Gen sequencing with additional Sanger sequencing as necessary.

This panel typically provides 99.6% coverage of all coding exons of the genes plus 10 bases of flanking noncoding DNA in all available transcripts along with other non-coding regions in which pathogenic variants have been identified at PreventionGenetics or reported elsewhere. We define coverage as ≥20X NGS reads or Sanger sequencing. PGnome panels typically provide slightly increased coverage over the PGxome equivalent. PGnome sequencing panels have the added benefit of additional analysis and reporting of deep intronic regions (where applicable).

Dependent on the sequencing backbone selected for this testing, discounted reflex testing to any other similar backbone-based test is available (i.e., PGxome panel to whole PGxome; PGnome panel to whole PGnome).

Indications for Test

Candidates for this test are patients with Coenzyme Q10 deficiency either primarily or secondarily. This test especially aids in a differential diagnosis of similar phenotypes by analyzing multiple genes simultaneously.

Ordering Options

We offer several options when ordering sequencing tests. For more information on these options, see our Ordering Instructions page. To view available options, click on the Order Options button within the test description.

myPrevent - Online Ordering

  • The test can be added to your online orders in the Summary and Pricing section.
  • Once the test has been added log in to myPrevent to fill out an online requisition form.
  • PGnome sequencing panels can be ordered via the myPrevent portal only at this time.

Requisition Form

  • A completed requisition form must accompany all specimens.
  • Billing information along with specimen and shipping instructions are within the requisition form.
  • All testing must be ordered by a qualified healthcare provider.

For Requisition Forms, visit our Forms page

If ordering a Duo or Trio test, the proband and all comparator samples are required to initiate testing. If we do not receive all required samples for the test ordered within 21 days, we will convert the order to the most effective testing strategy with the samples available. Prior authorization and/or billing in place may be impacted by a change in test code.
