Pricing Comments

Our favored testing approach is exome based NextGen sequencing with CNV analysis. This will allow cost effective reflexing to PGxome or other exome based tests. However, if full gene Sanger sequencing is desired for STAT turnaround time, insurance, or other reasons, please see link below for Test Code, pricing, and turnaround time information.

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

The Sanger Sequencing method for this test is NY State approved.

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

Mitochondrial membrane Protein-Associated Neurodegeneration (MPAN) is the third common type of Neurodegeneration with Brain Iron Accumulation (NBIA). It has childhood onset, but occurs across all age groups. The manifestations include cognitive decline, progressive dementia, prominent neuropsychiatric abnormalities, motor neuronopathy, spasticity, dysarthria, dystonia, Parkinsonism and optic atrophy. Brain MRI shows iron accumulation in both globus pallidus and substantia nigra. Cortical and cerebellar atrophy are also common (Hogarth  et al. 2013; Arber et al 2016).


Mitochondrial membrane Protein-Associated Neurodegeneration is inherited in an autosomal recessive manner and is caused by pathogenic variants in the C19orf12 gene. The protein C19orf12 is located on the outer mitochondrial membrane with unclear function (Venco et al. 2015). Pathogenic variants in C19orf12 include missense, nonsense, small deletion and insertion, and splice variants (Hogarth et al. 2013; Tschentscher  et al. 2015; Human Gene Mutation Database). No large deletions or duplications have been reported to be causative for MPAN.

Clinical Sensitivity - Sequencing with CNV PGxome

It has been estimated that pathogenic variants in C19orf12 account for 6-10% of neurodegeneration with brain iron accumulation (NBIA) (Arber et al. 2016).

Testing Strategy

This test provides full coverage of all coding exons of the C19orf12 gene 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 full 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 include patients with symptoms suspected for any type of neurodegeneration with brain iron accumulation (NBIA). This test may also be considered for the reproductive partners of individuals who carry pathogenic variants in C19orf12.

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.
