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

Pulmonary fibrosis (PF) is a chronic progressive lung disease caused by lung scarring. When the scar forms, the lung tissue becomes thicker and losses its ability to transfer oxygen into the bloodstream. The severity and natural course of pulmonary fibrosis varies from person to person. Symptoms of pulmonary fibrosis include shortness of breath, dry cough, weight loss and fatigue. The etiology of pulmonary fibrosis is varied and most cases of pulmonary fibrosis have no known cause called idiopathic pulmonary fibrosis (IPF). It is estimated that the prevalence of IPF is 50 per 100,000 (Raghu et al. 2006). Pulmonary fibrosis also occurs in families, suggesting genetic factors predispose some individuals to develop pulmonary fibrosis (Wolters et 2014).

Pulmonary surfactant generated by type II alveolar epithelial cells is a mixture of phospholipids and proteins. Surfactant dysfunction disorders can be caused by pathogenic variants in genes critical for the production and function of pulmonary surfactant. The clinical presentations of surfactant dysfunction range from neonatal respiratory failure to interstitial lung disease. These disorders can be familial or sporadic cases (Gower et al. 2011).


Pulmonary fibrosis and surfactant dysfunction disorders are a group of genetically heterogeneous disorders caused by various interactions between genetic components and environmental exposures. Familial inheritance can be autosomal dominant (AD), autosomal recessive (AR), and sex-chromosome linked. The ELMOD2, NKX2-1, SFTPA1, SFTPA2, SFTPC, and TERC genes are associated with autosomal dominant pulmonary disorders. The ABCA3, CSF2RB, SFTPB and SFTPD genes are associated with autosomal recessive disorders. The TERT gene is associated both autosomal dominant and recessive disorders. See individual gene test descriptions for information on molecular biology of gene products.

Clinical Sensitivity - Sequencing with CNV PGxome

This test should detect causative variants in ~20% of familial pulmonary fibrosis patients (Diaz de Leon et al. 2011; Garcia et al. 2011; van Moorsel et al. 2010).

There are only a few isolated cases reported for large deletions/duplications involving ABCA3, NKX2-1, SFTPB, SFTPC and TERCT. The clinical sensitivity is therefore predicted to be low.

Testing Strategy

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

This panel provides 100% 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

Patients with a strong clinical suspicion for inherited pulmonary fibrosis or surfactant dysfunction.

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.

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.
