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

Dent disease is a progressive proximal renal tubulopathy with hypercalciuria, low-molecular-weight proteinuria, and nephrocalcinosis (Devuyst and Thakker 2010). Signs and symptoms of this condition appear in early childhood and progress to end-stage renal disease (ESRD) in early to mid-adulthood. Some patients may develop rickets or osteomalacia. The severity of the disease in affected individuals may vary greatly within the same family.


Dent disease is inherited in an X-linked recessive pattern. Defects in the CLCN5 and OCRL genes account for about 50-60% and 15% of all cases of Dent disease, respectively (Devuyst and Thakker 2010). Dent disease occurs de novo in approximately 10% of patients. The milder features of low-molecular-weight (LMW) proteinuria proteinuria and hypercalciuria present in approximately 70% and 50% of females carriers, respectively. The CLCN5 gene encodes the ClC-5 chloride channel expressed in tubular epithelial cells. So far, genetic defects of CLCN5 found in Dent disease include missense, nonsense, splicing variants, small deletion/insertions and large deletions (Human Gene Mutation Database). The OCRL gene encodes a phosphatidylinositol 4,5-bisphosphate-5-phosphatase and its defects are also associated with Lowe Syndrome. So far, genetic defects of OCRL found in Dent disease include missense, nonsense, splicing variants, small deletion/insertions and large deletions (Human Gene Mutation Database).

Clinical Sensitivity - Sequencing with CNV PGxome

Defects in the CLCN5 and OCRL genes account for about 50-60% and 15% of all cases of Dent disease, respectively (Devuyst et al. 2010).

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

Candidates for this test are patients with Dent disease. Testing is also indicated for family members of patients who have known mutations in the CLCN5 or OCRL gene.

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.
