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.

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

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

Turnaround Time

18 days on average for standard orders or 13 days 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

Nephrolithiasis is a clinical condition in which urinary supersaturation leads to stone formation in the urinary system (the lumen of the collecting system, ureter, and bladder) (Braun et al. 2016; Halbritter et al. 2015; Gee et al. 2016). Patients with kidney stones may have no symptoms or may present with flank pain, gross or microscopic hematuria, obstruction of one or both kidneys, and urinary infections. It affects 10%-15% of adults in their lifetime. Defects in the ADCY10 gene cause autosomal dominant hypercalciuria with a wide range of onset age from childhood to adult (Braun et al. 2016; Halbritter et al. 2015).

Genetics

ADCY10-associated hypercalciuria is an autosomal dominant disorder (Braun et al. 2016; Halbritter et al. 2015). The ADCY10 gene (32 coding exons) encodes soluble adenylyl cyclase. To date, documented genetic defects of ADCY10 include both missense and truncating variants (Human Gene Mutation Database). Large deletions/duplications have not been reported.

Clinical Sensitivity - Sequencing with CNV PGxome

In an international cohort comprising 272 genetically unresolved individuals (106 children and 166 adults) from 268 families with nephrolithiasis (n=256) or isolated nephrocalcinosis (n=16), Halbritter et al. detected likely (or suspected) causative variants in 14 of 30 analyzed genes, leading to a molecular diagnosis in 14.9% (40 of 268) of all cases (Halbritter et al. 2015). Three families (1.1%) were found to have a heterozygous pathogenic ADCY10 variant.

In another international pediatric cohort comprising 143 individuals under 18 years of age, with nephrolithiasis (n=123) or isolated nephrocalcinosis (n=20), Braun et al. detected likely (or suspected) causative variants in 14 of the same set of 30 genes known nephrolithiasis/nephrocalcinosis genes, leading to a molecular diagnosis in 16.8% (24 of 143) of affected individuals (Braun et al. 2016). Two individual (1.4%) was found to have a heterozygous pathogenic ADCY10 variant.

Testing Strategy

This test provides full coverage of all coding exons of the ADCY10 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 are patients with autosomal dominant hypercalciuria. Testing is also indicated for family members of patients who have known pathogenic variants in the ADCY10 gene.
