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 platform).

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

Adams-Oliver syndrome is characterized mainly by aplasia cutis congenita and limb defects. The clinical features include missing skin typically on the top of the skull, tapering fingers, and hyperplastic distal phalanges of the hands and feet. Some patients may have heart problems, including ventricular septal defect and patent ductus arteriosus. Pathogenic variants in ARHGAP31 and RBPJ cause autosomal dominant Adams-Oliver syndrome, while pathogenic variants in DOCK6 and EOGT cause autosomal recessive Adams-Oliver syndrome (Shaheen et al. 2013; Hassed et al. 2012; Isrie et al. 2014).


Pathogenic variants in the DOCK6 gene cause autosomal recessive Adams-Oliver syndrome 2. The DOCK6 protein coded by DOCK6 is a Dock-C subfamily guanine nucleotide exchanger and plays a role in remodeling the actin cytoskeleton. To date, only six pathogenic variants have been reported. They include nonsense, splicing, and small deletions and duplications (Shaheen et al. 2011; Shaheen et al. 2013; Human Gene Mutation Database).

Clinical Sensitivity - Sequencing with CNV PGxome

In one study, DOCK6 pathogenic variants were identified in 2 out of 5 families with autosomal recessive Adams-Oliver syndrome (Shaheen et al. 2013).

Testing Strategy

This test provides full coverage of all coding exons of the DOCK6 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 symptoms consistent with autosomal recessive Adams-Oliver syndrome. This test may also be considered for the reproductive partners of individuals who carry pathogenic variants in DOCK6.

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.
