Targeted Testing

Targeted Variants (Test #100, 200, 300, 990, 1400, 14028)

We offer single (Test Code 100), double (Test Code 200), or triple (Test Code 300) variant sequencing for any of the genes on our test menu. Prenatal testing (Test Code 990) is also available; for more information click here. Targeted testing for relatives of patients who were identified to have a copy number variant is available via various methodologies, see additional details below. Targeted mitochondrial testing is available via Test Code 14028.

Indications For Test

Candidates for this test are:

  • Family members who may have familial pathogenic variants.
  • Patients wishing to confirm research results.
  • Setting phase of variants.
  • Clarifying interpretation of variants.

Mitochondrial Genome via NGS

To order family follow-up for mitochondrial genome via NGS, please order Test Code 14028, price $590. Only the variant of interest (VOI) will initially be reported, but reflexing to the entire mitochondrial genome is available upon request for no additional charge.

Deletions/Duplications via aCGH

Targeted testing (Test Code 1400) for gross deletions/duplications discovered by aCGH will be available for family members of the proband only if we are able to test the del/dup by PCR. If this is not possible, then the full gene deletion/duplication test (Test Code 600) may be necessary. Please contact us if you have questions about ordering family studies for deletions/duplications.

Family Targeted Variant Testing

PreventionGenetics offers no-cost targeted testing in certain situations. See our Family Targeted Variant Testing Policy for more information.


Order through the myPrevent portal or see our Targeted Variant Test Requisition Form on our Forms page.

Positive Controls

Prenatal testing requests for targeted variants requires positive controls. For other test requests, if a positive control is not provided, negative results will carry a limitation stating that PreventionGenetics did not have the opportunity to verify that we can detect the variant in this family.

Please label the sample and Test Requisition Form: "POSITIVE CONTROL ONLY-No Report". We will not issue a report for samples submitted as positive controls. Please include the outside laboratory report.

Prenatal Testing

Please see our Prenatal Policy for details of prenatal testing. If Test Code 990 is ordered (Targeted Prenatal Variants), parents are offered testing at no charge.

This gene may have paralogy issues. Please contact us ( or 715-387-0484, option 2 and we would be happy to explore if we can customize a targeted variant test for you.


This gene is not fully developed in our laboratory. We are happy to customize a targeted variant test. Development typically takes 2-3 weeks. We strongly recommend submitting a positive control specimen.
