Provider FAQs

WHAT TESTING IS INCLUDED IN THE DIAGNOSTIC TESTING PROGRAM?

All testing is performed at our designated laboratory, Revvity Omics.

  • Genetic Testing: Testing provides detection of deletions, duplications, and smaller point mutations in the DMD gene via next generation sequencing (NGS). The program can also provide targeted testing for individuals with a known familial variant, and repeat testing for individuals tested with older molecular technologies. The Decode Duchenne genetic counselors can help determine which tests are needed.
  • Serum Creatine Kinase: Serum CK kinase testing can also be ordered through the Decode Duchenne program. For information on CK testing and its’ benefits, click here.
  • Comprehensive Neuromuscular Disorders Panel: A next generation sequencing panel of 133 genes associated with neuromuscular disorders will be offered to the ordering provider following a negative comprehensive DMD test for a symptomatic patient. You can find additional information on this panel and the genes included on the Revvity Omics website.
  • RNA Sequencing: If a patient has undergone genetic testing and a causative genetic variant has not been identified, they may qualify for RNA sequencing. This testing is currently offered on a research basis, and requires a muscle biopsy sample. This program is currently on hold. Please email decode@parentprojectmd.org for more information.

WHAT TESTING IS INCLUDED IN THE CARRIER TESTING PROGRAM?

Decode Duchenne carrier testing includes testing for deletions, duplications and smaller point mutations through targeted testing of the DMD gene based on the known familial variant. If you have a patient with no known genetic change in the family, please contact a Decode Duchenne Genetic Counselor.

HOW LONG DOES IT TAKE THE TEST RESULTS TO COME BACK?

Results are typically available in 2 weeks after the sample and all necessary paperwork is submitted.

DOES MY PATIENT NEED AN INSURANCE DENIAL TO USE DECODE DUCHENNE?

No, we do not require proof of insurance denial.

MY PATIENT NEEDS RE-TESTING. CAN THEY USE DECODE DUCHENNE?

Absolutely, simply proceed as you would for any other patient.

WHERE DO I GET THE TEST REQUISITION?

Both diagnostic and carrier/asymptomatic test requisitions are available on their respective pages. The diagnostic testing requisition is also available through our partner laboratory, Revvity Omics.

DOES DECODE DUCHENNE PROVIDE FREE CARRIER TESTING?

Yes! Please complete a carrier/asymptomatic test requisition, and submit through secure email (decode@parentprojectmd.org) or fax (404-935-0636) to the Decode Duchenne team. If approved, we will send the TRF to Revvity and ship a saliva kit directly to your patient to collect their sample.

WHAT IF MY PATIENT ISN’T REGISTERED IN THE DUCHENNE REGISTRY?

While we strongly encourage all patients and families with Duchenne or Becker to join The Duchenne Registry, registering is completely voluntary. We ask that you share information about the Registry with your Duchenne and Becker patients and families, and explain the benefits of joining the Registry.

We know that not all patients are able to register at the time of their testing, and many may not be ready to take this step. We have a Registry postcard that is easy to give families while they are in clinic and a helpful reminder once they are home. Please contact us if you would like Registry postcards for your clinic.

How do I know if my patient qualifies for RNA sequencing?

Symptomatic patients who have undergone comprehensive testing of the DMD gene with negative results or a variant of uncertain significance may qualify for RNA sequencing. Please contact a Decode Duchenne genetic counselor for more information.
