Testing and Diagnosis

There are many different genetic sequencing tests and you will need to discuss with your doctor which of the available tests is the most appropriate to determine your diagnosis. Most labs will do “panels” or testing of specific groupings of genes. If your doctor suspects you may have a type of Limb Girdle Muscular Dystrophy (LGMD), for example, they may recommend getting an LGMD panel test.  To evaluate for a diagnosis of dysferlinopathy, also referred to as LGMD2B, LGMDR2, Miyoshi Myopathy 1, the testing would need to include the DYSF gene.

There are many genetic labs to choose from for these tests. Depending on the type of sample required, sample collection and return can often be done through the mail. Most labs have private pay and insurance pay options. Many of the US based companies also accept international samples.  You will need to contact the company to confirm and determine the procedure for international samples.

Regardless of where you obtain genetic testing, we highly encourage you to get a copy of your genetic report.  We believe this could help you control how quickly your eligibility for future clinical trials is determined.

Jain Foundation dysferlin-specific sequencing:  The Jain Foundation sponsors testing for patients who are suspected of having dysferlinopathy (LGMD2B/LGMDR2/Miyoshi Myopathy 1). A large NMD panel of more than 100 known NMD genes is utilized for this analysis.  Both clinicians and individuals with suspected dysferlinopathy may apply for testing support by contacting us at patients@jain-foundation.org. We will send you a PDF form to complete and, based on the information on that form, may request additional information.

The Lantern Project: Sanofi Genzyme is partnering with PerkinElmer Genomics to offer a complimentary genetic testing program called The Lantern Project. It offers free diagnostic testing for several disorders, including LGMD.

Rare Genomes Project LGMD: This project enables individuals who have had negative or incomplete results from prior genetic testing to participate in a study using whole-genome sequencing (WGS) to search for additional causes of LGMD. The study will focus on individuals and families who:

  • Have a clinical diagnosis of LGMD
  • Have had prior genetic testing that was negative or did not provide a full genetic explanation
  • Are currently under the care of a neurologist, medical geneticist, or relevant subspecialist
  • Live in the United States
  • Are English-speaking
