01

Start with fit

Is this the right test for you?

The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.

  • ✓Symptoms suggestive of Myotonic Dystrophy Type 1 (e.g., muscle weakness, myotonia, cataracts, cardiac issues)
  • ✓Family history of Myotonic Dystrophy Type 1
  • ✓Prenatal diagnosis (if indicated)
  • ✓Carrier screening (if indicated)
  • ✓Confirmation of clinical suspicion
  • ✓Genetic counseling purposes

In plain language

What this test helps you understand

Diagnosis of Myotonic Dystrophy Type 1 (DM1), a hereditary neuromuscular disorder. Identification of individuals at risk due to family history. Informing management and treatment strategies. Providing information for genetic counseling and family planning.
The Myotonic Dystrophy Type 1 Test is a specialized genetic analysis designed to detect mutations in the DMPK gene. These mutations are the cause of Myotonic Dystrophy Type 1 (DM1), an inherited condition affecting muscles and other body systems. This test is important for individuals experiencing symptoms or those with a family history of DM1.

This test specifically looks for expansions in the CTG repeat region of the DMPK gene. Identifying these mutations is key to diagnosing DM1 and understanding its potential severity and progression.

Individuals experiencing symptoms like muscle weakness, myotonia (difficulty relaxing muscles after contraction), cataracts, or heart problems should consider this test. It is also recommended for individuals with a known family history of Myotonic Dystrophy Type 1.

Benefits of this test include enabling early diagnosis for timely management, providing information for family planning and genetic counseling, and helping to understand the likely course of the condition.

Results will indicate the presence or absence of the specific DMPK gene mutation. A positive result confirms the diagnosis of Myotonic Dystrophy Type 1. Discuss your results with your doctor for proper interpretation and guidance on next steps.

Questions people ask

Frequently asked questions

Myotonic Dystrophy Type 1 (DM1) is an inherited disorder that affects muscles, eyes, heart, and other body systems. It is caused by mutations in the DMPK gene.
Individuals with symptoms like muscle weakness or difficulty relaxing muscles, or those with a family history of DM1, should consider testing.
The test involves analyzing a blood sample for specific genetic mutations (CTG repeat expansions) in the DMPK gene.
A positive result indicates the presence of the DM1 mutation. Your doctor will interpret the results in the context of your symptoms and family history.
The blood draw is a standard procedure and may cause minimal discomfort.
Results are typically available within a few days after sample submission, but confirm the exact turnaround time with the laboratory.
