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 of muscle stiffness, cramping, or weakness.
  • ✓Family history of myotonia congenita.
  • ✓Diagnosis of a neurological disorder with muscle involvement.
  • ✓Genetic counseling for individuals with related symptoms.
  • ✓Family planning for those with a family history of the condition.

In plain language

What this test helps you understand

This test helps confirm or rule out a diagnosis of myotonia congenita caused by mutations in the CLCN1 gene. It can also identify carriers within a family.
The CLCN1 Gene Myotonia Congenita NGS Genetic DNA Test is a diagnostic tool using Next-Generation Sequencing (NGS) technology. It identifies mutations in the CLCN1 gene, which are responsible for myotonia congenita, a genetic disorder affecting muscle relaxation. This test is valuable for individuals experiencing muscle stiffness and weakness, providing clarity on their condition and guiding treatment strategies. The test specifically detects mutations in the CLCN1 gene, which encodes a chloride channel important for muscle function. By analyzing genetic material, healthcare providers can determine if a patient has myotonia congenita or is a carrier of the genetic mutation. Understanding your results involves interpreting the presence or absence of mutations in the CLCN1 gene. A positive result may confirm a diagnosis, while a negative result requires discussion with a healthcare provider for full understanding. This test can provide accurate diagnosis, inform family planning, enable access to targeted therapies, and offer peace of mind regarding genetic risks.

Questions people ask

Frequently asked questions

Myotonia congenita is a genetic disorder characterized by muscle stiffness (myotonia) that worsens with rest and improves with activity.
Individuals experiencing symptoms like muscle stiffness or weakness, or those with a family history of myotonia congenita, should discuss this test with their doctor.
The test analyzes a sample of your blood or DNA to look for specific changes (mutations) in the CLCN1 gene.
A healthcare provider will interpret the results based on your symptoms and family history. A positive result indicates mutations in the CLCN1 gene.
Yes, identifying carriers or affected individuals can help families understand the risk of passing the condition to future generations.
We have branches across Kenya, including Nairobi, Mombasa, and Kisumu, and offer home sample collection services. Contact us to book.
