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 Charcot-Marie-Tooth disease type 2B (CMT2B).
  • ✓Progressive muscle weakness, particularly in the feet and legs.
  • ✓Difficulty with walking or balance.
  • ✓Loss of sensation in the hands or feet.
  • ✓Family history of CMT2B or related neurological disorders.
  • ✓Diagnosis confirmation when clinical suspicion is high.

In plain language

What this test helps you understand

This test helps confirm or rule out a diagnosis of Charcot-Marie-Tooth disease type 2B (CMT2B) by identifying mutations in the RAB7A gene. It can aid in understanding the genetic cause of neurological symptoms and inform clinical management.
The RAB7A Gene CMT2B NGS Genetic DNA Test is a diagnostic tool used to detect genetic changes in the RAB7A gene. Mutations in this gene are linked to Charcot-Marie-Tooth disease type 2B (CMT2B), a condition affecting the peripheral nerves. This test helps identify these specific mutations.

This test utilizes Next-Generation Sequencing (NGS) technology to analyze the RAB7A gene for variations. It is designed for individuals suspected of having CMT2B based on clinical symptoms or family history.

Understanding the genetic basis of CMT2B can provide valuable information for diagnosis, prognosis, and potential management strategies. Discussing the test and its results with a healthcare provider or genetic counselor is important for interpreting the findings and understanding their implications for your health and family.

Questions people ask

Frequently asked questions

CMT2B is a genetic disorder affecting the peripheral nerves, leading to symptoms like muscle weakness, sensory loss, and foot deformities.
Individuals with symptoms like progressive muscle weakness, balance problems, or sensory loss, especially with a family history of similar conditions, should discuss this test with their doctor.
The test uses advanced NGS technology for high accuracy in detecting mutations within the RAB7A gene. However, it only tests for mutations in this specific gene.
Results will be provided in a report. It is crucial to discuss these results with your healthcare provider or a genetic counselor to understand their meaning and implications.
Yes, genetic counseling before and after testing is highly recommended to understand the test, its implications, and how results might affect you and your family.
A blood sample is typically required for this test. We offer home sample collection in major cities; please inquire for details.
