Overview
The purpose of this test is to detect pathogenic or likely pathogenic variants in the DNM2 gene. Such variants are associated with DNM2-related autosomal dominant intermediate Charcot-Marie-Tooth disease type B and centronuclear myopathy. Identifying a genetic cause helps confirm the clinical diagnosis, allows for better family counselling, and may guide future management and surveillance plans.

Doctor's Notes
Reviewed by Dr SULOCHANA HEMCHANDRA HOLLA — MBBS, MD (Medical Genetics) · Reg. No. 8532
"Genetic testing for DNM2-associated disorders should always be paired with pre-test genetic counselling so that patients and families understand the possible results and their implications. If the test is performed during pregnancy or for family planning, a broader discussion with a clinical geneticist and obstetrician is important."

Understanding Your Results
If you or your family member have symptoms such as progressive muscle weakness, difficulty walking, foot drop, hand weakness, ptosis, dysphagia, or breathing difficulties, please consult a neurologist or a clinical geneticist. A doctor can help decide whether DNM2 gene testing is appropriate.
Risks & Considerations
- ●Minimal risk of bruising or discomfort at the venipuncture site
- ●Very low risk of infection or prolonged bleeding
Interfering Factors
- ●Poor quality or degraded DNA
- ●Low DNA quantity
- ●Maternal cell contamination
- ●Incomplete coverage of certain DNM2 gene regions due to GC-rich areas
