Overview

The purpose of this test is to detect disease-causing variants in the DMD gene to confirm a clinical diagnosis of Becker or Duchenne muscular dystrophy, identify carriers, and provide information for recurrence risk assessment and family planning.

Test Code
4347
ICD Code
G71.0
Price
₹20,000
Sample Type
Blood or Extracted DNA or One drop Blood on FTA Card
Result Time
Results will be shared within 3 to 4 weeks after the sample reaches the laboratory.
Fasting Required
No
Method
Next Generation Sequencing (NGS)
Step 1

Sample Collection

No fasting is required. Please carry photo identification and any previous genetic test reports, muscle biopsy reports, or relevant clinical notes. A genetic counseling session may be arranged before sample collection to review family history and pedigree.

Method: Peripheral venous blood draw or dried blood spot on FTA card

Step 2

Laboratory Analysis

A trained phlebotomist will draw a blood sample from your arm or collect a drop of blood on an FTA card. The procedure takes only a few minutes.

Step 3

Report Delivery

You can resume normal activities immediately. If a blood draw was performed, apply pressure to the site for a minute to reduce bruising.

Timeline: Results will be shared within 3 to 4 weeks after the sample reaches the laboratory.

Patient Instructions

1
Before the Test:No special preparation or fasting is required. A genetic counseling session is recommended before testing to discuss the benefits, limitations, and clinical utility of the test.
2
During the Test:A blood sample is collected or an FTA card blood spot is taken. The procedure is simple and takes only a few minutes.
3
After the Test:You may leave immediately after sample collection. The sample is transported to the laboratory, and results are expected in 3 to 4 weeks.

About This Test

Who Should Get This Test

The purpose of this test is to detect disease-causing variants in the DMD gene to confirm a clinical diagnosis of Becker or Duchenne muscular dystrophy, identify carriers, and provide information for recurrence risk assessment and family planning.

How to Prepare

  • Continue regular medicines unless advised otherwise by your doctor.
  • Ensure the patient's full name, date of birth, and identification details are correctly provided.
  • Bring any previous genetic test reports or muscle biopsy reports, if available.

Doctor's Notes

Reviewed by — MBBS, MD (General Medicine) · Reg. No. 8052

"Becker muscular dystrophy is often suspected when a DMD gene mutation is present but dystrophin is partially produced. This NGS test helps establish a precise genetic diagnosis, estimate recurrence risk, and guide surveillance for cardiac and respiratory complications."

Understanding Your Results

The DMD gene NGS test should be interpreted by a qualified clinical geneticist or genetic counselor in the context of clinical symptoms, family history, and other laboratory investigations.
📊

No pathogenic/likely pathogenic variant detected

Negative result. If clinical suspicion is high, additional deletion/duplication analysis may be required.

📊

Pathogenic/likely pathogenic variant detected

Positive result. Confirms the molecular diagnosis; genetic counseling and family screening are recommended.

📊

Variant of uncertain significance (VUS)

Inconclusive result. Additional family studies or functional evidence may be needed to clarify significance.

⚠️ When to Consult a Doctor:

Consult a neurologist or a medical geneticist if you have symptoms such as progressive muscle weakness, difficulty climbing stairs, calf hypertrophy, family history of DMD/BMD, or elevated creatine kinase without an obvious cause.

Limitations

  • ⚠This test is targeted to the DMD gene and does not rule out other genetic causes of muscular dystrophy.
  • ⚠Large exon deletions or duplications may require reflex MLPA for complete detection.
  • ⚠A variant of uncertain significance may not provide a definitive diagnosis.
  • ⚠Results should always be interpreted in the context of clinical symptoms, family history, and specialist evaluation.

Risks & Considerations

  • ●Blood sample collection may cause minor pain, bruising, or rarely infection.
  • ●FTA card blood spot collection does not involve a needle puncture and carries minimal risk.

Interfering Factors

  • ●Inadequate DNA quality due to sample degradation
  • ●Very large deletions or duplications that may not be captured by standard NGS alone
  • ●Rare deep intronic variants or structural rearrangements not covered by this NGS test
  • ●Low-level somatic or germline mosaicism may be missed
  • ●Contamination of the sample during collection or handling

Frequently Asked Questions

What is the cost of the DMD gene Becker muscular dystrophy NGS genetic test?
The test is priced at INR 20,000. DNA Labs India offers free home sample collection for online bookings across India.
What kind of sample is required for this genetic test?
The test can be performed on whole blood, extracted DNA, or one drop of blood on an FTA card.
How long will it take to get the report?
Reports are usually available within 3 to 4 weeks after the sample is received by the laboratory.
What is the difference between Becker and Duchenne muscular dystrophy?
Both are caused by mutations in the DMD gene. DMD is more severe with early childhood onset, while BMD is milder with a later onset and slower progression because some functional dystrophin is produced.
Who should get this NGS genetic test?
It is recommended for individuals with symptoms suggestive of muscular dystrophy, those with a family history of DMD/BMD, couples planning a family, and at-risk relatives who want to know their carrier status.
Does this test detect all types of DMD gene mutations?
NGS detects single nucleotide variants and small insertions/deletions in coding regions. Large exon deletions or duplications may require additional deletion/duplication analysis such as MLPA for complete coverage.
Is fasting required before the test?
No, fasting is not required.
Will the test identify carriers of DMD/BMD?
Yes, the test can identify pathogenic variants in the DMD gene, which helps in carrier testing for at-risk female relatives.
Is home sample collection available?
Yes, free home sample collection is available for online bookings in multiple cities across India.
What does a negative DMD gene NGS result mean?
A negative result means no disease-causing variant was identified in the tested regions. It does not fully exclude the possibility of large structural rearrangements or rare intronic mutations, so genetic counseling is important.
Why is genetic counselling recommended with this test?
Genetic counseling helps interpret the result in the context of family history and pedigree, explains inheritance and recurrence risk, and supports informed medical and reproductive decisions.
How can I book the DMD gene NGS test at DNA Labs India?
You can book online on the DNA Labs India website or call our customer support for assistance. Free home collection is offered for online bookings.
