Overview

The purpose of the COL2A1 gene NGS genetic test is to identify pathogenic mutations in the COL2A1 gene that are associated with Otospondylomegaepiphyseal dysplasia (OSMED). This test aids in confirming a clinical diagnosis, providing prognostic information, and enabling genetic counseling for affected families. It is also useful for prenatal diagnosis in at-risk pregnancies and for carrier testing in family members.

Understanding Your Results

The COL2A1 gene NGS test identifies sequence variants in the COL2A1 gene. Results are interpreted based on ACMG guidelines. A pathogenic or likely pathogenic variant confirms the diagnosis of OSMED. A negative result does not exclude the diagnosis, as mutations may be present in other genes or in regions not covered.
📊

Pathogenic variant detected

Confirms diagnosis of OSMED. Genetic counseling recommended for family planning.

📊

Likely pathogenic variant detected

Highly suggestive of OSMED; further segregation analysis may be helpful.

📊

Variant of uncertain significance (VUS)

Cannot determine clinical significance; additional testing of family members may be needed.

📊

No pathogenic variant detected

Does not rule out OSMED; consider testing other genes or alternative diagnoses.

⚠️ When to Consult a Doctor:

If you or your child have symptoms suggestive of OSMED, such as short stature, hearing loss, joint abnormalities, or skeletal dysplasia, consult a clinical geneticist or orthopedic specialist for evaluation and genetic testing.

Limitations

  • This test detects mutations in the COL2A1 gene only; other genes may also cause similar phenotypes.
  • Large deletions/duplications may not be detected by standard NGS; additional testing may be required.
  • Variant of uncertain significance (VUS) may be reported; further family studies may be needed.
  • Test does not assess non-coding regulatory regions beyond standard coverage.

Risks & Considerations

  • Minimal risk of bruising or infection at the blood draw site
  • Psychological impact of genetic results
  • Potential for uncertain results (VUS)

Interfering Factors

  • Contamination of sample with foreign DNA
  • Insufficient DNA quantity or quality
  • Presence of maternal cell contamination in prenatal samples
  • Recent blood transfusion (for blood samples)

Frequently Asked Questions

What is Otospondylomegaepiphyseal dysplasia (OSMED)?
OSMED is a rare genetic disorder affecting bone and cartilage development, caused by mutations in the COL2A1 gene. It leads to short stature, hearing loss, and joint abnormalities.
How is OSMED diagnosed?
Diagnosis is based on clinical features, imaging, and genetic testing. The COL2A1 NGS test confirms the diagnosis by identifying pathogenic mutations.
What is the cost of the COL2A1 gene NGS test in India?
The test costs approximately INR 20,000 at DNA Labs India, with home sample collection available at no extra charge.
What sample is required for the test?
A blood sample (2-3 ml in EDTA) or a single drop of blood on an FTA card is required.
Is fasting required before the test?
No, fasting is not required for this genetic test.
How long does it take to get results?
Results are typically available within 3 to 4 weeks after the sample reaches the laboratory.
Can the test be done during pregnancy?
Yes, prenatal testing can be performed using appropriate samples (e.g., amniotic fluid or chorionic villus) after genetic counseling.
What does a positive result mean?
A positive result (pathogenic variant) confirms the diagnosis of OSMED and helps in management and family planning.
What if the result is negative?
A negative result does not exclude OSMED; other genetic causes may be considered. Further testing may be recommended.
Is genetic counseling included?
Yes, a genetic counseling session is included in the test price to discuss the implications and draw a pedigree chart.
Is home sample collection available?
Yes, we offer free home sample collection for online bookings across major cities in India.
Are there any risks associated with the test?
The test is safe. The only risk is minor bruising or infection at the blood draw site, which is rare.
