Understanding Your Results

The test report will indicate whether a pathogenic variant in the NKX3-2 gene was identified. If a variant is found, its clinical significance is classified based on ACMG guidelines. A positive result confirms the diagnosis of SMMD, while a negative result reduces but does not eliminate the possibility.
📊

Pathogenic variant detected

Confirms diagnosis of SMMD. Autosomal recessive inheritance. Genetic counseling recommended for family planning.

📊

Likely pathogenic variant detected

Highly suggestive of SMMD. Further confirmation may be needed through family studies.

📊

Variant of uncertain significance (VUS)

Cannot be definitively classified. Additional testing of family members may help determine pathogenicity.

📊

No pathogenic variant detected

Does not rule out SMMD. Consider other genetic causes or clinical re-evaluation.

⚠️ When to Consult a Doctor:

Consult a geneticist or pediatrician if you or your child exhibit symptoms of SMMD, such as short stature, skeletal abnormalities, or joint problems. Also, if there is a family history of SMMD, genetic counseling is advised before testing.

Limitations

  • This test does not detect large deletions/duplications or deep intronic variants
  • Variants of uncertain significance may require further family studies
  • Negative result does not rule out SMMD if clinical suspicion is high; other genes may be involved
  • Genetic counseling is recommended for result interpretation

Risks & Considerations

  • Minimal risk of bruising or infection at the blood draw site
  • Psychological impact of genetic results
  • Potential for variants of uncertain significance causing anxiety

Interfering Factors

  • Contamination of sample with foreign DNA
  • Insufficient DNA quantity or quality
  • Presence of maternal cell contamination in prenatal samples
  • Recent blood transfusion (within 2 weeks) may dilute nucleated cells

The cost is Rs 20000 at DNA Labs India, which includes genetic counseling, NGS sequencing, and a comprehensive report.
What sample is required for this test?
Blood (2-3 ml in EDTA tube) or extracted DNA or one drop of blood on an FTA card.
Is fasting required before the test?
No, fasting is not required for this genetic test.
How long does it take to get the results?
The turnaround time is 3 to 4 weeks from sample receipt.
Will I receive raw data files?
Yes, DNA Labs India provides raw data (FASTQ, VCF) along with the clinical report for transparency.
What does the test detect?
It detects mutations in the NKX3-2 gene that cause Spondylo-megaepiphyseal-metaphyseal dysplasia.
Is home sample collection available?
