Understanding Your Results

The interpretation of exome data analysis results is based on the identification and annotation of genetic variants. Variants are classified according to the American College of Medical Genetics and Genomics (ACMG) guidelines into five categories: pathogenic, likely pathogenic, uncertain significance, likely benign, and benign. The report includes a list of variants, their associated genes, and clinical significance. A clinical geneticist or physician should interpret the results in the context of the patient's clinical presentation and family history.
📊

Variant is known to cause disease. Clinical correlation is recommended.

📊

Variant is highly suspected to cause disease. Further testing may be needed.

📊

Variant has unknown impact. Additional family studies or functional assays may be required.

📊

Variant is unlikely to cause disease.

📊

Variant is not associated with disease.

⚠️ When to Consult a Doctor:

If the analysis identifies a pathogenic or likely pathogenic variant, it is essential to consult with a clinical geneticist or the referring physician for further management, genetic counseling, and family screening. Additionally, if variants of uncertain significance are found, a specialist should be consulted to determine the need for additional testing.

Limitations

  • Analysis is limited to exonic regions; intronic and regulatory variants may not be detected
  • Cannot detect large structural variants or repeat expansions reliably
  • Variant interpretation may be inconclusive for variants of unknown significance
  • Requires high-quality extracted DNA; degraded samples may yield poor results

Risks & Considerations

  • No physical risks are associated with this test as it is a bioinformatics analysis.
  • If a blood sample is collected, there is a minimal risk of bruising or infection at the puncture site.

Interfering Factors

  • Poor quality DNA sample
  • Insufficient sequencing coverage
  • Contamination with non-human DNA
  • Errors in reference genome alignment
  • Presence of pseudogenes or homologous regions

Frequently Asked Questions

What is human exome data analysis?
Human exome data analysis is the process of analyzing the protein-coding regions of the genome (exome) to identify genetic variants that may be associated with diseases.
What is variant calling?
Variant calling is the process of identifying differences between an individual's genome and a reference genome, such as single nucleotide changes or insertions/deletions.
What is variant annotation?
Variant annotation involves adding functional information to identified variants, such as their location in a gene, predicted impact on protein function, and known disease associations.
What is the cost of this test?
The cost is INR 15000, which is a discounted price for online bookings.
What sample is required?
The sample type is extracted DNA. If you do not have extracted DNA, a blood or saliva sample can be collected for DNA extraction.
How long does it take to get results?
The turnaround time is 4 weeks from the receipt of the sample.
Is home sample collection available?
Yes, we offer free home sample collection for online bookings in many cities across India.
What conditions can this test help diagnose?
This test can help diagnose genetic disorders associated with developmental delays, intellectual disability, birth defects, and other inherited conditions.
Will I receive a report?
Yes, you will receive a detailed report with variant calling and annotation results, including interpretation.
Is this test covered by insurance?
Insurance coverage is not guaranteed and depends on your policy. We recommend checking with your insurance provider.
Can this test be done for research purposes?
Yes, this service can be used for research applications, but it is primarily intended for clinical diagnostic use.
What is the quality of the analysis?
We use state-of-the-art bioinformatics tools and follow ACMG guidelines for variant interpretation to ensure high accuracy.
