Overview

The purpose of this test is to identify genetic mutations that may increase the risk of developing cataracts, aiding in early risk assessment, personalized health planning, and informed decision-making for eye care.

Test Code
1331
Price
₹28,665
Sample Type
Whole blood
Result Time
45 working days from sample receipt at the laboratory.
Fasting Required
No
Method
NGS, Sanger sequencing
Step 1

Sample Collection

Complete and sign the mandatory Whole Exome Sequencing Consent Form (Form 37). Ensure proper identification and avoid eating or drinking for at least 30 minutes before blood draw, though fasting is not required.

Method: Venipuncture

Step 2

Laboratory Analysis

A healthcare professional will perform a venipuncture to collect 10 mL of whole blood into two Lavender Top (EDTA) tubes. The process is quick and minimally invasive.

Step 3

Report Delivery

Label samples correctly and ship refrigerated immediately. Do not freeze. Ensure the consent form is included with the sample.

Timeline: 45 working days from sample receipt at the laboratory.

Patient Instructions

1
Before the Test:Schedule a comprehensive eye exam and genetic counseling session to discuss the test's implications and prepare the consent form.
2
During the Test:A simple blood draw is performed; the process takes about 10-15 minutes with minimal discomfort.
3
After the Test:Wait for the report in approximately 45 working days. Follow up with a genetic counselor or ophthalmologist to discuss results.

Understanding Your Results

Results indicate the presence or absence of genetic variants associated with cataracts. A positive result suggests an increased genetic risk, while a negative result means no known pathogenic variants were detected in the analyzed genes.
Positive result: Pathogenic variant detected; consult a geneticist for risk management and family counseling.
Negative result: No pathogenic variants found; but clinical evaluation is still recommended if symptoms exist.
Variant of uncertain significance: Further testing or monitoring may be advised.
Results should be correlated with family history and clinical symptoms.
⚠️ When to Consult a Doctor:

Consult a doctor if you have a family history of cataracts, experience symptoms like blurred vision or glare sensitivity, or if the test results indicate a positive genetic risk for further evaluation and management.

Limitations

  • ⚠This test does not diagnose cataracts but assesses genetic risk
  • ⚠May not detect all genetic variants or mutations
  • ⚠Results should be interpreted in conjunction with clinical evaluation

Risks & Considerations

  • ●Minor bruising or discomfort at the blood draw site
  • ●Very low risk of infection or fainting
  • ●No significant health risks from the genetic test itself

Interfering Factors

  • ●Improper sample collection or handling
  • ●Contamination of blood sample
  • ●Recent blood transfusions may affect DNA analysis

Frequently Asked Questions

What is Nx Gen Sequencing for cataracts?
It is a genetic test that analyzes DNA to identify mutations in genes associated with increased risk of developing cataracts, using advanced sequencing technologies.
How much does the cataract genetic test cost in India?
The test costs INR 28665.0 at DNA Labs India, which includes sample collection, analysis, and report generation.
What sample is required for the test?
A 10 mL whole blood sample collected in two Lavender Top (EDTA) tubes is required. The sample must be shipped refrigerated.
How long does it take to get the test results?
Results are typically available within 45 working days from the date of sample receipt at the laboratory.
Is this test accurate for detecting cataract risk?
Yes, the test uses NGS and Sanger sequencing for high accuracy, but it assesses genetic risk rather than diagnosing cataracts directly.
Who should consider taking this test?
Individuals with a family history of cataracts, early onset symptoms, or those seeking genetic counseling for hereditary eye conditions.
Can this test diagnose cataracts?
No, it identifies genetic mutations that may increase risk, but diagnosis requires a clinical eye examination by an ophthalmologist.
Is home sample collection available for this test?
Yes, DNA Labs India offers free home sample collection for online bookings across India in numerous cities.
What genes are analyzed in this test?
The test analyzes genes including AGK, CRYAA, CRYAB, CRYBB1, CRYBB3, CTDP1, FYCO1, GCNT2, GJA8, HSF4, LIM2, SIL1, and TDRD7.
How is the genetic test performed?
The test involves DNA extraction from blood, followed by Next-Generation Sequencing and Sanger sequencing to detect mutations in the specified genes.
What should I do if I get a positive result?
If a positive result is detected, consult a geneticist or ophthalmologist for personalized risk management, regular eye screenings, and family counseling.
Is the test covered by health insurance schemes?
Coverage varies by scheme and provider; it is recommended to check with your insurance company or contact DNA Labs India for details.
