Overview

The purpose of this test is to detect mutations in the GYG2 gene that may be associated with autism spectrum disorder. Identification of such genetic changes can help confirm a genetic etiology, guide management, and inform recurrence risk for families.

Next-Generation Sequencing (NGS), Sanger Confirmation
Step 1

Sample Collection

No fasting is required. If you are taking any medications, please inform your referring physician. For FTA card collection, follow the instructions provided in the collection kit.

Method: Peripheral Blood Draw / FTA Card Spot

Step 2

Laboratory Analysis

A trained phlebotomist will collect a small blood sample from your arm vein, or you may provide a single drop of blood on the FTA card.

Step 3

Report Delivery

No restrictions. You may resume normal activities immediately after sample collection.

Timeline: Reports are typically delivered within 3 to 4 weeks (21-28 days) after the sample reaches the laboratory.

Patient Instructions

1
Before the Test:Referral from a neurologist is required. A genetic counseling session will be conducted to draw a family pedigree before sample collection.
2
During the Test:Provide a small blood sample or a spot of blood on FTA card. The sample will be sent to our NGS laboratory for analysis.
3
After the Test:You will receive an email or SMS notification once the report is ready. A genetic counselor will be available to discuss the results.

About This Test

Who Should Get This Test

The purpose of this test is to detect mutations in the GYG2 gene that may be associated with autism spectrum disorder. Identification of such genetic changes can help confirm a genetic etiology, guide management, and inform recurrence risk for families.

How to Prepare

  • For blood sample: collect in an EDTA vacutainer and mix gently by inverting the tube.
  • For FTA card: apply one drop of blood to the specified circle and allow to dry for at least 1 hour.
  • Label the sample with patient name, date, and time of collection.

Understanding Your Results

The clinical interpretation of GYG2 gene sequencing results should be performed by a qualified geneticist. Variants are classified based on standard guidelines and correlated with clinical findings.
Positive result: presence of a pathogenic or likely pathogenic variant in the GYG2 gene, which may explain the patient's clinical presentation.
Negative result: no clinically significant variants found; this does not exclude a genetic cause for autism.
Variant of Uncertain Significance (VUS): a change was detected but its clinical significance is unclear; further family studies may be recommended.
⚠️ When to Consult a Doctor:

If you receive a positive or uncertain result, we recommend booking an appointment with a clinical geneticist for personalized guidance and risk assessment.

Limitations

  • ⚠This test detects only mutations in the GYG2 gene and does not rule out other genetic causes of autism.
  • ⚠Sequence variants in regulatory regions or deep intronic regions may not be captured by standard NGS.
  • ⚠Results should be interpreted in the context of clinical symptoms, family history, and genetic counseling.

Risks & Considerations

  • ●There are no major risks associated with blood collection.
  • ●Slight bruising at the puncture site may occur.
  • ●Rarely, dizziness or fainting during blood draw may occur.

Interfering Factors

  • ●Insufficient DNA quantity or quality
  • ●Contamination from multiple samples
  • ●Copy number variations may not be detected by standard NGS analysis
