Intellectual Disability Panel NGS Genetic Test
Short Name: ID NGS Panel
Also known as: Intellectual Disability NGS Panel, ID Gene Panel, Neurodevelopmental Disorder NGS Panel
Intellectual Disability Panel NGS Genetic Test test available at DNA Labs India for ₹20,000. Uses Next-Generation Sequencing (NGS) on Blood or Extracted DNA or One drop Blood on FTA Card samples. Results in Results are typically delivered within 3 to 4 weeks from the date of sample receipt. Sometimes, additional Sanger validation or variant re-classification may extend the turnaround time. You will receive an alert once the report is available online.. Free home collection in 300+ cities across India.

Overview
The purpose of the Intellectual Disability Panel NGS Genetic Test is to identify pathogenic or likely pathogenic genetic variants that may explain the cause of intellectual disability in an affected individual. This test helps confirm a clinical diagnosis, estimate recurrence risks for family members, guide targeted management and therapy, and provide information for reproductive planning. It is particularly useful when the clinical presentation is non-specific or when other diagnostic tests have been inconclusive.

- Sample Type
- Blood or Extracted DNA or One drop Blood on FTA Card
- Result Time
- Results are typically delivered within 3 to 4 weeks from the date of sample receipt. Sometimes, additional Sanger validation or variant re-classification may extend the turnaround time. You will receive an alert once the report is available online.
- Fasting Required
- No
- Method
- Next-Generation Sequencing (NGS)
Sample Collection
No fasting is required for this test. Please bring a valid ID and any relevant medical records. A genetic counselling session is recommended before the test to draw a pedigree and discuss the implications of the result. List all medications and supplements you are taking for the referring physician.
Method: Venipuncture or FTA card blood spot
Laboratory Analysis
The sample will be collected by venipuncture (blood) or a simple finger-prick spot onto an FTA card. The procedure is quick and causes minimal discomfort. For FTA cards, the blood spot must be allowed to air dry before storing in a sterilised bag.
Report Delivery
You can resume your normal activities immediately. No special precautions are needed after sample collection. The laboratory will process the sample and provide a detailed clinical report. A genetic counsellor may contact you to discuss the results.
Timeline: Results are typically delivered within 3 to 4 weeks from the date of sample receipt. Sometimes, additional Sanger validation or variant re-classification may extend the turnaround time. You will receive an alert once the report is available online.

About This Test
Who Should Get This Test
The purpose of the Intellectual Disability Panel NGS Genetic Test is to identify pathogenic or likely pathogenic genetic variants that may explain the cause of intellectual disability in an affected individual. This test helps confirm a clinical diagnosis, estimate recurrence risks for family members, guide targeted management and therapy, and provide information for reproductive planning. It is particularly useful when the clinical presentation is non-specific or when other diagnostic tests have been inconclusive.
How to Prepare
- Blood sample: Collect in an EDTA vacutainer and gently invert 8-10 times.
- FTA card: Apply one drop of blood onto each circle and air dry for at least 30 minutes.
- Extracted DNA: Provide at least 1-2 µg of high-quality DNA in a DNA elution buffer.
- Label all tubes/cards with the patient's name and date of collection.
Doctor's Notes
Reviewed by Dr SULOCHANA HEMCHANDRA HOLLA — MBBS, MD (Medical Genetics) · Reg. No. 8532
"This comprehensive NGS panel is valuable when intellectual disability is unexplained, especially if dysmorphic features or a family history of neurodevelopmental disorders are present. Genetic results can guide recurrence risk counselling and personalized management."

Understanding Your Results
Pathogenic or Likely Pathogenic Variant Detected
Genetic cause identified; supports diagnosis and enables recurrence risk counselling and targeted management.
Variants of Uncertain Significance (VUS) Detected
Variant(s) found with insufficient evidence to classify as pathogenic or benign; additional segregation or functional studies may be recommended.
No Pathogenic Variants Identified
No clinically actionable variants found in the genes analysed; genetic cause is not excluded and other testing may be warranted.
If your test result reveals a pathogenic or likely pathogenic variant, consult a clinical geneticist or referring physician to discuss the clinical implications, management strategies, and recurrence risks. If a VUS is found, genetic counselling can help clarify next steps. A positive result may also be relevant for other family members.
Limitations
- ⚠This panel does not analyse all known genes associated with intellectual disability; some rare genetic causes may not be detected.
- ⚠Mitochondrial DNA variants may not be detected unless specifically included in the panel.
- ⚠Variants of uncertain significance (VUS) may be reported; results should be interpreted with genetic counselling.
- ⚠Structural chromosomal abnormalities such as large translocations or aneuploidies are not detected by targeted NGS panels.
- ⚠Negative results do not rule out a genetic cause for intellectual disability.
Risks & Considerations
- ●No significant physical risks are associated with blood sample collection; possible minor bruising or discomfort may occur.
- ●Finger-prick FTA card sampling is minimally invasive and safe.
- ●Emotional or psychological impact from a positive, inconclusive, or unexpected result.
- ●Potential privacy concerns; data is securely stored and shared only with the requesting physician.
Interfering Factors
- ●Recent allogeneic bone marrow transplantation or blood transfusion (may affect DNA analysis due to donor DNA)
- ●Sample contamination or improper storage
- ●Maternal cell contamination if sample is from cord blood
- ●Extremely low DNA yield or degraded DNA
- ●Current use of certain medications that may affect DNA quality (rare)
