Overview
The purpose of this NGS genetic test is to detect pathogenic variants in the TECR gene and confirm the clinical diagnosis of autosomal recessive intellectual disability type 14. It also helps provide accurate genetic counselling and recurrence risk information to the affected individual and family.
- Test Code
- 4261
- Price
- ₹20,000
- Sample Type
- Blood or Extracted DNA or One drop Blood on FTA Card
- Result Time
- Reports are usually available within 3 to 4 weeks after the sample reaches the laboratory.
- Fasting Required
- No
- Method
- Next-Generation Sequencing (NGS)
Sample Collection
No special preparation or fasting is required. Please carry the test requisition form and a valid government ID. A genetic counselling session is recommended before sample collection to draw a pedigree chart of affected family members and to explain the implications of the test.
Method: Peripheral blood draw or FTA card spot or extracted DNA submission
Laboratory Analysis
A trained phlebotomist will collect the required sample: peripheral blood in an EDTA vacutainer, one drop of blood on an FTA card, or extracted DNA as per laboratory instructions. The procedure is quick and routine.
Report Delivery
The sample will be transported to the laboratory under controlled conditions. Reports are generally issued within 3 to 4 weeks. The clinical report and raw data files will be shared through the online portal, email and WhatsApp. Please discuss the report with your referring doctor or genetic counsellor.
Timeline: Reports are usually available within 3 to 4 weeks after the sample reaches the laboratory.

About This Test
Who Should Get This Test
The purpose of this NGS genetic test is to detect pathogenic variants in the TECR gene and confirm the clinical diagnosis of autosomal recessive intellectual disability type 14. It also helps provide accurate genetic counselling and recurrence risk information to the affected individual and family.
How to Prepare
- Ensure the sample container, FTA card or DNA vial is correctly labelled with patient name and unique identifier
- If providing an FTA card, allow the blood spot to air dry before placing it in the protective pouch
- For extracted DNA, store and transport the DNA at the recommended temperature as per laboratory instructions
- Inform the laboratory about any recent blood transfusion, bone marrow transplant, or stem cell treatment
- Complete the clinical history form and pedigree details accurately
Doctor's Notes
Reviewed by Dr SULOCHANA HEMCHANDRA HOLLA — MBBS, MD (Medical Genetics) · Reg. No. 8532
"As an obstetrician involved in preconception and prenatal counselling, I strongly recommend confirming the TECR variant before discussing prenatal options. A molecular diagnosis allows families to understand recurrence risk accurately and make informed reproductive decisions."

Test Parameters & Specifications
Sample Stability
- Clotted or haemolysed blood sample
- Mislabelled sample or mismatch between requisition form and sample
- Insufficient or contaminated FTA card spot
- Degraded or improperly stored extracted DNA
- Sample received after a prolonged transport delay without proper temperature control
Understanding Your Results
Pathogenic or likely pathogenic variant detected
Clinically consistent with TECR-related autosomal recessive intellectual disability type 14. Genetic counselling and parental follow-up testing are recommended.
No pathogenic variant detected
Does not exclude MRT14 or other genetic causes of intellectual disability; further evaluation may be considered based on clinical judgement.
Variant of uncertain significance (VUS)
More evidence is needed. Family segregation analysis and additional clinical correlation may help clarify the clinical significance.
Seek consultation if a child has global developmental delay, intellectual disability, speech or language delay, seizures, abnormal muscle tone, or a family history of autosomal recessive intellectual disability. A clinical geneticist or specialist should be consulted before and after genetic testing.
Limitations
- ⚠This NGS test may not reliably detect deep intronic variants, large copy-number variations, or structural rearrangements involving the TECR gene
- ⚠A negative result does not exclude all genetic and non-genetic causes of intellectual disability
- ⚠A variant of uncertain significance may require additional family studies and clinical correlation
- ⚠Clinical interpretation should always be done by a qualified geneticist or specialist
Risks & Considerations
- ●Mild pain or bruising at the venipuncture site
- ●Dizziness or fainting during blood collection
- ●Psychological impact of receiving a genetic result
Interfering Factors
- ●Recent allogeneic bone marrow transplant may affect DNA test results
- ●Blood transfusion within 7 days may cause dilution of patient DNA
- ●Poor sample quality or degraded extracted DNA
- ●Inadequate or contaminated FTA card spot
- ●Mislabelled samples or incomplete requisition details
