Test Overview & Methodology
The TTC7A gene is critical for intestinal epithelial homeostasis and immune function. This NGS test analyzes the entire coding region and splice sites to detect pathogenic variants causing multiple intestinal atresia, often syndromic with combined immunodeficiency.
| Feature | Our TTC7A NGS Test | Closest Alternative |
|---|---|---|
| Method | NGS (Next-Generation Sequencing) | Sanger sequencing (single exon screening) |
| Coverage | Full gene ± 20 bp intronic flanks, CNV detection | Selected exons only |
| Turnaround | 3–4 Weeks | 4–6 Weeks (fragmented) |
| Sample Types | Whole blood, DNA, or dry blood spot (FTA card) | Typically blood only |
Physician Insight & Safety Protocols
“As a clinical geneticist, I emphasize that a positive TTC7A result is not a diagnosis in isolation. It must be correlated with intestinal biopsy findings, immune function panels, and the child’s clinical phenotype. Parents, your pediatrician and geneticist will guide you through the meaning of any variant, especially with respect to reproductive options and potential hematopoietic stem cell transplantation.”

Critical Medication Advisory
Do not discontinue prescribed medication or modify therapy without consulting your treating physician. This test does not replace clinical monitoring or immediate surgical intervention.
Exclusion Criteria & Emergency Red Flags
- Patients requiring urgent surgical bowel resection are not eligible for home collection – proceed directly to hospital.
- If you observe bilious vomiting, abdominal distension, or failure to pass meconium in a newborn, call emergency services immediately.
- This test is not indicated for acute care; it is elective and requires genetic counseling before sampling.
Patient FAQ & Clinical Guidance
1. What exactly does the TTC7A gene test detect and how reliable is it?
This test identifies pathogenic or likely pathogenic variants across the entire TTC7A coding sequence with 99% analytical sensitivity and specificity, confirming the molecular cause of multiple intestinal atresia and associated immunodeficiency when clinical signs are present.
2. Does the test require fasting or special preparation?
No special preparation is required; a single blood sample or dried blood spot on an FTA card is sufficient. Prior genetic counseling to document family history is strongly recommended before sampling.
3. Can this test be used for prenatal diagnosis of multiple intestinal atresia?
Yes, with prior genetic counseling and parental variant confirmation, TTC7A NGS can be applied to amniocytes or chorionic villus sampling. Prenatal testing must follow UAE regulatory oversight for minors and requires explicit consent.
4. How long does the result take and will I receive medical explanation?
Results are available within 3 to 4 weeks, followed by a telephonic consultation with a clinical geneticist to interpret the report and discuss follow-up recommendations.
5. What if I need the sample collected at home?
Home collection is available through our VIP Mobile Phlebotomy service with temperature-controlled cold-chain, operating daily from 8 AM to 11 PM. Exclusions apply for acute surgical cases as noted in the safety protocol.
