Overview: NNT Gene Glucocorticoid Deficiency Type 4 – Genetic Test
NNT (Nicotinamide Nucleotide Transhydrogenase) gene sequencing via Genetic Test interrogates all coding exons, splice-site junctions, and deep intronic regions of the NNT gene (chromosome 5p12) to identify pathogenic single-nucleotide variants (SNVs), small insertions/deletions (indels), and copy-number variations (CNVs) at read depths exceeding 100×.
باختصار: هذا الفحص الجيني الشامل يكشف الطفرات المسببة لنقص القشرانيات السكرية الوراثي من النوع الرابع بدقة تشخيصية عالية.

Physician Insight & Safety Protocol
Dr. PRABHAKAR REDDY
DHA License No. 61713011 — Consultant Clinical Pathologist & Molecular Geneticist
"A positive NNT variant finding on this NGS panel is a critical molecular clue, but it must always be correlated with serum cortisol, ACTH, and plasma renin activity before reaching a clinical diagnosis. This test provides the genetic blueprint; your endocrinologist integrates it with biochemical phenotype data to guide lifelong glucocorticoid and, when indicated, mineralocorticoid replacement therapy. Never interpret a VUS (Variant of Uncertain Significance) as benign without confirmatory familial segregation studies."
Medication & Safety Warning
Do not discontinue prescribed glucocorticoid or mineralocorticoid medications without consulting your treating physician. This genetic test is diagnostic and prognostic; it does not replace emergency management of adrenal crisis.
Exclusion Criteria & Emergency Red Flags
- Exclusion Criteria: This test is not indicated for acute adrenal crisis management. Genetic testing is deferred in hemodynamically unstable patients. Neonatal screening for congenital adrenal hyperplasia (CAH) must precede NNT sequencing in infants with ambiguous genitalia or salt-wasting crisis.
- ER Red Flags: If the patient experiences severe vomiting, diarrhoea, hypotension, hypoglycaemia, altered consciousness, or shock, proceed immediately to the nearest Emergency Department. Suspect Adrenal Crisis — administer parenteral hydrocortisone per protocol.
- Sample Rejection Criteria: Haemolysed whole blood, insufficient DNA yield (<50 ng/µL), or FTA cards with visible contamination will require recollection.
- Paediatric Note (CDS Law 2026): Genetic testing of minors requires documented informed consent from a legal guardian and mandatory pre-test genetic counselling as per UAE Federal Decree-Law No. 41 of 2024.

Frequently Asked Questions & Clinical Guidance
1. What is the NNT gene and why is this NGS test recommended for suspected Glucocorticoid Deficiency Type 4?
The NNT gene encodes nicotinamide nucleotide transhydrogenase, a mitochondrial enzyme critical for NADPH regeneration and adrenal steroidogenesis, and pathogenic biallelic variants cause autosomal recessive Familial Glucocorticoid Deficiency Type 4. This NGS-based genetic test is the gold-standard confirmatory diagnostic tool when a patient presents with unexplained hypoglycaemia, hyperpigmentation, failure to thrive, and low serum cortisol with markedly elevated ACTH levels. Unlike single-gene Sanger sequencing, our NGS approach covers all coding exons, intron-exon boundaries, and detects CNVs that may be missed by conventional methods. Early molecular diagnosis enables timely initiation of life-saving glucocorticoid replacement and genetic counselling for family planning.
يقوم تحليل الجين NNT بتقييم الطفرات المسببة لنقص القشرانيات السكرية الوراثي النوع الرابع، وهو مرض وراثي متنحي نادر يؤثر على الغدة الكظرية، مما يساعد في بدء العلاج التعويضي بالكورتيزون في الوقت المناسب.
2. How should I prepare for the NNT Gene Genetic Test and what sample types are accepted?
No fasting or medication adjustments are required; however, a mandatory pre-test genetic counselling session is scheduled to construct a detailed three-generation pedigree chart before sample collection. We accept three sample types: (1) 3–5 mL of whole blood collected in EDTA (lavender-top) tubes, (2) extracted genomic DNA at a minimum concentration of 50 ng/µL with A260/A280 ratio between 1.8–2.0, or (3) one drop of blood on an FTA Card (Whatman FTA or equivalent), which is ideal for paediatric patients and remote home collection. Blood samples must be refrigerated at 2–8°C and transported within 24 hours. FTA cards are stable at ambient temperature. Our VIP Mobile Phlebotomy team serves all seven Emirates from 8:00 AM to 11:00 PM with full cold-chain logistics.
تُقبل ثلاث أنواع من العينات: الدم الكامل، الحمض النووي المستخلص، أو نقطة دم على بطاقة FTA، مع جلسة استشارة وراثية إلزامية قبل الفحص لرسم شجرة العائلة.
3. How reliable is this NGS test and what do the results mean for my clinical management?
This ISO 9001:2015 accredited NGS assay achieves 99.9% diagnostic sensitivity with 100× minimum read depth across all coding regions of the NNT gene, delivering clinically actionable results in 3 to 4 weeks. Results are reported using 2026 ACMG/AMP variant classification: Pathogenic, Likely Pathogenic, Variant of Uncertain Significance (VUS), Likely Benign, or Benign. A positive (Pathogenic/Likely Pathogenic) result confirms the molecular diagnosis and guides immediate endocrinology referral for glucocorticoid ± mineralocorticoid replacement. A VUS result requires familial segregation testing and periodic reanalysis. A negative result does not exclude adrenal insufficiency from other genetic causes (e.g., MC2R, MRAP, STAR, CYP11A1 mutations). All results include complimentary telephonic clinical guidance with a DHA-certified molecular pathologist to ensure accurate interpretation and next-step planning.
تبلغ الحساسية التشخيصية للفحص 99.9%، وتُصنف النتائج وفقاً لمعايير ACMG/AMP لعام 2026، مع استشارة سريرية هاتفية مجانية بعد ظهور النتائج.
