Accurate molecular diagnosis for a rare urea cycle disorder—providing answers for families and guidance for treatment.
HHH Syndrome, also known as Triple H Syndrome or Hyperornithinemia-Hyperammonemia-Homocitrullinuria, is a rare inherited metabolic disorder that affects the urea cycle—the process by which the body removes excess nitrogen. For families in the UAE facing unexplained neurological symptoms or metabolic crises in a child, confirming a diagnosis is the first step toward effective management. The HHH Syndrome DNA Test at DNA Labs UAE offers definitive genetic analysis to identify mutations in the SLC25A15 gene, providing clarity for patients, families, and their healthcare providers.
What is HHH Syndrome (Triple H) and Its Genetic Test?
HHH Syndrome is a rare autosomal recessive disorder caused by mutations in the SLC25A15 gene. This gene provides instructions for a protein (ornithine translocase) that is essential for the urea cycle to function properly. When this protein is deficient, three key abnormalities occur:
-
Hyperornithinemia: Elevated levels of the amino acid ornithine in the blood.
-
Hyperammonemia: Elevated ammonia levels, which can be toxic, especially to the brain.
-
Homocitrullinuria: Excessive homocitrulline excreted in the urine.
The HHH Syndrome DNA Test is a molecular genetic analysis that sequences the SLC25A15 gene to identify disease-causing mutations. This confirms the diagnosis at the genetic level, allowing for targeted medical management, family carrier testing, and informed family planning.
Who is This Test For?
This test is essential for individuals and families in the UAE who are navigating the challenges of this rare condition.
-
Symptomatic Children and Adults: Individuals (often presenting in childhood) with symptoms such as recurrent vomiting, lethargy, confusion, developmental delay, seizures, or episodes of acute encephalopathy triggered by high-protein meals or illness.
-
Individuals with Abnormal Metabolic Findings: Those with biochemical test results suggesting a urea cycle disorder, including elevated plasma ammonia, elevated ornithine, or elevated urine homocitrulline.
-
Families with a Known History: Families who have a child diagnosed with HHH Syndrome and wish to test other children or determine carrier status for informed family planning.
-
Couples Planning Marriage or Pregnancy: For couples with a family history of the disorder, carrier testing can determine their risk of having an affected child.
-
Individuals with Unexplained Neurological Symptoms: In some cases, milder forms of the disorder can present later in life with intermittent neurological issues.
What You Will Learn / Discover
Your comprehensive HHH Syndrome DNA test report provides definitive answers at the molecular level.
-
Confirmation of Diagnosis: Identifies the specific genetic mutation(s) in the SLC25A15 gene responsible for the condition, confirming or ruling out HHH Syndrome.
-
Carrier Status: For family members, the test can determine if they are asymptomatic carriers of the condition (having one copy of the mutated gene), which is crucial for reproductive planning.
-
Informed Medical Management: A confirmed genetic diagnosis allows physicians to tailor treatment, which may include protein-restricted diets, ammonia-scavenging medications, and supplementation with arginine or citrulline.
-
Prognostic Guidance: Understanding the specific genetic mutation can, in some cases, provide insight into the potential severity and progression of the disorder.
-
Family Planning Options: For couples who are both carriers, the test results enable informed decisions, including prenatal diagnosis (CVS or amniocentesis) or preimplantation genetic diagnosis (PGD) for future pregnancies.

Important Disclaimer
The HHH Syndrome DNA Test is a molecular genetic test intended for diagnostic and informational purposes. It is not a substitute for a physical examination or consultation with a qualified healthcare professional.
Test results should be interpreted by a specialist physician, such as a metabolic specialist, neurologist, or genetic counselor, in the context of the individual’s full clinical presentation, family history, and other laboratory findings. This test is not intended to diagnose all possible causes of hyperammonemia or neurological symptoms. DNA Labs UAE strongly advises all customers to discuss their results with a healthcare professional.
Frequently Asked Questions
1. What is the price of the HHH Syndrome DNA test in the UAE?
The price for the HHH Syndrome (SLC25A15) DNA test at DNA Labs UAE is 1,550 AED. This includes the genetic analysis, sample collection, and a detailed report.
2. What is the full form of HHH Syndrome?
HHH stands for Hyperornithinemia-Hyperammonemia-Homocitrullinuria syndrome. It is also sometimes called Triple H Syndrome.
3. What are the common symptoms of HHH Syndrome?
Symptoms can vary widely but often include vomiting, refusal to eat, lethargy, developmental delay, intellectual disability, seizures, and episodes of confusion or coma (acute encephalopathy) often triggered by high-protein meals or illness. Some individuals may have milder, intermittent symptoms.
4. How is HHH Syndrome diagnosed?
Diagnosis typically begins with biochemical testing, including plasma ammonia, plasma amino acids (looking for elevated ornithine), and urine organic acids (looking for homocitrulline). The DNA test is used to confirm the diagnosis by identifying mutations in the SLC25A15 gene.
5. What is the normal range for an HHH test?
Biochemical “normal ranges” vary by age and laboratory. However, the HHH DNA test is not about ranges; it is a qualitative test looking for the presence or absence of disease-causing mutations in the SLC25A15 gene. A “normal” or negative result means no pathogenic mutations were found.
6. How is HHH Syndrome treated?
Treatment focuses on managing ammonia levels and may include a protein-restricted diet, ammonia-scavenging medications (like sodium benzoate or sodium phenylbutyrate), and supplementation with arginine or citrulline. Treatment must be managed by a specialist metabolic physician.
7. Is HHH Syndrome curable?
HHH Syndrome is a genetic condition, and there is currently no cure. However, with early diagnosis and careful management, symptoms can be controlled, and many individuals can lead healthier lives with improved outcomes.
8. Is the blood sample collection method Halal?
Yes, the blood draw is a standard medical procedure performed by licensed professionals using sterile, single-use equipment. It is universally acceptable with no religious restrictions.
9. How is this test different from the standard premarital screening in the UAE?
The mandatory premarital screening in the UAE focuses on common genetic blood disorders (like sickle cell and thalassemia) and infectious diseases. HHH Syndrome is a rare disorder and is not part of that standard panel. This test is a specialized, optional genetic test for individuals with specific clinical indications or family history.
10. Can this test be used for prenatal diagnosis?
Yes, once a pathogenic mutation is identified in a family, prenatal testing (via CVS or amniocentesis) or preimplantation genetic diagnosis (PGD) can be performed. Please discuss these options with your genetic counselor and contact us for special arrangements.
11. How long does it take to get the results?
Results for this specialized genetic test are typically available within a specified timeframe from when your sample is received at our laboratory. You will be notified as soon as your secure report is ready.
12. Will my health insurance cover the cost?
Coverage for genetic testing for rare diseases varies by insurance policy. Many insurers may require pre-authorization and a referral from a specialist. DNA Labs UAE provides a detailed invoice that you can submit to your insurance company for potential reimbursement. Please check your specific policy.
