HHH Syndrome Hyperornithinemia – Hyperammonemia – Homocitrullinuria Syndrome Test
Test Cost: AED 1640.0
Symptoms:
- Neurological problems
- Developmental delay
- Intellectual disability
- Episodes of hyperammonemia
Diagnosis:
The HHH syndrome, also known as Hyperornithinemia-Hyperammonemia-Homocitrullinuria syndrome, is a rare metabolic disorder that affects the metabolism of the amino acid ornithine. This condition is caused by mutations in the SLC25A15 gene, which is responsible for the production of a protein called mitochondrial ornithine transporter.
The HHH syndrome test is a diagnostic test used to confirm the presence of this condition. It typically involves several steps:
- Clinical evaluation: A healthcare professional will review the patient’s medical history and symptoms to assess if they are consistent with HHH syndrome.
- Blood tests: Blood samples are taken to measure the levels of ornithine, ammonia, and homocitrulline. Elevated levels of these substances may indicate HHH syndrome.
- Urine tests: Urine samples are collected to measure the levels of orotic acid and homocitrulline. Increased levels of these substances may also indicate HHH syndrome.
- Genetic testing: Genetic testing is performed to identify mutations in the SLC25A15 gene. This can be done through DNA sequencing or other molecular techniques.
- Liver biopsy (in some cases): In certain situations, a liver biopsy may be performed to assess the severity of liver damage caused by HHH syndrome.
The HHH syndrome test should be performed by a qualified healthcare professional with experience in diagnosing and managing metabolic disorders. Genetic counseling may also be recommended to discuss the inheritance pattern and implications for family members.
