Glycine encephalopathy, also known as non-ketotic hyperglycinemia (NKH), is a rare genetic disorder characterized by an excess of glycine in the body’s tissues and fluids. This condition is typically associated with mutations in the genes responsible for the glycine cleavage system, a critical enzyme complex necessary for the metabolism of glycine. Among these genes, mutations in the SLC6A9 gene have been identified as one of the causes of glycine encephalopathy. However, a unique form of this condition exists where patients exhibit typical symptoms of glycine encephalopathy but have normal serum glycine levels. This form is specifically associated with mutations in the SLC6A9 gene.
Symptoms of SLC6A9 Gene Glycine Encephalopathy with Normal Serum Glycine
The clinical presentation of glycine encephalopathy with normal serum glycine due to SLC6A9 gene mutations can vary widely among affected individuals. However, common symptoms often include:
- Neurological impairment: This can range from mild to severe and may include developmental delay, intellectual disability, and hypotonia (decreased muscle tone).
- Seizures: A significant number of patients experience seizures, which can be difficult to manage.
- Behavioral abnormalities: Some individuals may display behavioral issues such as hyperactivity or irritability.
- Feeding difficulties: Infants with this condition often have trouble feeding due to poor sucking reflexes and hypotonia.
- Respiratory problems: Breathing irregularities can occur, sometimes leading to respiratory failure in severe cases.
It is crucial to note that the severity and combination of symptoms can vary significantly from one patient to another. Early diagnosis and intervention are key to managing the symptoms and improving the quality of life for those affected.
Genetic Testing for SLC6A9 Gene Glycine Encephalopathy with Normal Serum Glycine
Genetic testing plays a pivotal role in diagnosing glycine encephalopathy with normal serum glycine due to SLC6A9 gene mutations. DNA Labs UAE offers a comprehensive genetic test designed to identify mutations in the SLC6A9 gene, providing essential information for accurate diagnosis and management of the condition. The test involves analyzing the patient’s DNA to look for specific genetic alterations associated with the disorder.
The cost of the genetic test at DNA Labs UAE is 4400 AED. This investment covers the complete analysis and provides a detailed report that can guide treatment and management strategies tailored to the patient’s specific genetic makeup.
