Symptoms and Testing information for GLRA1 Gene Hyperekplexia Genetic Test

Hyperekplexia, also known as startle disease, is a rare genetic disorder characterized by an exaggerated startle reflex. This condition can lead to significant physical and psychological challenges for affected individuals. The GLRA1 gene plays a crucial role in the normal functioning of inhibitory glycine receptors in the brain. Mutations in the GLRA1 gene can disrupt these processes, leading to the symptoms associated with hyperekplexia. Recognizing the symptoms early can lead to a timely diagnosis and appropriate management of the condition. DNA Labs UAE offers a comprehensive genetic test for hypereklexia through the analysis of the GLRA1 gene.

Symptoms of GLRA1 Gene Hyperekplexia

The symptoms of hyperekplexia caused by GLRA1 gene mutations can vary significantly among individuals but typically include:

  • Exaggerated Startle Response: This is the hallmark symptom of hyperekplexia, where individuals exhibit an excessive startle reaction to unexpected stimuli.
  • Stiffness: Muscle stiffness, especially in neonates, can be a sign of hyperekplexia. This stiffness may improve with movement.
  • Temporary Apnea: The startle response can sometimes cause brief periods of apnea (cessation of breathing) in infants.
  • Developmental Delays: In some cases, the condition may lead to developmental delays, particularly if seizures are a symptom.
  • Nocturnal Myoclonus: Some individuals may experience episodes of sudden, involuntary muscle contractions during sleep.

It’s important to note that the severity and presence of these symptoms can vary, and not all individuals with a GLRA1 gene mutation will experience all these symptoms.

GLRA1 Gene Hyperekplexia Genetic Test

DNA Labs UAE provides a specialized genetic test for hyperekplexia through the analysis of the GLRA1 gene. This test is crucial for individuals exhibiting symptoms of hyperekplexia or those with a family history of the condition. The test involves collecting a DNA sample, usually through a blood draw or a cheek swab, which is then analyzed in our state-of-the-art laboratory.

Test Cost

The cost of the GLRA1 gene hyperekplexia genetic test at DNA Labs UAE is 4400 AED. This cost includes the full analysis of the GLRA1 gene to identify any mutations that may be responsible for the symptoms of hyperekplexia. Our team of genetic counselors is also available to provide guidance and support throughout the testing process and to help interpret the results.


Understanding the symptoms of GLRA1 gene hyperekplexia is the first step towards a timely diagnosis and effective management of the condition. The genetic test offered by DNA Labs UAE plays a crucial role in identifying the underlying genetic cause of hyperekplexia, enabling individuals and their families to take informed steps towards managing the condition.
