Symptoms and Testing information for ATP1A2 Gene Alternating hemiplegia of childhood type 1 Genetic Test

Alternating Hemiplegia of Childhood (AHC) is a rare neurological disorder that typically manifests in infancy or early childhood. It is characterized by recurrent episodes of paralysis on one side of the body (hemiplegia), which can switch sides. These episodes can last from minutes to days. The ATP1A2 gene has been identified as one of the genetic contributors to this condition, specifically associated with Alternating Hemiplegia of Childhood type 1. Understanding the symptoms and undergoing genetic testing can be crucial for the diagnosis, management, and treatment of this condition.

Symptoms of ATP1A2 Gene Alternating Hemiplegia of Childhood Type 1

The symptoms of AHC type 1 due to mutations in the ATP1A2 gene can vary widely among individuals but generally include:

  • Paroxysmal Episodes: Sudden onset of hemiplegia affecting either side of the body. These episodes can also involve the face and are often triggered by environmental factors such as changes in temperature, water exposure, or physical activity.
  • Seizures: Many individuals with AHC type 1 experience various types of seizures, which can worsen during hemiplegic episodes.
  • Developmental Delays: Delays in reaching developmental milestones such as walking and talking are common due to the neurological impact of the disorder.
  • Dystonia: Involuntary muscle contractions that result in abnormal postures or repetitive movements.
  • Other Neurological Abnormalities: These can include ataxia (lack of muscle coordination), choreoathetosis (involuntary movements of the limbs), and nystagmus (rapid, uncontrolled eye movements).

It’s important to note that the severity and frequency of these symptoms can vary significantly from person to person. Some individuals may experience mild symptoms, while others may have severe and disabling manifestations.

Genetic Test for ATP1A2 Gene Alternating Hemiplegia of Childhood Type 1

Genetic testing for AHC type 1 involves analyzing the ATP1A2 gene for mutations known to cause the disorder. This test is crucial for confirming the diagnosis, especially in cases where the clinical presentation is unclear. Additionally, understanding the genetic basis of the disorder can help in predicting its course, guiding treatment decisions, and providing genetic counseling for affected families.

DNA Labs UAE offers a comprehensive ATP1A2 Gene Alternating Hemiplegia of Childhood Type 1 Genetic Test aimed at identifying mutations in the ATP1A2 gene. The test is performed using a blood sample and employs advanced sequencing technologies to ensure accurate results.

Test Cost

The cost of the ATP1A2 gene test at DNA Labs UAE is 4400 AED. While the price may seem high, it’s important to consider the comprehensive nature of the test and the invaluable information it provides for affected individuals and their families. Early diagnosis and intervention can significantly improve the quality of life for those living with AHC type 1.


Alternating Hemiplegia of Childhood type 1 is a challenging condition that affects not only the individuals diagnosed but also their families. Understanding the symptoms and genetic underpinnings of the disorder is the first step toward effective management. Genetic testing, such as the ATP1A2 gene test offered by DNA Labs UAE, plays a pivotal role in this process, providing a definitive diagnosis and guiding treatment strategies.
