Symptoms and Testing information for CHN1 Gene Duane Retraction syndrome Genetic Test

Duane Retraction Syndrome (DRS) is a congenital eye movement disorder that limits the ability of the eye to move outward toward the ear (abduction) and, in some cases, also limits movement inward toward the nose (adduction). This condition is often associated with the CHN1 gene, and understanding its symptoms is crucial for early diagnosis and management. DNA Labs UAE offers a comprehensive genetic test for the CHN1 gene to help identify this syndrome, priced at 4400 AED.

Symptoms of CHN1 Gene Duane Retraction Syndrome

The symptoms of Duane Retraction Syndrome related to the CHN1 gene mutation can vary from mild to severe and typically present in early childhood. It is important for parents and healthcare providers to be aware of these symptoms to ensure timely diagnosis and intervention. Key symptoms include:

  • Limitation in Eye Movement: The most common and noticeable symptom is a restriction in moving the eye outward or inward. This can affect one or both eyes.
  • Eye Retraction: When attempting to move the eye inward, the eye may pull into the socket, causing the eyelids to narrow and the eye to appear smaller.
  • Abnormal Head Postures: Individuals with DRS may adopt an abnormal head position, such as turning or tilting the head in a specific direction to compensate for the limited eye movement and improve their field of vision.
  • Strabismus: Misalignment of the eyes, commonly known as crossed eyes, may occur as the eyes do not move together in a coordinated manner.
  • Blinking to Move the Eye: Some individuals may develop a unique phenomenon known as “fistula phenomenon,” where blinking triggers eye movement.

Early detection of these symptoms can lead to a more comprehensive understanding of the individual’s condition and the development of a tailored management plan.
