Symptoms and Testing information for C21orf2 Gene Cone-rod dystrophy C21orf2 related Genetic Test

Cone-rod dystrophy is a group of inherited eye disorders that affect the retina. One of the genetic causes of this condition has been identified as mutations in the C21orf2 gene. Understanding the symptoms and seeking early diagnosis through genetic testing can significantly impact the management and quality of life of individuals affected by this condition. DNA Labs UAE offers a comprehensive genetic test specifically for the C21orf2 gene-related cone-rod dystrophy, helping families and individuals gain crucial insights into their genetic makeup and manage the condition more effectively.

Symptoms of C21orf2 Gene Cone-rod Dystrophy

Cone-rod dystrophy affects the cone and rod cells in the retina, leading to a progressive loss of vision. Symptoms typically begin in childhood or adolescence and may include:

  • Decreased visual acuity: Difficulty in seeing details clearly, which cannot be corrected with glasses or contact lenses.
  • Loss of color vision: Difficulty in distinguishing colors, particularly in dim light.
  • Photophobia: Increased sensitivity to light and discomfort in bright environments.
  • Central vision loss: Over time, individuals may experience a loss in their central field of vision, making tasks like reading, driving, and recognizing faces challenging.
  • Night blindness: Difficulty seeing in low light conditions or in the dark.

As the condition progresses, the peripheral vision may also deteriorate, leading to tunnel vision or, in severe cases, complete blindness.

C21orf2 Related Genetic Test

DNA Labs UAE offers a genetic test for the C21orf2 gene to identify mutations associated with cone-rod dystrophy. This test is crucial for individuals with a family history of the condition or those experiencing symptoms suggestive of cone-rod dystrophy. The genetic test involves a simple blood draw or cheek swab, with results typically available within a few weeks. The test cost is 4400 AED.

Benefits of Genetic Testing

Undergoing genetic testing for the C21orf2 gene has several benefits:

  • Early Diagnosis: Identifying the condition early can help in managing symptoms and slowing the progression of vision loss.
  • Personalized Management Plans: Understanding the genetic cause of cone-rod dystrophy allows for more personalized and effective management strategies.
  • Family Planning: For families with a history of the condition, genetic testing can provide valuable information for future family planning decisions.
  • Research Opportunities: Participants may have the opportunity to contribute to research studies aimed at finding new treatments or understanding the condition better.


Cone-rod dystrophy related to the C21orf2 gene significantly impacts individuals and their families. However, through early diagnosis and personalized management strategies, those affected can lead a better quality of life. DNA Labs UAE is committed to providing comprehensive and reliable genetic testing services, including the C21orf2 gene-related cone-rod dystrophy genetic test.
