01

Start with fit

Is this the right test for you?

The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.

  • ✓Symptoms of progressive vision loss, including night blindness or loss of color vision.
  • ✓Family history of cone-rod dystrophy or other inherited retinal diseases.
  • ✓Diagnosis of cone-rod dystrophy requiring genetic confirmation.
  • ✓Genetic counseling for individuals or families with suspected C21orf2-related vision loss.
  • ✓Assessing genetic risk in individuals with related eye conditions.

In plain language

What this test helps you understand

This test helps identify specific genetic mutations in the C21orf2 gene linked to cone-rod dystrophy. It aids in confirming a diagnosis, understanding the genetic basis of the condition, and potentially informing management strategies. It can also be used for genetic counseling within families.
The C21orf2 Gene Cone-Rod Dystrophy test is a genetic analysis designed to detect mutations within the C21orf2 gene. This gene is known to be associated with a specific type of inherited vision loss called cone-rod dystrophy. This condition affects both cone cells (responsible for color vision and sharp detail) and rod cells (responsible for night vision) in the retina.

This test utilizes advanced Next Generation Sequencing (NGS) technology to examine the C21orf2 gene for variations that may cause or contribute to the development of cone-rod dystrophy. Understanding these genetic changes can be crucial for diagnosis, prognosis, and management of the condition.

This test is particularly relevant for individuals with symptoms suggestive of cone-rod dystrophy or those with a family history of similar eye conditions. Discussing your concerns with a healthcare provider is the first step.

Questions people ask

Frequently asked questions

Cone-rod dystrophy is an inherited eye disorder that affects the retina, causing progressive vision loss. It impacts both cone cells (color and detail vision) and rod cells (night vision).
Individuals experiencing symptoms like night blindness or color vision loss, or those with a family history of cone-rod dystrophy, should discuss this test with their doctor.
The test involves analyzing a sample of your blood or DNA to look for specific changes (mutations) in the C21orf2 gene.
Results should be discussed with a healthcare provider or genetic counselor who can explain the findings in relation to your health history and family background.
Yes, genetic counseling before and after testing is highly recommended to understand the implications of the test and its results.
