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.

  • ✓Progressive vision loss
  • ✓Sensitivity to light (photophobia)
  • ✓Family history of Bietti crystalline corneoretinal dystrophy
  • ✓Suspicion of a rare inherited eye disorder
  • ✓Genetic counseling for families with affected members

In plain language

What this test helps you understand

This test helps identify individuals with mutations in the CYP4V2 gene, confirming a diagnosis of Bietti crystalline corneoretinal dystrophy or identifying carriers within a family.
The CYP4V2 Gene Bietti Crystalline Corneoretinal Dystrophy NGS Genetic DNA Test is a diagnostic tool used to identify genetic predispositions to Bietti crystalline corneoretinal dystrophy, a rare condition affecting the eye. This test employs Next-Generation Sequencing (NGS) technology to analyze the CYP4V2 gene, which is linked to this disorder. Understanding your genetic information is important for the early diagnosis and management of potential eye conditions. This test specifically looks for mutations within the CYP4V2 gene that can cause Bietti crystalline corneoretinal dystrophy. Detecting these mutations allows healthcare providers to offer patients a better understanding of their risk for developing this eye condition. Results from the test provide information about the presence of mutations in the CYP4V2 gene. A genetic counselor can help interpret these results and explain their significance for your health and your family's health.
