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.

  • ✓Family history of congenital cataracts
  • ✓Early onset cataracts
  • ✓Suspected genetic predisposition to cataracts
  • ✓Genetic counseling for families with cataracts
  • ✓Diagnosis confirmation in cases of congenital cataracts

In plain language

What this test helps you understand

Identifies genetic mutations in the TDRD7 gene linked to congenital cataracts, aiding in diagnosis, risk assessment, and family planning.
The TDRD7 Gene Cataract Autosomal Recessive Congenital Type 4 NGS Genetic DNA Test is a specialized genetic analysis designed to detect mutations within the TDRD7 gene. These mutations are known to be associated with congenital cataracts, a condition where clouding of the lens is present at birth or develops shortly after. Early diagnosis and treatment are crucial for managing congenital cataracts and preventing significant visual impairment. This test is particularly valuable for individuals with a family history of cataracts, helping to identify genetic risks and inform clinical management decisions.

This test utilizes Next Generation Sequencing (NGS) technology to provide a detailed analysis of the TDRD7 gene. NGS allows for the precise identification of genetic variations that may contribute to the development of cataracts. Understanding the genetic basis of cataracts can help in making informed decisions about treatment and potential preventative measures.

Discussing the results with a healthcare provider is essential for proper interpretation and to understand the implications for your health and family.

Questions people ask

Frequently asked questions

A congenital cataract is a clouding of the lens of the eye that is present at birth or develops shortly after. It can affect vision if not treated.
Individuals with a family history of congenital cataracts, those experiencing early onset cataracts, or those seeking genetic counseling related to cataracts may benefit from this test.
A positive result indicates that a mutation associated with congenital cataracts was found in the TDRD7 gene. Discuss the implications with your healthcare provider.
A negative result suggests that no mutations associated with congenital cataracts were found in the TDRD7 gene. Other genetic or non-genetic causes may be involved.
A sample can be collected as a blood draw, extracted DNA, or a single drop of blood on an FTA card.
Results are typically available within 3 to 4 weeks, but this may vary. Confirm with the laboratory before booking.
