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.

  • ✓Family history of posterior polar cataracts
  • ✓Early onset cataracts
  • ✓Suspected hereditary cataract
  • ✓Genetic counseling for cataract risk
  • ✓Pre-implantation genetic diagnosis (PGD) planning
02

In plain language

What this test helps you understand

Identifies genetic mutations in the CRYAB gene associated with posterior polar cataracts. Helps assess individual risk and informs family screening.
This genetic test analyzes the CRYAB gene, which is linked to the development of cataracts, specifically the posterior polar type. Using Next Generation Sequencing (NGS) technology, the test identifies mutations in the CRYAB gene that may increase the risk of developing cataracts. Understanding your genetic predisposition can help in early monitoring and management. This test is particularly relevant for individuals with a family history of cataracts or those experiencing early onset cataracts.

A simple process

What happens next?

You do not have to navigate the test alone. We help you move from question to next step.

1

Speak with us

We check the test and answer your questions before collection.

2

Give your sample

Choose home collection or a coordinated hub visit in Kenya. We explain whether this test uses a cheek swab or blood draw.

3

Understand your report

A counselor helps you understand the result and the next steps.

05

Choose your collection

Home collection or a lab visit

We will explain the sample, preparation, and next steps before anything is collected.

Home collection

Choose a coordinated visit at home or another convenient location. Our team confirms the appointment and sample requirements in advance.

Lab or hub visit

PrivacyYour sample and report are handled confidentially. Ask the team how your information is stored and shared.
This test only analyzes the CRYAB gene. Cataracts can have other genetic and non-genetic causes. A negative result does not completely rule out a genetic predisposition. Results may be inconclusive in some cases.

What common result terms mean

PositiveA finding was identified. Your clinician or counselor will explain what it means for your care.
NegativeThe specific finding tested for was not identified. It does not rule out every possible cause.
VUSA variant was found, but current evidence is not enough to classify it. Your counselor can explain follow-up.
07

Questions people ask

Frequently asked questions

The CRYAB gene provides instructions for making a protein called small heat shock protein alpha-B crystallin. This protein helps keep the lens of the eye clear. Mutations in this gene can lead to cataracts.
This test is recommended for individuals with a family history of posterior polar cataracts, those with early onset cataracts, or those seeking to understand their genetic risk.
A positive result indicates the presence of a mutation in the CRYAB gene associated with posterior polar cataracts. Discuss the implications with your doctor or a genetic counselor.
Yes, genetic counseling is highly recommended to help understand the test results, their implications for you and your family, and potential management options.
This test identifies genetic risk factors for cataracts but does not diagnose the condition itself. A clinical eye examination is necessary for diagnosis.
