What's this test for?

This test is ideal if you or a family member have unexplained hearing loss that isn't linked to an infection, injury, or noise exposure. It's especially useful for parents of a child diagnosed with sensorineural hearing loss when doctors suspect a genetic cause. Identifying a genetic deletion can help explain why the hearing loss happened and whether it may affect other family members.

What's included in this test?

This test looks specifically for deletions in the GJB6 gene, one of the genetic changes linked to non-syndromic sensorineural hearing loss. Finding a deletion here matters because it can confirm a genetic cause for hearing loss that might otherwise remain unexplained, and it helps clarify inheritance patterns for future children.

What happens after I get my results?

Your results will be available in your account, with an explanation of what a positive or negative finding means for the GJB6 gene deletion. If a deletion is found, next steps typically include genetic counseling resources and discussing hearing support options such as hearing aids or further evaluation. Since this is a one-time genetic test, retesting isn't usually needed, but you can keep the report on file for future family planning or medical reference. The standard lab report is downloadable from your account at any time, and you can revisit it later through the trends feature.

How can I naturally support hearing health?

While a genetic deletion itself can't be changed through lifestyle habits, protecting your remaining hearing is still valuable. Avoid prolonged exposure to loud noises and use ear protection in noisy environments like concerts or power tools. Eating a diet rich in antioxidants (found in fruits and vegetables) and omega-3 fatty acids may support overall ear health, and staying active can improve blood flow to the inner ear.

When will I get my results?

Results are typically ready within about 7 days after your sample is processed at the lab. You'll receive a notification once your results are posted to your secure account. Genetic tests like this one can take a bit longer than routine bloodwork because of the specialized analysis involved.

Who should consider this test?

This test is a good fit for individuals with sensorineural hearing loss of unknown cause, especially when it appeared early in life. Parents with a family history of hearing loss, or those planning to have children and wanting to understand inherited risks, may also want to consider it. It's commonly used alongside other genetic hearing loss tests, like Connexin 26, for a fuller picture.

What symptoms indicate I may need this test?

Signs that may point to a genetic hearing loss cause include hearing loss present from birth or early childhood, hearing loss that runs in the family, or hearing loss with no clear cause like illness or noise exposure. Gradual or sudden hearing decline without an obvious trigger is another reason to consider genetic testing. If a newborn hearing screening comes back abnormal, this test may help identify why.

What is the GJB6 gene and why does it matter?

The GJB6 gene provides instructions for a protein that helps cells in the inner ear communicate properly, which is essential for normal hearing. When part of this gene is missing (a deletion), it can disrupt that communication and lead to sensorineural hearing loss. Understanding this gene's role helps explain one of the more common genetic causes of inherited deafness.

What does a positive result mean?

A positive result means a deletion was found in your GJB6 gene, which is a known genetic cause of sensorineural hearing loss. This doesn't change existing hearing but confirms a genetic explanation, which can be helpful for family planning and understanding risk for future children. It's often looked at together with results from Connexin 26 testing since the two genes are closely related.

What should I do if my results are abnormal?

If a deletion is found, it's a good idea to explore genetic counseling resources to understand what it means for you and your family. Consider testing other close family members who may also carry the same genetic change. For hearing support, look into options like hearing aids, cochlear implants, or early intervention programs, especially if the test was done for a young child.
