Inherited Hearing Loss

Your Result

You are not likely to be a carrier for GJB2-related hearing loss. https://www.mayoclinic.org//-/media/kcms/gbs/patient-consumer/images/2017/08/30/17/30/no-select.png No genetic variants found https://www.mayoclinic.org//-/media/kcms/gbs/patient-consumer/images/2017/08/30/17/03/carrier.png Carrier, no signs https://www.mayoclinic.org//-/media/kcms/gbs/patient-consumer/images/2017/08/30/17/14/likely.png Likely has GJB2-related hearing loss

Here's What You Need to Know

This test ruled out the most common variants in the GJB2 gene. It's unlikely your children will be born with GJB2-related hearing loss. Even though this test didn't identify any variants, there is a chance that you still could be a carrier. Your risk to still be a carrier depends on your race, ethnicity, and family history. GJB2 is not the only gene that is associated with nonsyndromic hearing loss. You may have a variant in a different gene that causes nonsyndromic hearing loss, that this test is not designed to detect.

Here's what you can do

For most people, there's nothing more to do based on this result. If you have a family history of inherited hearing loss, you may want to consider more comprehensive testing. What will more testing tell me? Contact Us with Questions
