Many people with hearing loss may have an idea of what caused it, like loud noises or a head injury. However, some wonder if genetics (inherited traits) play a role. The answer is yes, genetic factors can contribute to hearing loss, but it’s not always easy to explain exactly how.
Genetic hearing loss can be different for each person. There are many changes in our DNA that can cause hearing loss, and they can affect things like how severe the loss is, when it starts, how it changes over time, and whether it’s linked to other health problems. Hearing loss caused by genetics can be part of a syndrome (where other body systems are affected) or not. Also, factors like kidney function, exposure to loud sounds, use of certain medications, and age can make a genetic hearing loss worse.
For infants diagnosed with hearing loss, it’s important to not only see an ear specialist but also consider genetic testing and counseling. This can help understand the cause of the hearing loss and guide parents in making decisions for the child’s care.
If you have concerns about your hearing or genetic hearing loss, audiologists can help answer your questions and make sure you get the right care.
