Hearing loss can run in families, though you won’t always be as susceptible as your relatives. At Killean Audiology & Hearing Aid Centers, our team of doctoral-level audiologists can evaluate your hearing in the context of your family history, at seven offices that include Clinton, Davenport, Dubuque and Moline. If hearing loss is a known condition in your family, early testing and protective habits can help you preserve your hearing and address changes sooner.
Why Is Some Hearing Loss Considered Genetic?
Some hearing loss is considered genetic because it’s caused by changes in genes that affect how the ear develops or functions. Most genetic hearing loss is sensorineural, meaning it involves the hair cells of the inner ear or the auditory nerve. It may be present at birth or develop later in life.
Genetic hearing loss falls into two main groups. Nonsyndromic hearing loss accounts for about 70% of genetic cases and occurs without other medical symptoms. Syndromic hearing loss makes up the remaining 30% and occurs alongside other health conditions, such as Usher, Pendred, and Waardenburg syndromes.
Can Parents With Normal Hearing Pass On Genetic Hearing Loss?
Parents with normal hearing can pass on genetic hearing loss, and a child’s overall likelihood depends on the inheritance pattern of the specific gene involved. Depending on the pattern, a child’s chance may range from no risk to 50% or higher.
The main inheritance patterns include:
- Autosomal dominant: Only one changed gene from one parent is needed, giving each child a 50% chance of inheriting the condition.
- Autosomal recessive: Both parents carry one changed gene without having hearing loss themselves, giving each child a 25% chance of inheriting the condition.
- X-linked: The changed gene is on the X chromosome, so males are more likely to be affected, while females are often carriers.
- Mitochondrial: The condition is passed only by the mother and can affect all of her children.
Autosomal recessive inheritance accounts for about 80% of nonsyndromic genetic hearing loss, which explains why most infants with hearing loss are born to parents with normal hearing. Even among siblings and cousins, severity and age of onset can vary from one person to another.
When Do Signs of Inherited Hearing Loss Usually Begin?
Signs of inherited hearing loss may begin at birth, during childhood, or later in adulthood. Some forms are congenital and identified through newborn hearing screening, while others are progressive and develop gradually over years or decades.
Congenital hearing loss affects up to three in every 1,000 babies, and inherited genetic factors contribute to about 60% of hearing loss in infants. In young children, signs may include not reacting to loud sounds, not turning toward voices, or delays in speech and language development.
Because later-onset genetic hearing loss often develops slowly, it can be easy to overlook. Adults may notice:
- Difficulty following conversations in noisy places
- Asking others to repeat themselves
- Turning up the television or phone volume
- Ringing or buzzing in the ears
Gradual changes can go unnoticed by the person experiencing them, so family members are often the first to recognize them.
Who Should Get a Baseline Hearing Test in Clinton or Davenport?
Anyone who notices changes in their hearing should get tested right away, and people with a family history of hearing loss may benefit from a baseline test and regular evaluations even before symptoms appear.
Almost all hospitals screen newborns for hearing loss within the first few days of life. Children who pass newborn screening but have a family history of hearing loss may still benefit from monitoring, since some genetic forms develop later.
For adults, a baseline hearing evaluation provides a reference point for tracking changes over time. Our audiologists can perform comprehensive hearing tests, discuss your family history, and recommend how often you should return for follow-up testing. When a genetic cause is suspected, they may recommend a referral for genetic counseling or testing. Currently, no genetic test can predict whether a person will develop age-related hearing loss, which makes regular hearing evaluations especially important.
How Can You Lower Your Risk When Hearing Loss Runs in the Family?
When hearing loss runs in the family, you can lower your risk of further damage by limiting noise exposure, using hearing protection, reviewing medications with your healthcare providers, managing your overall health, and scheduling regular hearing evaluations.
Because some genes can make the inner ear more vulnerable to damage, avoiding additional strain is especially important. Wearing earplugs or earmuffs around loud equipment, concerts, or firearms and keeping headphone volume at moderate levels can reduce noise exposure. Some medications can affect hearing, so let your healthcare providers know about a family history of hearing loss before starting new prescriptions.
Overall health also plays a role. Conditions such as high blood pressure, heart disease, and diabetes may increase the risk of hearing loss, so managing these conditions supports long-term hearing health.
When hearing loss does develop, our audiologists can recommend options such as hearing aids and track changes over time to adjust your care as needed.
Schedule a Hearing Test at Killean Audiology & Hearing Aid Centers
If hearing loss runs in your family, a hearing evaluation is the natural first step. That first test establishes a baseline and helps determine whether immediate treatment or continued monitoring is the better course.
