Autosomal recessive nonsyndromic deafness 59 is a genetic condition that causes hearing loss without other health problems. People with this condition typically have congenital or early-childhood hearing loss that can range from mild to profound. It affects all genders and can appear in families with no prior history due to new gene changes. The condition itself is not life-threatening, and most people have a normal life span. Treatment focuses on hearing support like hearing aids, cochlear implants, and speech and language therapy.
Overview
Autosomal recessive nonsyndromic deafness 59Symptoms
Autosomal recessive nonsyndromic deafness 59 causes hearing loss without other health issues, often noticed at birth or early childhood. Early signs of Autosomal recessive nonsyndromic deafness 59 include not startling to loud sounds, delayed speech, and trouble hearing in noise.
Outlook and prognosis
Many people with autosomal recessive nonsyndromic deafness 59 develop stable, early-onset hearing loss that doesn’t affect other body systems. With timely hearing support—like hearing aids, cochlear implants, and communication therapy—children can develop language and adults stay engaged. Lifespan is typical, and family planning guidance is available.
Causes and risk factors
Autosomal recessive nonsyndromic deafness 59 stems from PJVK gene changes, inherited in an autosomal recessive pattern. Risk rises when both parents are carriers, especially with consanguinity; loud noise or ototoxic medicines don’t cause it but may worsen severity.
Genetic influences
Genetics are central to Autosomal recessive nonsyndromic deafness 59. Variants in both copies of the relevant gene cause the condition, while carriers typically have normal hearing. Family history, consanguinity, and specific ancestral backgrounds can influence risk patterns.
Diagnosis
Doctors suspect Autosomal recessive nonsyndromic deafness 59 from hearing test patterns and family history. Genetic diagnosis of Autosomal recessive nonsyndromic deafness 59 uses genetic panel testing; imaging of the inner ear may support findings or rule out other causes.
Treatment and drugs
Autosomal recessive nonsyndromic deafness 59 is usually managed with hearing technology and communication support tailored to hearing level. Options can include digital hearing aids, cochlear or middle-ear implants, and bone-anchored devices, plus auditory training and speech-language therapy. Regular hearing checks and school or workplace accommodations help many stay engaged and independent.
Symptoms
Day to day, hearing differences can affect how babies startle to noise and how children pick up speech. You might notice small changes at first—like turning up the volume, missing soft consonants, or struggling to follow speech in a busy room. This can be part of a genetic, non‑syndromic hearing difference known as autosomal recessive nonsyndromic deafness 59. Early features of autosomal recessive nonsyndromic deafness 59 often show up at birth or in early childhood and usually involve both ears.
Hearing differences are present at birth or start in the first years of life. Parents may notice no startle to loud noises or delayed babbling. In autosomal recessive nonsyndromic deafness 59, both ears are usually involved.
First words may come later, and speech can sound unclear. With early support like hearing devices and therapy, many children catch up well.
Understanding speech is much harder in busy or echoey places. People may do better in quiet one‑to‑one conversations. Teachers and family often notice this during classroom time or group meals.
Hearing loss can range from moderate to profound. With autosomal recessive nonsyndromic deafness 59, it may stay steady or slowly change over time. Regular hearing checks help track this.
How people usually first notice Autosomal recessive nonsyndromic deafness 59?
Many families first notice something is different when a baby with autosomal recessive nonsyndromic deafness 59 doesn’t startle to sudden sounds or doesn’t turn toward a parent’s voice, especially after the newborn hearing screen suggests a possible hearing loss. Doctors often confirm this early with repeat hearing tests and, in some cases, genetic testing that identifies changes in the related gene, while the child otherwise looks healthy and develops typically. If the newborn screen was missed or borderline, the first signs of autosomal recessive nonsyndromic deafness 59 may show up in early infancy as delayed babbling, fewer vocalizations, or not responding to name by around 6 to 9 months.
Types of Autosomal recessive nonsyndromic deafness 59
Autosomal recessive nonsyndromic deafness 59 is a genetic, non-syndromic form of hearing loss caused by variants in the PTPRQ gene, with features limited to hearing rather than other body systems. There are no widely accepted clinical subtypes or disease classes beyond the underlying gene variant itself, so “types of autosomal recessive nonsyndromic deafness 59” usually refers to how hearing loss presents across ages and severity. Symptoms don’t always look the same for everyone. Most people have sensorineural hearing loss that can range from moderate to profound, sometimes noticed in early childhood and occasionally later in life.
Single recognized form
This condition is considered one genetic entity linked to PTPRQ changes. Hearing loss severity and age at onset can vary from person to person.
What genetics can tell you about symptoms
Changes in the PCDH15 gene can disrupt inner ear hair cell links, leading to newborn or early-childhood hearing loss that’s usually severe to profound and present in both ears. Because it’s autosomal recessive, symptoms appear when two nonworking copies are inherited.
Causes and risk factors
Inherited changes in the PJVK (pejvakin) gene are the main genetic causes of autosomal recessive nonsyndromic deafness 59. It follows an autosomal recessive pattern, so a child needs two changed copies, one from each carrier parent. Family history and two carrier parents raise the chance, and the risk is higher when parents are blood relatives. Loud noise at work or high-volume music and some medicines that can harm hearing may worsen hearing but do not cause this condition. Some risks are modifiable (things you can change), others are non-modifiable (things you can’t).
Environmental and biological risk factors
People often want to know what, if anything, in the body or environment raises the chance of a child being born with Autosomal recessive nonsyndromic deafness 59. This section focuses on environmental and biological risk factors rather than early symptoms of Autosomal recessive nonsyndromic deafness 59. Doctors often group risks into internal (biological) and external (environmental). For this specific type of hearing difference, the main drivers are internal and present from very early development.
There is no evidence that common environmental exposures raise the chance of Autosomal recessive nonsyndromic deafness 59. Loud noise, infections, or certain medicines can cause hearing loss in general, but they are not known to cause this specific type.
Infections during pregnancy can lead to hearing loss in babies, but they have not been linked to this specific condition. Their presence does not increase the chance that this form of deafness will occur.
Prematurity, low oxygen at birth, or NICU care are associated with hearing loss in some newborns, but they are not known to trigger Autosomal recessive nonsyndromic deafness 59. This condition arises independent of delivery events.
Current studies do not show a clear link between either parent’s age and the likelihood of this condition. Most cases are not explained by age-related changes at conception.
Genetic risk factors
Autosomal recessive nonsyndromic deafness 59 (often called DFNB59) happens when both copies of the PJVK gene carry harmful changes passed down from each parent. Some risk factors are inherited through our genes. Because these changes are present from birth, early symptoms of autosomal recessive nonsyndromic deafness 59 often appear in infancy or early childhood, sometimes showing a pattern known as auditory neuropathy. Genetic risk is highest when both parents are carriers, when there is a family history, or when parents share recent ancestors.
PJVK gene changes: Harmful changes in both copies of the PJVK gene cause autosomal recessive nonsyndromic deafness 59. These changes reduce or stop a protein called pejvakin that helps inner-ear cells respond to sound.
Autosomal recessive pattern: A child is affected only if two nonworking copies are inherited, one from each parent. People with one changed copy are typically healthy carriers.
Carrier parents: When both parents carry a PJVK change, each pregnancy has a 25% (1 in 4) chance to be affected, a 50% (1 in 2) chance to be a carrier, and a 25% (1 in 4) chance to inherit no changes. Carrier status does not usually affect hearing.
Family history: If one child has this condition, the chance that future siblings are affected or are carriers is higher. Relatives may carry the same gene change without symptoms.
Consanguinity: Parents who are related by blood are more likely to share the same rare PJVK change. This raises the chance that a child will receive two changed copies.
Ancestry clusters: In some communities with shared ancestry, certain PJVK variants are more common. This can increase carrier rates and the likelihood of affected children.
Two different variants: Two different harmful PJVK changes, one on each gene copy, can also cause the condition. The specific combination can shape age at onset and severity.
Variant effects differ: Even with the same PJVK changes, severity can vary within a family. This likely reflects how other genes modify the effect.
New mutations: New PJVK changes can occur, but having two new changes arise in the same child is rare. Most affected children inherit one change from each parent.
Lifestyle risk factors
Lifestyle habits do not cause this condition, but they can influence symptoms, residual hearing, listening effort, and day-to-day function. This overview focuses on how lifestyle affects Autosomal recessive nonsyndromic deafness 59 and highlights lifestyle risk factors for Autosomal recessive nonsyndromic deafness 59. Tailoring daily choices can help protect remaining hearing, reduce tinnitus, and improve communication stamina.
Listening to music or media at high volumes can worsen tinnitus and strain any residual hearing. Keeping volume lower and using noise-canceling headphones reduces auditory stress.
Smoking or vaping can reduce inner-ear blood flow, potentially worsening tinnitus and jeopardizing residual hearing. Quitting supports inner-ear health and may improve outcomes with hearing devices.
Excess alcohol can impair central auditory processing and balance, increasing listening effort and fall risk when relying on visual cues. Moderation may ease communication fatigue and steadiness.
Excess salt can aggravate inner-ear fluid dysregulation and make tinnitus or ear fullness more noticeable. Choosing lower-sodium meals may lessen these symptoms.
Risk prevention
For people with Autosomal recessive nonsyndromic deafness 59, you can’t fully prevent the condition because it’s inherited. Prevention works best when combined with regular check-ups. The focus is on planning, early detection, and steps that protect any remaining hearing and support communication from the start. Families may also consider genetic options to reduce the chance of having another child with the same condition.
Meet with a genetics professional to understand how Autosomal recessive nonsyndromic deafness 59 is passed down. They can review your family tree and explain chances for future children.
A blood or saliva test can show if partners carry the same gene change linked to this condition. Knowing carrier status helps guide family planning.
If both partners are carriers, options like IVF with embryo testing or prenatal testing can reduce the chance of an affected child. A counselor can discuss benefits, limits, and timing.
Make sure your baby gets newborn hearing screening right after birth. Early symptoms of Autosomal recessive nonsyndromic deafness 59 can be subtle, so screening helps catch issues quickly.
Transmission
Autosomal recessive nonsyndromic deafness 59 is a genetic form of hearing loss and cannot be caught or passed between people like an infection. It follows an autosomal recessive pattern: a child is affected only when they inherit two nonworking copies of a hearing‑related gene—one from each parent, who usually have typical hearing and are carriers. When both partners are carriers, each pregnancy has a 25% (1 in 4) chance for a child with Autosomal recessive nonsyndromic deafness 59, a 50% (1 in 2) chance for a child who is a carrier like the parents, and a 25% chance for a child who is neither. These odds are the same for boys and girls, and while a new gene change can rarely be involved, the usual genetic transmission of Autosomal recessive nonsyndromic deafness 59 is through two carrier parents—this is how Autosomal recessive nonsyndromic deafness 59 is inherited.
When to test your genes
Consider genetic testing if you have early-onset hearing loss, a family history of childhood deafness, or relatives known to carry DFNB59-related variants. Testing is also helpful before pregnancy or during fertility planning to clarify carrier status and recurrence risk. If already diagnosed, results can guide counseling, device choices, and family screening.
Diagnosis
Diagnosis of Autosomal recessive nonsyndromic deafness 59 often starts when a newborn hearing screen flags changes, or later when speech and hearing milestones don’t progress as expected. From there, specialists look for a pattern that fits a nonsyndromic, likely inherited hearing loss and confirm it with targeted testing. Early and accurate diagnosis can help you plan ahead with confidence. Genetic tests are usually needed to confirm the specific cause and guide family counseling.
Hospitals use quick tests to check how a baby’s ears and hearing nerves respond to sound soon after birth. Abnormal results prompt a repeat screen or a referral to an audiologist for full testing.
Age-appropriate hearing tests map the type and degree of hearing loss in each ear. These may include pure-tone, speech responses, and play-based methods for young children.
This measures how sound signals travel along the hearing nerve to the brainstem. In Autosomal recessive nonsyndromic deafness 59, results may suggest an auditory neuropathy pattern with poor neural synchrony.
A tiny probe checks outer hair cell function in the inner ear. Present emissions with absent or abnormal ABR can support an auditory neuropathy spectrum linked to this condition.
Stages of Autosomal recessive nonsyndromic deafness 59
Autosomal recessive nonsyndromic deafness 59 does not have defined progression stages. This inherited type of hearing loss varies in how early it shows up and how severe it is, and it’s confirmed with hearing checks rather than a standard staging system. Different tests may be suggested to help map the hearing pattern, such as newborn screening, otoacoustic emissions, and the auditory brainstem response. Early symptoms of Autosomal recessive nonsyndromic deafness 59 may include not startling to loud sounds or not turning toward a caregiver’s voice, and genetic testing—often looking at the PJVK gene—can confirm the cause and guide family planning.
Outlook and prognosis
Daily routines often adapt after a diagnosis of Autosomal recessive nonsyndromic deafness 59 (DFNB59/PJVK-related hearing loss), mainly around communication at home, school, and work. Many people ask, “What does this mean for my future?”, and the short answer is that life expectancy is normal because this condition affects hearing without involving other organs. Hearing loss is usually present from early childhood and is typically stable to moderately progressive; some notice difficulties mainly in noisy places, while quiet, one‑to‑one conversations are more manageable. Early symptoms of Autosomal recessive nonsyndromic deafness 59 often show up as delayed response to sounds or frequent “What?” in toddlers, and timely hearing evaluation allows families to get support sooner.
Prognosis refers to how a condition tends to change or stabilize over time. With ARNSHL59, the long-term outlook centers on communication access rather than survival. Most people do well with hearing technology and communication strategies—such as hearing aids, cochlear implants when appropriate, captioning, and sign language—chosen to fit age, preference, and hearing profile. In medical terms, the long-term outlook is often shaped by both genetics and lifestyle, including consistent device use, speech and language therapy, and supportive school or workplace accommodations.
Everyone’s journey looks a little different. Some children make steady gains in speech with early amplification and therapy, while others thrive using sign language or a bilingual approach. There is no known increase in mortality specific to Autosomal recessive nonsyndromic deafness 59, and most health risks relate to missed sounds (for example, alarms or traffic), which can be reduced with safety adaptations. Talk with your doctor about what your personal outlook might look like, including which hearing options and supports are most likely to help now and as needs change.
Long-term effects
Autosomal recessive nonsyndromic deafness 59 tends to affect hearing without involving other body systems. Long-term effects vary widely, from stable moderate hearing differences to profound loss that can gradually progress. Families sometimes ask about early symptoms of autosomal recessive nonsyndromic deafness 59; in many, reduced response to sound appears in infancy or early childhood. Over time, daily routines may shift toward visual cues and structured communication as hearing needs become clearer.
Hearing can range from moderate to profound loss. In some, it stays fairly stable; in others, it slowly worsens over years. Both ears are typically involved.
For some, hearing declines gradually across childhood or adulthood. Others with autosomal recessive nonsyndromic deafness 59 have little change after an early plateau. Doctors may track these changes over years to see patterns.
When hearing loss starts early, speech and language may develop more slowly. With later‑onset loss, clear speech may be present but listening in noise can remain hard. Reading and classroom listening can take extra effort.
Everyday conversations, group discussions, and phone use can be challenging. People with autosomal recessive nonsyndromic deafness 59 often rely more on visual cues and predictable settings. Fatigue from listening effort can build over a day.
How is it to live with Autosomal recessive nonsyndromic deafness 59?
Living with autosomal recessive nonsyndromic deafness 59 often means navigating the world primarily through visual and tactile cues, with communication shaped by sign language, captioning, lip reading, or hearing technology if helpful. Daily life can be rich and connected, but it may require planning—choosing well-lit spaces for conversations, using vibrating or flashing alerts at home, and advocating for access at school, work, and healthcare visits. Family, friends, and coworkers usually become partners in communication, learning signs, using clear visual signals, and respecting preferences to reduce fatigue and misunderstandings. Many find community in Deaf culture and gain confidence as systems and relationships adapt to support full participation.
Treatment and drugs
Autosomal recessive nonsyndromic deafness 59 is treated by improving access to sound and supporting communication rather than changing the gene itself. For many, this means well-fitted hearing aids, remote microphones, and captioning tools; when hearing aids don’t provide enough benefit, cochlear implants may be considered to directly stimulate the hearing nerve. Early diagnosis matters because early symptoms of Autosomal recessive nonsyndromic deafness 59 in infants can affect speech and language development, so families are often offered speech-language therapy and education support alongside devices. Treatment plans often combine several approaches, including auditory training, school accommodations, and family education to build strong communication at home. Genetic counseling can help explain inheritance and future family planning, while regular follow-up lets the care team fine-tune devices and address any new needs over time.
Non-drug treatment
For many, daily life with Autosomal recessive nonsyndromic deafness 59 centers on clearer communication at home, school, and work. Non-drug treatments often lay the foundation for understanding speech, building language, and staying connected. If early symptoms of Autosomal recessive nonsyndromic deafness 59 are noticed in infancy, early referral to hearing services can make a meaningful difference. Plans are tailored, since hearing needs and responses to devices can vary from person to person.
These devices amplify sound to make speech and environmental noises easier to detect. They can be adjusted over time as hearing and listening needs change. Regular checks help keep the settings accurate.
A small device placed by surgery can directly stimulate the hearing nerve when hearing aids are not enough. Outcomes vary in auditory neuropathy, but many gain better access to speech sounds. Careful testing and counseling help set realistic expectations.
FM or digital remote-mic systems send a speaker’s voice straight to hearing devices, cutting background noise. They are useful in classrooms, meetings, and busy cafés. Teachers and coworkers can wear small clip-on mics.
Structured sessions help build clear speech, listening skills, and language. Therapists tailor goals to age and communication style. Home practice between sessions supports steady progress.
Your genes may have an impact on how drugs work for you
Some medications for people with autosomal recessive nonsyndromic deafness 59 may work differently depending on variants in drug‑processing genes, affecting dose needs or side‑effect risk. Genetic testing can guide safer choices, especially for ototoxic drugs that could worsen hearing.
Pharmacological treatments
There are currently no approved medicines that restore hearing in Autosomal recessive nonsyndromic deafness 59. Drugs may be used in specific situations—like a sudden drop in hearing, treating an ear infection, or avoiding medicines that can harm the inner ear. Ask your doctor why a specific drug was recommended for you. Early symptoms of Autosomal recessive nonsyndromic deafness 59 are usually managed with hearing technology and therapy rather than pills.
There are no medications proven to reverse or restore hearing in this condition. Care focuses on hearing devices and communication support while research continues.
If a rapid decline occurs, doctors may try corticosteroids such as oral prednisone or intratympanic dexamethasone. These work best when started quickly, though benefit in genetic hearing loss is uncertain.
Bacterial ear infections are typically treated with antibiotics like amoxicillin to prevent temporary worsening of hearing. This treats the infection, not the genetic cause, and the exact drug depends on age, allergies, and local guidance.
Some medicines can damage hearing, including aminoglycosides like gentamicin and tobramycin, chemotherapy drugs such as cisplatin, and high-dose loop diuretics like furosemide. Let every clinician know about your hearing status so safer alternatives can be considered.
Genetic influences
This form of hearing loss follows an autosomal recessive pattern, meaning a child needs two non-working copies of the same gene—one from each parent—to be affected. Parents are usually healthy carriers who don’t have hearing loss themselves, and in each pregnancy there’s a 25% (1 in 4) chance the child will have autosomal recessive nonsyndromic deafness 59. A “carrier” means you hold the gene change but may not show symptoms. The gene most often involved is called PJVK (pejvakin), which helps the inner ear and the hearing pathway work properly; when both copies are altered, hearing can be reduced from birth or early childhood and may be stable or sometimes change over time. Severity can differ between families and even among siblings, depending on the exact changes in the gene. Genetic testing for autosomal recessive nonsyndromic deafness 59 can confirm the cause and clarify carrier status for parents and adult relatives, and genetic counseling can help you understand the results and options.
Is Autosomal recessive nonsyndromic deafness 59 genetic?
Genetics are central to Autosomal recessive nonsyndromic deafness 59. Variants in both copies of the relevant gene cause the condition, while carriers typically have normal hearing. Family history, consanguinity, and specific ancestral backgrounds can influence risk patterns.
Pharmacogenetics—how genetics influence drug effects
Knowing the exact genetic cause can guide treatment decisions for Autosomal recessive nonsyndromic deafness 59, especially when weighing hearing aids, cochlear implants, or—rarely—an auditory brainstem implant. Because this form of hearing loss often involves how sound signals travel along the hearing nerve, some people do very well with a cochlear implant while others gain only modest benefit; a genetic diagnosis helps set realistic expectations and timing. Medication choices also matter over a lifetime—certain antibiotics (aminoglycosides such as gentamicin) and some chemotherapy drugs (like cisplatin) can damage hearing, and a separate mitochondrial gene change can raise that risk even further. Alongside your medical history and current hearing tests, genetic testing can help doctors plan safer antibiotic options and dosing if you ever need these medicines. There isn’t yet a medicine that reverses this inherited hearing loss, but understanding the gene involved can shape rehabilitation plans and guide careful monitoring whenever ear‑affecting treatments are considered. Treatment is tailored to the individual, factoring in age, degree of hearing loss, and daily communication needs in addition to genetics.
Interactions with other conditions
Other ear or health conditions can change how hearing loss shows up day to day, even when the cause is Autosomal recessive nonsyndromic deafness 59. Recurrent ear infections or fluid behind the eardrum can add a temporary “blocked” hearing layer on top of the permanent loss, making hearing tests and hearing-aid tuning harder to interpret. A condition may “exacerbate” (make worse) symptoms of another—for example, inner-ear infections like meningitis can further injure hearing structures and complicate treatment timing.
Medicines used for other illnesses can also matter: certain antibiotics (aminoglycosides) and some chemotherapy drugs are known to damage hearing, so clinicians usually weigh alternatives and monitor closely. Because Autosomal recessive nonsyndromic deafness 59 can involve an auditory neuropathy pattern, coexisting speech-language delays or neurodevelopmental conditions may make rehabilitation more complex, even though they arise for different reasons. Interactions can look very different from person to person.
How genes can cause diseases
Humans have more than 20,000 genes, each carrying out one or a few specific functions in the body. One gene instructs the body to digest lactose from milk, another tells the body how to build strong bones and another prevents the body's cells from beginning to multiply uncontrollably and developing into cancer. As all of these genes combined are the building instructions for our body, a defect in one of these genes can have severe health consequences.
Through decades of genetic research, we know the genetic code of any healthy/functional human gene. We have also identified that in certain positions on a gene, some individuals may have a different genetic letter from the one you have. We call these hotspots "Genetic Variations" or "Variants" in short. In many cases, studies have been able to show that having the genetic letter "G" in the position makes you healthy, but having the letter "A" in the same position disrupts the gene function and causes a disease. Genopedia allows you to view these variants in genes and summarizes all that we know from scientific research, which genetic letters (Genotype) have good or bad consequences on your health or on your traits.
History
Throughout history, people have described children who did not respond to voices yet were otherwise healthy and active, learning to communicate through signs, gestures, and facial expression long before formal sign languages were widespread. Families sometimes noticed more than one child with hearing loss in the same generation, and grandparents recalled similar stories from earlier decades, hinting at an inherited pattern that skipped parents and appeared in their children.
From early theories to modern research, the story of Autosomal recessive nonsyndromic deafness 59 reflects this path from observation to explanation. Early medical notes simply recorded “congenital deafness” when a baby did not startle to sound or fail a bedside bell test. As newborn hearing screening became routine, more infants were identified in the first days of life. These tools showed that hearing loss could be present at birth or develop in early childhood even when a child looked and grew typically in every other way.
In recent decades, knowledge has built on a long tradition of observation. Advances in genetics helped sort out different causes of inherited hearing loss that look similar on the surface. Researchers found that some families had hearing loss linked to one gene, while others had changes in different genes that affected the inner ear’s delicate sound-sensing hair cells. When scientists recognized a recurring pattern that was present without other medical features and required both parents to carry a silent variant, they grouped it as an autosomal recessive, nonsyndromic form and numbered distinct types as they were discovered.
Autosomal recessive nonsyndromic deafness 59, often shortened to DFNB59 in scientific writing, entered the medical literature as one of these numbered groups once gene studies pinpointed its specific cause. Initially understood only through symptoms—stable or sometimes fluctuating hearing loss in one or both ears—later laboratory tools and imaging helped show that the problem lies in how sound signals are handled in the inner ear and along the hearing pathway, not in the outer ear’s shape or the child’s overall development.
Over time, descriptions became more precise. Clinicians learned that different families with the same diagnosis might have slightly different ages of onset or degrees of hearing loss, while still sharing the core feature of hearing differences without other organ systems being involved. This variability explained why earlier reports were sometimes inconsistent and why some children were missed until school age.
Knowing the condition’s history can help families understand today’s testing and care: what once depended on waiting for speech delays or school hearing checks is now identified early, and genetic testing can confirm the specific type. This shift—from family stories and bedside tests to newborn screening and gene-level answers—has shaped how Autosomal recessive nonsyndromic deafness 59 is recognized and supported.
