What kind of doctor treats Pendred Syndrome?
A primary care doctor often coordinates care, usually with an ear, nose, and throat doctor and an audiologist. An endocrinologist may manage thyroid issues, and a genetic counselor can help families. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is Pendred syndrome?
Pendred syndrome is a rare genetic condition passed down through families. It causes hearing loss present at birth or starting early in childhood, and it can cause the thyroid gland to become enlarged or underactive.
Pendred syndrome is an inherited condition affecting the inner ear and the thyroid gland. Most people have hearing loss from birth or early childhood, and many have balance problems. Some develop a goiter, and the thyroid may become underactive.
Symptoms
Hearing loss is usually the first sign. It is often sensorineural and can worsen over time. Balance problems are common. A goiter can swell the neck, and an underactive thyroid can cause tiredness, weight gain, and feeling cold.
Causes and who gets it
Pendred syndrome is caused by changes in a gene called SLC26A4. A child must receive a changed copy from both parents; parents carrying only one copy usually have no symptoms. It is rare and affects both boys and girls.
How doctors diagnose it
Doctors often start with a hearing test called an audiogram. MRI or CT scans can show an enlarged vestibular aqueduct, a fluid channel wider than normal in many people with this condition. Blood tests check the thyroid, and genetic testing can confirm the diagnosis.
Treatment
There is no cure, but treatments can help. Hearing loss is often treated with hearing aids, and some people benefit from cochlear implants. Children may get speech therapy. An underactive thyroid is treated with hormone pills, and balance problems may improve with physical therapy.
When to see a doctor
Anyone with hearing loss in early childhood, unexplained dizziness, or neck swelling should see a doctor. Children with a family history of hearing loss should be checked early.
How a direct primary care or concierge doctor fits in
A direct primary care or concierge doctor can manage everyday parts of this condition, including ordering hearing and thyroid tests and prescribing hormone pills, and can refer patients to specialists when needed. Longer visits and smaller patient panels can make coordinating care easier.
Common questions
What are the features of Pendred syndrome?
Pendred syndrome involves hearing loss plus other features, most often balance problems and thyroid changes. Not everyone with the syndrome has every feature. The thyroid problems may not appear until later in life.
Will my children have Pendred syndrome if I am a carrier?
Carrying one changed copy of the gene usually causes no symptoms. A child would need to receive a changed copy from both parents to have the syndrome. A genetic counselor can explain the chances for a specific family.
Does the hearing loss in Pendred syndrome get worse?
In some people, the hearing loss does get worse gradually, while in others it stays stable. Head injuries or sudden pressure changes can sometimes cause sudden drops in hearing. Regular hearing tests help track any changes.
Is the goiter in Pendred syndrome dangerous?
A goiter in Pendred syndrome is a swelling of the thyroid gland, and it is not usually cancer. Doctors can check the thyroid with an exam, blood tests, and sometimes imaging or a biopsy to be sure. Most people are managed with monitoring or hormone pills.
