Jones Syndrome: Causes, Symptoms, and Treatment

What kind of doctor treats Jones Syndrome?

A primary care doctor is usually the first stop and can examine the gums, order hearing tests, and coordinate care. A dentist or an oral surgeon may treat the gum overgrowth. An ear, nose, and throat doctor, also called an ENT, manages the hearing loss. An audiologist performs detailed hearing exams.

What it is

Jones syndrome is a very rare condition that affects two parts of the body. People with it have overgrowths of the gums, which doctors call gingival fibromatosis. This means firm, non-cancerous lumps of tissue on the gums. They also develop hearing loss that slowly gets worse over time, called sensorineural hearing loss.

So few people have it that doctors have learned about the condition mostly from a small number of families described in medical journals.

Symptoms

The two main signs are gum overgrowth and hearing loss. The gum overgrowth often appears in childhood. The gums may look large, firm, and lumpy, and the extra tissue can cover part of the teeth.

The hearing loss usually starts later and gets worse slowly.

Causes and who gets it

Jones syndrome appears to run in families and is thought to be passed down in an autosomal dominant pattern: a child only needs to get the changed gene from one parent. The exact gene involved has not been clearly identified.

How doctors diagnose it

A doctor will start with a medical history and a physical exam, looking at the gums and asking about hearing changes and family history.

Hearing is checked with a test called an audiogram, which measures how well a person hears different sounds and pitches.

Treatment

There is no treatment that removes the cause of Jones syndrome, so care focuses on managing each symptom. Gum overgrowth is often treated with surgery that trims away the extra tissue, called a gingivectomy. The tissue can grow back, so some people need more than one surgery.

Hearing loss is managed with hearing aids. Regular hearing tests help track any change.

When to see a doctor

See a doctor if the gums look swollen, firm, or lumpy, or if they are growing over the teeth, or for any hearing loss or ringing in the ears. Children with a parent who has Jones syndrome should be checked.

Common questions

Is Jones syndrome dangerous?

It is not known to be life threatening. The main problems are the gum overgrowth and the hearing loss, both of which can be managed with care. Each person's experience is different.

Can the gum overgrowth come back after surgery?

Yes, it can. The extra gum tissue sometimes grows back over months or years, so some people need repeat procedures. Good dental hygiene may help slow this.

Will hearing aids fix the hearing loss completely?

Hearing aids usually make sounds easier to hear, but they do not restore hearing to normal. How much they help depends on how severe the hearing loss is. An audiologist can adjust them over time as hearing changes.

Should my children be tested if I have Jones syndrome?

Because the condition appears to run in families, a child of a person with Jones syndrome has some chance of having it too. A doctor or a genetic counselor, a specialist who explains inherited conditions, can talk through testing options.
