Jones syndrome

Prevalence
Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Inheritance

Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease.

Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype.

Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.

Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Summary

Jones syndrome is a very rare condition characterized by gingival fibromatosis (enlargement and overgrowth of the gums) and progressive, sensorineural hearing loss.[1] The onset of gingival fibromatosis usually occurs with the eruption of the permanent teeth. Excessive growth of the gums may cause displacement of teeth, over-retention of primary teeth, and increased spacing.[2] Jones syndrome is inherited in an autosomal dominant manner, but the underlying genetic cause is not yet known.[1] Only a few families with Jones syndrome have been reported.

Symptoms

Jones syndrome is primarily characterized by gingival fibromatosis (slowly progressive enlargement of the gums) and progressive, sensorineural hearing loss. Enlargement of the gingival tissue usually begins at the time the permanent teeth are erupting, although it may occur before.[3] Excessive growth of the gums may cause displacement of teeth, over-retention of primary teeth, increased spacing, speech problems, and painful chewing.[2] Absence of teeth (oligodontia) and extra (supernumerary) teeth have also been reported in people with Jones syndrome.[4] Hearing loss has been reported to begin in the second or third decade of life and is bilateral (in both ears).[4]

Overlapping of symptoms with other syndromes associated with hereditary gingival fibromatosis (HGF) has been reported, including Zimmermann-Laband syndrome and gingival fibromatosis-hypertrichosis syndrome (HGF with excessive hair growth). It has been proposed that the overlapping features reported may represent a spectrum of a single disorder, rather than separate syndromes.[3]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Cause

The exact, underlying genetic cause of Jones syndrome is not yet known.[2]

Treatment

Due to the rarity of Jones syndrome, there are no treatment guidelines available in the medical literature. However, there is information about how the features associated with Jones syndrome might be treated.

Treatment for gingival fibromatosis varies depending on the severity. Maintaining good oral hygiene is very important. Surgery to remove the enlarged gum tissue in the mouth (gingivectomy) may be needed for functional and/or cosmetic reasons. Enlargement may recur to various extents, and repeated surgeries may be needed to reshape the gums. It has been recommended that whenever possible, this treatment should be performed after the complete eruption of permanent teeth.[2]

The goal of treatment for sensorineural hearing loss is to improve hearing. People with sensorineural hearing loss may use hearing aids; telephone amplifiers and other assistive devices; sign language (for those with severe hearing loss); and/or speech reading (such as lip reading and using visual cues to aid communication). A cochlear implant may be recommended for some people with severe hearing loss.[5]

Organizations

Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer.
