What are the symptoms of Jones syndrome ?
What are the signs and symptoms of Jones syndrome? 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. Excessive growth of the gums may cause displacement of teeth, over-retention of primary teeth, increased spacing, speech problems, and painful chewing. Absence of teeth (oligodontia) and extra (supernumerary) teeth have also been reported in people with Jones syndrome. Hearing loss has been reported to begin in the second or third decade of life and is bilateral (in both ears). 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. The Human Phenotype Ontology provides the following list of signs and symptoms for Jones syndrome. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Delayed eruption of teeth 90% Gingival overgrowth 90% Sensorineural hearing impairment 90% Autosomal dominant inheritance - Gingival fibromatosis - Progressive sensorineural hearing impairment - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
