Categories:

Congenital and Genetic Diseases; Ear, Nose, and Throat Diseases; Nervous System Diseases

Summary Summary

The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.

Orpha Number: 3219

Definition

Fountain syndrome is an extremely rare multi-systemic genetic disorder characterized by intellectual disability, deafness, skeletal abnormalities and coarse facial features.

Epidemiology

The syndrome is exceedingly rare and has been reported in only a few patients to date. Male and female patients have been described.

Clinical description

The main clinical features of Fountain syndrome include moderate to severe intellectual deficit, congenital sensorineural hearing impairment, and broad, stubby hands and feet. A coarse face with full lips and cheeks is also found. These signs are reported to become more prominent with age. Additional reported signs are early-onset, generalized seizures, short stature, large head circumference, and remarkable behavior (friendly demeanor).

Etiology

The etiology of Fountain syndrome has not been elucidated.

Genetic counseling

The pattern of inheritance appears to be autosomal recessive.

Symptoms Symptoms

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.
