What are the symptoms of Branchiooculofacial syndrome ?
What are the signs and symptoms of Branchiooculofacial syndrome? The characteristic signs and symptoms of BOFS include skin defects, eye abnormalities, and distinctive facial features. These features vary among affected individuals. The skin defects include proliferation of blood vessels (hemangiomatous) in the lower neck or upper chest; lumps in the area of the neck or collarbone (branchial cleft sinuses); and linear skin lesions behind the ears. Eye abnormalities can include microphthalmia, coloboma, and strabismus. The distinctive facial features can include widely spaced eyes; the presence of a pseudocleft of the upper lip resembling a poorly repaired cleft lip; a malformed nose with a broad bridge and flattened tip; blockage of the tear ducts (lacrimal duct obstruction); and malformed ears. Often, affected individuals may have burn-like lesions behind the ears. Other features can include delayed growth, thymic and kidney abnormalities, dental abnormalities, and hearing loss. Intellect is usually normal.  The Human Phenotype Ontology provides the following list of signs and symptoms for Branchiooculofacial 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.

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. + GARD + Branchiooculofacial syndrome
