What are the signs ans symptoms of branchiootorenal syndrome?

Signs and symptoms of branchiootorenal syndrome can vary greatly from person to person and even between people within the same family.[1] Hearing loss is the most common symptom and is shared by approximately 90% of people with this syndrome. Hearing loss may be conductive, sensorineural, or a combination of both.[2][3] Other common signs and symptoms include branchial cleft cysts, branchial fistulae, outer, middle, and inner ear malformations, and kidney malformations.[4][2][5][1] Specifically mutations in the EYA1 or SIX1 genes can be associated with kidney malformations.[5]
