Branchio-oto-renal (BOR) syndrome and Branchiootic (BO) syndrome show overlapping phenotypes of bilateral conductive hearing loss, branchial defects, and facial abnormalities. Individuals with BOR syndrome have renal anomalies as well. Mutations in the EYA1 or its transcription cofactor SIX1 and SIX5 are responsible for the diseases.
