Branchio-oto-renal syndrome is a rare autosomal dominant disorder of the first and second embryonic branchial arches and the urinary tract. It is characterized in its full expression by branchial fistulas or cysts, preauricular pits, outer, middle and inner ear defects, hearing loss, lachrymal duct stenosis, facial paralysis and mental retardation. Renal anomalies may range from mild hypoplasia to complete absence. Our report demonstrates the patient with classical BOR syndrome and severe renal insufficiency since infancy up to end stage renal failure at 18 years of age caused by bilateral renal hypoplasia. Although no definitive histological diagnosis was made, the clinical findings in our patients, like mild proteinuria, normal blood pressure, polyuria, polydypsia, hyperchloremic acidosis and typical course of renal failure support the diagnosis of oligomeganephronia in this case.

Branchio-oto-renal (BOR) syndrome is an autosomal dominant, clinically heterogeneous disorder characterized by branchial arch anomalies, hearing impairment, and renal malformations. We report the case of a 10-year-old boy with BOR syndrome who presented with hyperkalemic hyperchloremic metabolic acidosis due to hyporeninemic hypoaldosteronism. The child also had mental retardation and spastic diplegia which have hitherto not been described in BOR syndrome.
