The branchio‐oto‐renal (BOR) syndrome: Report of bilateral renal agenesis in three sibs

Abstract

We report a man who had the branchio‐oto‐renal (BOR) syndrome with crossed renal ectopia. His three children were born with bilateral renal agenesis and the so‐called Potter syndrome. This case illustrates the potential severity of the renal anomalies in the BOR syndrome and the inadequacy of oligohydramnios and maternal serum alpha‐fetoprotein as screening methods for renal agenesis. This case also implies strongly the necessity for meticulous search for renal anomalies in individuals with the BOR syndrome and proper counseling regarding the possiblity of lethal bilateral renal agenesis.
