Branchio-oto-renal syndome (BOR)


Branchio-oto-renal syndrome (BOR) is an autosomal dominant disorder, often exhibiting variable phenotype within families that includes hearing loss, branchial fistulae, ear pits and kidney malformation. Analysis is by sequencing of EYA1, followed by MLPA to detect deletions and duplications. Mutations in SIX1 and SIX5 are rare, but associated with the same phenotype
