Anyone have Branchiootorenal syndrome (BOR or BOS syndrome)?

It involves abnormalities of the ear and/or neck and it may or may not involve kidney malformations.

The severity varies, so some people have no real indication of the syndrome, whereas others may have serious kidney complications.

I ask because the mutated genes involved are genes that have also been linked to breast cancer. But I can't find any studies on overlap between BOR/BOS and breast cancer, nor any studies on how BOR/BOS affects (or doesn't) breast cancer incidence, survival etc.
