BRCA gene mutation

Hi has anyone been diagnosed with BC because of a BRAC gene mutation. I have BRAC1 mutation with no family history.

Would be good to hear from others around Australia, possibly in Sydney or NSW.

It seems that having triple neg is rare enough, but unfortunately having a gene mutation is even rarer. I thought that having one genetic problem was enough (adrenal insufficiency) now I find out I have BRAC too.

I must have bad genes that have somehow skipped the rest of my family!
