Not to confuse the issue.. Just thinking of someone who has posted before that both both a spouse and ex were carriers, but of different mutations...
So isn't there always the possibility that because you had different fathers, that you and your brother had the potential to carry a different gene -- if he's a carrier. And then what about your brother's wife/partner -- isn't there a chance that if she's a carrier that she too might have a completely different gene.
The only reason I mention this is my MIL drives me nuts because whenever we talk about testing, she tells me that she wants to get tested because then when it comes back clear she can tell her family that they're "safe" because the gene obviously came from my FIL's side of the family. And I try to explain til I'm blue in the face that they could BOTH be carriers and it could just be the luck of the draw...
