Something which had always crossed my mind was, if a GS/BS sufferer had a kidney transplant (not that this is normally an option, as transplants only tend to be available if your kidney is actually failing, which in the case of GS/BS it isn't- it's just not working properly) would the GS/BS "reprogram" it so that it also wasted salt, potassium, magnesium etc.?
I asked this question to Ben Walsh at the national GS/BS Patient Day in London earlier this month and he told me that no, the kidney woukd not be affect by GS and would work perfectly, thus, in essence, curing the GS.
So, if you'd ever also wondered about it, there's the answer.
As an aside, I was also told of a case where a patient had had kidney failure, had received a kidney transplant and, as a result, had been "given" Gitelmans as the donor had been an undiagnosed sufferer.
So it seems it really is the kidney that's the problem and not the body as a whole influencing any particular organ(s).
