I,ve written before about the results of DNA testing that was done on my family, because in 1989 my son was diagnosed with saltlosing CAH. The results being 95% accurate, showed that my husband and I did not have any mutations detected on our alleles, and that our son had only one detected mutation. The genetic counselor tried to explain to me, without much convincing, how my son could have gotten CAH without the genetic make-up from his parents. Meaning that it, from what I have read and searched out, that it takes two mutations to get this condition. Can someone else explain to me if what I just said to be accurate, how my son has CAH. Everything I read says that this is genetic. Should I be concerned or am I just missing something? I would like to know of anybody that has also obtained their DNA tests, if they were even done, and I believe that they definitely should be. I know not many parents that I've seen on the message board have this kind of concern but this has been nagging at me for quite a while and I would appreciate any feedback. Thank You to all who respond
