I don’t see a purpose in it. You already know you have to be the carrier since your son has it. Men don’t give it to their sons. Knowing if you have the premutation or the full mutation isn’t going to change your life in any way. I wouldn’t waste my time with it.
I am a fragile x carrier with two children, a boy who doesn’t have it, and a girl who is a carrier. I found out because my dad has FXTAS and my sisters and I were advised to get tested and have our children tested. I didn’t know at the time that I was automatically a carrier as a male automatically passes the x on to daughters and never sons. My daughter’s learning disability was always something that we dealt with while she was in school, she was tested for ADD but not fragile x as that was something they considered more with boys. She had many of the ADD issues without the hyperactivity. The biggest being executive function problems. I know in many ways she has been relieved to find that it was not a matter of her “not trying hard enough” as the teachers always told her. Too bad we didn’t find out she was affected by fragile x till after she was finished with school. They say girls dont have so many problems with it, but I know she really struggled. Any way, the test is pretty expensive and as the person who wrote the previous comment said, you already know you are a carrier because that is how your son got the gene.
I wasn’t tested until approx. 7 years after Kyle’s diagnosis; this is also when Chelsey was tested. We were going to participate in a Stanford U. study, but Chelsey’s full mutation status prevented us from doing so (I had always assumed that she was either a carrier or not affected at all). We’ve never had Matt tested (he’s 14)—obviously, he has the gene; knowing his number of repeats isn’t important.
I guess my instinct was right, there is no real point. The medical professionals are the ones who bring it up most often. I guess I’ll just stick with “not yet” as my response.
