My brother has BMD and I was tested at the time he was (about 20 years ago) and I was found to be a carrier. My son was tested by blood test (since we had the dna info from my testing) and was found to be affected. My son is only 2 and I am starting to see some symptoms in him, and I'm worried that maybe he could have DMD. We have his yearly MDA clinic appointment in a week and I'm getting more and more nervous. Has anyone heard of both types being in the same family? I feel like I know a lot about these diseases since my brother is pretty severly affected (he had to have a heart transplant at 16), but I can't find the answer to this question! Thank you :)
