I have myopathy, which is a lessor form of the MD that my son had, he had Duchenne type, other relatives had Limb Girdle, and Becker's. When you are a carrier as I was, sometimes at a later age, (I am 69) this does show up in the mother but in a lessor form. Anyway, am pretty familiar with MD, my son lived to the age of 37, dx'd at age 6, wasn't supposed to live that long, but he did, and good for him!
