Bradley has an exon 2 duplication. I'm wondering what this will mean for his progression. I'm thankful to say he is still walking at age 11. Sometimes I believe his gait is getting worse and other times it seems he is about the same. He seldom uses his wheel chair....like maybe twice per year. But I'm glad we have it on hand in case he really needs it. It is a manual so we will have to get a power wheel chair if he starts uses it often. I wonder if his particular duplication causes a slower progression. The doctor says although DMD is confirmed, he progresses as if he had BMD. I can't wait to hear Dr. Wong's opinion whatever that may be.
