My son is 14 months old and we just got his diagnosis confirmed last week. The doctor is saying a cautious Beckers diagnosis/borderline Duchenne? Has anyone had that or a similar deletion? How are your son's doing? His CK is 26,970 currently. With being so new to everything I am trying to learn as much as possible. My son also has these "body tremors" I call them and also what the neurologist refers to as Stereotyipies. His hands and feet almost constantly "flap" or "wring" almost like he is screwing in a light bulb. Do any of your boys have anything like that?
