The symptoms described in the question are classic signs of Duchenne muscular dystrophy, which is the most common and severe type of muscular dystrophy in children. It typically affects boys and is caused by a mutation in the DMD gene, resulting in a progressive weakness of the muscles. Other types of muscular dystrophies, such as limb-girdle muscular dystrophy, facioscapulohumeral muscular dystrophy, and congenital muscular dystrophy, may also cause muscle weakness, but they have different patterns of inheritance and symptom onset.
