May indicate Becker muscular dystrophy in quadriceps-limited weakness; leaves open need for larger confirmatory studies.
Case Report (n=4)
Quadriceps myopathy can be a forme fruste of Becker muscular dystrophy, characterized by dystrophin abnormalities.
Sunohara et al. (1990) conducted a case report in Quadriceps myopathy (n=4). Dystrophin examination in muscle biopsy specimens was evaluated on Abnormalities of dystrophin. Examination of muscle biopsy specimens from 4 male patients with quadriceps myopathy revealed clear abnormalities of dystrophin, consistent with forme fruste Becker muscular dystrophy.
