title: Dystrophin test in differential diagnosis of childhood muscular dystrophies.
abstract: Two cases of childhood muscular dystrophy are described. One of them had clinical features suggestive of Emery-Dreifuss muscular dystrophy and the other with some features of Prader-Willi syndrome, besides proximal muscle weakness. Muscle biopsy from both cases revealed a clear abnormality of dystrophin, and were diagnosed as having Duchenne muscular dystrophy (DMD) by immunofluorescence examination; that is, absent dystrophin at the membrane of the muscle fibers. The clinical spectrum of DMD-related myopathies and the importance of dystrophin testing in childhood muscular dystrophies is discussed.
