β¦ Synopsis
Duchenne muscular dystrophy (DMD) is an X-linked degenerative disorder of muscle, caused by gross rearrangements by the dystrophin gene in two-thirds of cases. The remaining one-third of patients may carry more subtle mutations that are difficult to detect because of the large size and complexity of this gene (Roberts et al., 1994).

Three unrelated patients with HC were studied. The diagnosis of coproporphyria was based on the observation of typical clinical manifestations, increased excretions of Γ-aminolevulinic acid and porphobilinogen in urine and coproporphyrin III in both feces and urine, and 50% decreased COX activity in
Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) are X-linked neuromuscular disorders associated with alterations in the dystrophin gene. Analysis of 45 DMD/BMD patients has identified 18 patients with no deletion in the dystrophin gene. Heteroduplex analysis (HD), single strand
