Duchenne/Becker muscular dystrophy (DMD/BMD) is a progressive muscle-wasting disease. The dystrophin gene responsible for the disease is the largest human gene ever cloned and is prone to gross gene deletion in two "hot spot" regions. Using nine pairs of oligonucleotide primers deduced from the two regions, we have screened 23 unrelated Chinese DMD/BMD patients by multiplex polymerase chain reaction. Nine (39%) patients were noted to have gene deletion, one in the 5' terminus and eight in the distal half of the gene. The incidence is similar to that reported in other large series mainly on Caucasian patients. The "hot-spot" regions also seem to be present in Chinese patients. Multiplex gene amplification for deletion analysis is useful in the diagnosis of patients with neuromuscular diseases and is an important aid in the prenatal diagnosis and genetic counseling of at-risk families.
