[Microsatellite analysis of Duchenne muscular dystrophy].

Duchenne muscular dystrophy is X-linked recessive neuromuscular disorders caused by mutations in the dystrophin gene. Prenatal diagnosis and carrier detection are usually performed using diallelic RFLP-markers which are not always informative. Now 30 of microsatellite marker have reported, these microsatellite polymorphism can easily be amplified using PCR technique. If mutations are known to localize in this region of the dystrophin gene or if routine RFLP-analysis is uninformative, the analysis of microsatellite markers is the preferable technique in prenatal diagnosis and carrier detection.
