Objective: Duchenne and Becker muscular dystrophy (DMD/BMD) is an X-linked lethal recessive disease caused by mutations in the dystrophy gene. There is no efficient treatment for this serious and disabling disease. We established a combination method to detect carriers and perform prenatal diagnosis. Methods: In our study, from 1994 to 2005, using a different combination of 5 methods, including SRY gene amplification, multiplex PCR, multiplex Fluorescence PCR capillary electrophoresis, multiplex ligation-dependent probe amplification (MLPA) and linkage analysis of short tandem repeats (STR), 36 prenatal diagnosis were performed for pregnancies at risk of having a DMD/BMD baby through amniocentesis. Results: Fourteen out of 21 male fetuses were found to be affected and respective pregnancies were terminated. A combined diagnostic rate of 83
