title: Detection of deletions within the dystrophin gene in Polish families affected with Duchenne/Becker muscular dystrophy.
abstract: DNA analysis was performed in 190 cases of Duchenne and Becker muscular dystrophies (DMD/BMD), including 150 cases with DMD and 40 cases with BMD, using Southern blotting and PCR multiplex techniques with application of 25 pairs of primers. Deletions in the overall material were found in 109 cases: 81 (54%) in patients with DMD and 28 (70%) in patients with BMD. All the deletions in DMD were out of frame with the exception of two cases, whereas in BMD all the deletions but two were in frame. Junction fragments were detected in 12 cases of DMD. In five cases duplications were found: four in patients with DMD and one in a patient with BMD.
