| Remarks |
Clinically affected; inherited balanced translocation (maternal); diagnosed with DMD at age 12; onset of symptoms at age 6; toe gait; flexion deformities of hips, knees and Achilles tendon; marked hypertrophy of the calves; positive Gower's sign; lumbar lordosis; markedly elevated CPK; muscle biopsy consistent with DMD; mother (GM09982) is also affected; donor subject shows a duplication of exons 2-4 of the dystrophin gene by multiplex ligation probe amplification (MLPA) analysis |
