Assessment of a symptomatic Duchenne muscular dystrophy carrier 20 years after myoblast transplantation from her asymptomatic identical twin sister
2013
Because it is due to a mutation on the X-chromosome, Duchenne muscular dystrophy rarely affects women, unless there is an unequal lyonisation of the X-chromosome containing the normal dystrophin gene. We report here the unique situation of a symptomatic Duchenne muscular dystrophy woman who was transplanted with myoblasts received from her asymptomatic monozygotic twin sister 20 years ago. Specific dynamometry was performed to possibly detect a long-term effect of this cell therapy. Long-term safety of myoblast transplantation was established by this exceptional case. However, long-term efficacy could not be definitively asserted for this patient, in spite of several clues suggesting beneficial effects. 2013 Elsevier B.V. All rights reserved.
