I asked my son's doctor that a while ago and was told that it doesn't matter what exon is missing. Some are more common than others, but I guess there is no information to suggest that one is worse or better than another. My son is missing exon 58. I haven't seen anyone on this website that had that exon missing. I've even pressed the whole cpk level issue as well because my son's was around 4,600 when diagnosed and most others are around 10,000 - 30,000 as diagnosis. Of course, I thought/hoped for sure that that would mean he would have a milder case, but they just don't know. Unfortunately, there are so many unknown's with this disease.
hello I read in treat nmd that when the first exons are missing or the last the exon skiping treatment cannot be done
