Although its a in frame deletion the signs are of DMD at an age of 2.5 years. these may be due that exon 5 is more critical over others. could anyone has specific information on this. My sons cousine also has the same deletion he is 11, need mostly support to walk. we are giving only vitamin E and calcium supplements to my son.
My sons have deletion of 3-12 that is inframe but still duchenne. y older one has had signs since the age of 18 months and the younger one is showing signs, he is 2,5 years old.
