Hi Ina,
 
Thanks for your answer 
 
So this is how I understod it : for many years to come, xrays will still be necessary and sometime in a far away future, it will be possible to give only HD-results "good" or "bad" by DNA, but not more specific than that... and 
maybe in an even further away future it will be possible to give exact(A,B,C,D,E) HD-results from DNA ...for both GSD and CSW !
 
Please correct me if I am wrong ?
 
Greetings Rolf
