As we are just breeders and not the God , of course problems could appear. The question is always that how could we handle the problems.
DM is exist . But it is quite complex problem, as that kind of physical ruination could be caused many many other things , especial old age. There are many illnes with almost the same symphtoms.
We still do not know too many things about DM , still are many open questions.
So I think we have to make DM test...but we have to handle the result in "right place". These test will have spell some years later , when more % of the population will be checked and we could see the problematic lines and the inheritance of the bad gene (which is real cause problem).
