I have been trying to find out if it is possible to only 'carry' the defective gene for myotonic dystrophy and not actually have the condition? Reason I ask, is that my father had MD, being diagnosed age 30. I am aware that symptoms become more severe from generation to generation, due to the expansion of the defective gene. I am one of 3 children, and both myself and my brother have had the genetic test for MD, and do not have the condition, however, my other brother has never been tested. He is now age 33, and I suspect if he did have MD the symptoms would have appeared by now. However, he has a son, and I worry if there is a possibility MD could still be passed on?

This is not the full answer I think you are looking for:
When the faulty gene is passed on by a man it doesn't always expand, and if it does expand it generally doesn't expand by large numbers. The only sure way to find out is by having the genetic test.
I know some people with DM1 and the only thing they have was cataracts.
Hope this helps a little
