Hello Marian! I thank you for a greeting. To me of 28 years, at me son Ivan of 6 years DMD. Has learnt about the diagnosis half a year back. In our country becomes nothing for children with our diagnosis, it is not spent any researches, there is no even a base given in which children with this diagnosis on all country would be considered how many. In this connection I am compelled to address for foreign sites. I am sorry for my bad English.
