    ### Instruction:
    What are the genetic changes related to Emery-Dreifuss muscular dystrophy ?
    ### Response:
    Mutations in the EMD and LMNA genes cause Emery-Dreifuss muscular dystrophy.  The EMD and LMNA genes provide instructions for making proteins that are components of the nuclear envelope, which surrounds the nucleus in cells. The nuclear envelope regulates the movement of molecules into and out of the nucleus, and researchers believe it may play a role in regulating the activity of certain genes.
