    ### Instruction:
    What are the genetic changes related to Fukuyama congenital muscular dystrophy ?
    ### Response:
    Fukuyama congenital muscular dystrophy is caused by mutations in the FKTN gene. This gene provides instructions for making a protein called fukutin. Although the exact function of fukutin is unclear, researchers predict that it may chemically modify a protein called alpha ()-dystroglycan.
