    ### Response:
    What causes muscle eye brain disease? Muscle eye brain disease is caused by mutations in the POMGNT1 gene. This gene provides instructions for making a protein that is involved in adding sugar molecules to a protein called alpha dystroglycan. Alpha dystroglycan is important for stabilizing the muscle cell during contraction and relaxation.
