    What are the treatments for Metachromatic Leukodystrophy ?
    ### Response:
    There is no cure for MLD. Bone marrow transplantation may delay progression of the disease in some infantile-onset cases. Other treatment is symptomatic and supportive. Considerable progress has been made with regard to gene therapy in an animal model of MLD and in clinical trials.
