Abstract

Metachromatic leukodystrophy (MLD) is a lysosomal storage disease caused by deficiency of the lysosomal enzyme arylsulfatase A. Deficiency of this enzyme results in intralysosomal storage of sphingolipid cerebroside 3-sulfates (sulfatides), which are abundant in myelin and neurons. A pathological hallmark of MLD is demyelination and neurodegeneration, causing various and ultimately lethal neurological symptoms. This review discusses the potential therapeutic application of hematopoietic stem cell gene therapy and intracerebral gene transfer (brain gene therapy) in patients with MLD.
