Metachromatic leukodystrophy
Synonyms: Arylsulfatase A deficiency | MLD
A rare lysosomal disease characterized by accumulation of sulfatides in the central and peripheral nervous system due to deficiency of the enzyme arylsulfatase A leading to demyelination. Three clinical subtypes can be distinguished based on the age of onset: late infantile juvenile and adult. Lead symptoms are deterioration in motor or cognitive function or behavioral problems depending on the subtype all eventually culminating in a decerebrated state and death after a highly variable disease course and duration. Mode of inheritance is autosomal recessive.
