Arylsulphatase A, Blood


Arylsulphatase A is an enzyme involved in the normal catabolism of cerebroside sulphatide. The arylsulphatase A gene, located on chromosome 22, has a few common mutations causing enzyme deficiency which result in juvenile and adult onset Metachromatic Leucodystrophy (MLD), a neurodegenerative lysosomal storage disease, in addition to psuedoarylsulphatase deficiency. MLD, in its severe form, presents in the first 2 years of life with spastic paraparesis and developmental delay whereas in the adult form it is associated with dementia and behavioural problems.
