Congenital Disorder

Multiple Sulfatase Deficiency Disease

An inherited metabolic disorder characterized by the intralysosomal accumulation of sulfur-containing lipids (sulfatides) and MUCOPOLYSACCHARIDES. Excess levels of both substrates are present in urine. This is a disorder of multiple sulfatase (arylsulfatases A, B, and C) deficiency which is caused by the mutation of sulfatase-modifying factor-1. Neurological deterioration is rapid.
