Multiple sulfatase deficiency is a lysosomal storage disorder that mainly affects the brain, skin, and skeleton. The signs and symptoms of this condition vary widely, prompting researchers to divide it into three types: neonatal, late-infantile, and juvenile. The neonatal type is the most severe form, with symptoms developing soon after birth. The late-infantile type is the most common form and usually presents as progressive loss of mental abilities and movement after a period of normal development. The juvenile type is rare, with a slow regression of psychomotor development in mid to late childhood. Life expectancy is shortened in all types. Multiple sulfatase deficiency is caused by mutations in the SUMF1 gene. It is inherited in an autosomal recessive pattern. There is no cure for multiple sulfatase deficiency. Treatment includes physical therapy and supportive services.
