Definition

Sanfilippo syndrome is one of the hereditary mucopolysaccharide storage diseases, which are characterized by the absence of one of several enzymes. Normally, these enzymes help rid the body of a substance found outside of our cells, called a mucopolysaccharide.

In Sanfilippo syndrome, large amounts of a mucopolysaccharide called heparan sulfate is excreted in the urine.

Overview, Causes, & Risk Factors

Sanfilippo syndrome is transmitted as an autosomal recessive trait. It is possibly the most common of the mucopolysaccharide storage diseases. In Sanfilippo syndrome, onset is relatively late, rather than during the first year of life.

As with most of the mucopolysaccharide storage diseases, affected individuals have coarse facial features, decreased mental development that progresses to severe mental retardation, stiff joints, gait disturbances, speech disturbances, and behavioral problems.

Unlike Hurler syndrome, in people with Sanfilippo syndrome, the cornea is clear, the condition is not as unrelenting, and survival times are longer, often into the 20s or later.
