Hurler SyndromeMPS I
📋Overview
Mucopolysaccharidosis Type I (MPS I) is a rare inherited lysosomal storage disorder caused by deficiency of the enzyme alpha-L-iduronidase. This leads to accumulation of glycosaminoglycans (GAGs) in various tissues, causing progressive multi-systemic symptoms. MPS I encompasses a spectrum of severity, historically classified into Hurler syndrome (severe), Hurler-Scheie syndrome (intermediate), and Scheie syndrome (mild), but now recognized as a continuous range rather than distinct subtypes.
