Mucopolysaccharidosis Type I Overview
Mucopolysaccharidosis Type I (MPS I) is a rare genetic disorder caused by a deficiency of the enzyme alpha-L-iduronidase, which is needed to break down certain complex sugars called glycosaminoglycans (GAGs). The accumulation of GAGs in the body leads to progressive damage in multiple organs and tissues, including the heart, liver, spleen, bones, and nervous system. Symptoms can range from skeletal abnormalities, developmental delays, and organ enlargement to respiratory and cardiovascular issues, with severity varying based on the form of the disease (Hurler, Hurler-Scheie, or Scheie).
