Hurler Syndrome (Mucopolysaccharidosis Type I) Overview

Hurler syndrome, the most severe form of mucopolysaccharidosis type I, is a rare autosomal recessive lysosomal storage disorder caused by a deficiency of alpha-L-iduronidase encoded by the IDUA gene. This results in progressive intralysosomal accumulation of dermatan sulfate and heparan sulfate across multiple organ systems. Patients present in infancy with coarse facial features, hepatosplenomegaly, skeletal dysostosis multiplex, corneal clouding, and progressive neurological deterioration with cognitive regression, causing severe disability or early mortality if untreated. Diagnosis integrates elevated urinary glycosaminoglycans, deficient leukocyte enzyme activity, and confirmatory IDUA sequencing. Standard management historically relied on allogeneic hematopoietic stem cell transplantation before two years of age to prevent progressive cognitive decline, using intravenous laronidase as a somatic bridge. However, the treatment paradigm has been fundamentally transformed by autologous stem cell gene therapies like OTL-203, which provide targeted metabolic correction without the graft-versus-host risks of allogeneic transplant. Furthermore, historical intrathecal delivery investigations have been superseded by blood-brain barrier-penetrating biologics. Modern neuro-enzyme replacement therapies utilize insulin or transferrin receptor-mediated transcytosis antibody fusions, allowing systemic weekly intravenous infusions to successfully cross the blood-brain barrier and clear heparan sulfate from the central nervous system. Coordinated multidisciplinary care remains mandatory to preserve long-term survival.
