BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2012008148 DESCRIPTION Hurler syndrome is a rare lysosomal storage disorder with a prevalence of 1 in 100 000. It is caused by a defective IDUA gene which codes for α-L iduronidase and has an autosomal recessive inheritance. Enzyme deficiency results in accumulation of der...

BACKGROUND Cardiovascular disease, a progressive manifestation of α-L-iduronidase deficiency or mucopolysaccharidosis type I, continues in patients both untreated and treated with hematopoietic stem cell transplantation or intravenous enzyme replacement. Few studies have examined the effects of α-L-iduronidase deficiency and subsequent glycosaminoglycan storage upon arterial gene expression to ...

Mucopolysaccharidosis I-Hurler (MPS I-H) is the most severe form of a metabolic genetic disease caused by mutations of IDUA gene encoding the lysosomal α-L-iduronidase enzyme. MPS I-H is a rare, life-threatening disease, evolving in multisystem morbidity including progressive neurological disease, upper airway obstruction, skeletal deformity and cardiomyopathy. Allogeneic hematopoietic stem cel...
