Prediction of neuropathology in mucopolysaccharidosis I patients

Abstract

Mucopolysaccharidosis I is a lysosomal storage disorder caused by a deficiency of the lysosomal hydrolase alpha-l-iduronidase, which is required for the degradation of heparan sulphate and dermatan sulphate. Given the wide spectrum of disease severity in mucopolysaccharidosis I patients, one of the challenges for managing the disorder is to accurately predict clinical phenotype. Enzyme replacement therapy by intravenous infusion is unlikely to make a significant impact on central nervous system pathology and patients displaying this clinical manifestation may respond better to bone marrow transplantation. In order to predict whether mucopolysaccharidosis I patients are going to develop centr..
