CaseEnzymeAssay: The α-L-iduronidase enzyme activities in leucocytes from all patients in the study was measured using the artificial substrate 4-methylumbelliferyl α-L iduronide (Sigma). Values ranged from 0 to 2.47 nmol/h/mg protein (reference range: 28–92 nmol/h/mg protein) and did not correlate to the clinical phenotype.

α-L-iduronidase activity in COS-7 cells transiently transfected with wild-type or mutagenised cDNAs. α-L-iduronidase activity: 4.5 nmol/h/mg cell protein; values are the means of two experiments.
