Gaucher disease is an autosomal recessively inherited storage disorder caused by deficiency of the lysosomal hydrolase, acid β-glucosidase. The disease manifestations seen in Gaucher patients are highly heterogeneous as is the responsiveness to therapy. The elucidation of the precise factors responsible for this heterogeneity has been challenging as the development of clinically relevant animal models of Gaucher disease has been problematic.

Monitoring of therapeutic response in mucopolysaccharidosis (MPS) patients is problematic as most biomarkers are specific for either disease complications or specific organ system involvement. Recent studies have indicated that serum heparin-cofactor II-thrombin complex (HCII-T) may serve as an important biomarker in the group of MPSs where dermatan sulphate is stored. This complex forms when blood coagulates in the presence of glycosaminoglycans (GAGs) where the ultimate amount of HCII-T that forms reflects the concentration of circulating GAGs.

The mucopolysaccharidoses are a group of lysosomal storage disorders caused by defects in the degradation of glycosaminoglycans. Each disorder is characterized by progressive multi-system disease with considerable clinical heterogeneity. The clinical heterogeneity of these disorders is thought to be related to the degree of the metabolic block in glycosaminoglycan degradation which in turn is related to the underlying mutation at the respective locus.
