Mucopolysaccharidosis-plus syndrome is a new type of mucopolysaccharidosis (MPS) that is not caused by deficiency of lysosomal enzyme. Patients show typical manifestations of MPS, and extremely high levels of plasma heparan sulphate. Additionally, most patients develop heart, kidney, and hematopoietic disorders. It has been suggested that mutations in the VPS33A gene might be responsible for this disease. VPS33A plays a role in the vesicular transport system.
