Scheie syndrome is a mucopolysaccharidosis where the underling defect is deficiency of alpha-L-iduronidase. This is the same deficiency seen in Hurler's syndrome, however in Scheie syndrome it only affects dermatan sulphate, the accumulation of which in tissues is responsible for the clinical manifestations.
- Scheie syndrome patients typically display variable clinical symptoms that can include coarse facial features, corneal clouding, cardiac valve disease, joint stiffness, clawed hands, malaise/fatigue and other somatic features
- onset of these clinical symptoms is usually delayed compared to that in Hurler syndrome patients and the disease progression is less rapi
- in some patients with an attenuated form of the disorder, intelligence can be normal, stature can be relatively normal and the patient can have a normal lifespan
