|---|---|
| Other names | MPS I-S |
| Patient with Scheie syndrome | |
| Symptoms | Symptoms are variable, but may include: mild learning disabilities, psychiatric issues, visual problems, skeletal deformities, carpal tunnel syndrome, aortic valve disease, and/or sleep apnea |
| Usual onset | Symptoms may appear by age 5; diagnosis is usually made after age 10 |
| Causes | Deficiency of the alpha-L iduronidase enzyme |
| Differential diagnosis | Other forms of MPS I; Hunter syndrome; other mucopolysaccharidoses |
| Treatment | Enzyme replacement therapy with iduronidase; surgery may be necessary |

Scheie syndrome is a disease caused by a deficiency in the enzyme iduronidase, leading to the buildup of glycosaminoglycans (GAGs) in the body. It is the most mild subtype of mucopolysaccharidosis type I; the most severe subtype of this disease is called Hurler Syndrome.
Scheie syndrome is characterized by corneal clouding, facial dysmorphism, and normal lifespan.[2][3] People with this condition may have aortic regurgitation.[4]
