Which disease does my child have?

MPS I (Hurler-Scheie) is a continuum of severity based upon the symptoms, ranging from severe to attenuated. There is a great deal of variability of symptoms among individuals with MPS I, often making the specific designation difficult. Generally, severe MPS I will present within the first year of life while less severe (attenuated) forms present during childhood. Although individuals with attenuated MPS I have normal intelligence, they may have a variety of symptoms that can range from mild to severe.

How common are these diseases?

Severe MPS I occurs in approximately 1 in 100,000 newborns. Attenuated MPS I is less common and occurs in about 1 in 500,000 newborns.
