The National MPS Society and its members raise money to provide student fellowships and fund research projects. We participate in and host technical conferences that allow researchers to collaborate and discuss their findings. We collaborate with other lysosomal storage disease (LSD) patient support groups and family research foundations to fund research.
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.
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.
