Prognosis Prognosis depends on the severity of the disease and on the quality of care, which can allow patients to survive beyond the age of 50. The documents contained in this web site are presented for information purposes only. [orpha.net]

The prognosis (long-term outlook) depends upon the particular type of MPS. There are a number of different types of MPS that are designated somewhat confusingly by number (and letter), by syndrome name, and by precising what enzyme is lacking. [medicinenet.com]
