The long-term-outlook for people with<unk>  depends on the subtype and the severity of the condition in each person. The severe infantile forms of<unk>  are associated with shortened life expectancy, with most untreated children not surviving past their first decade. Bone marrow transplantation seems to have cured some infants with early-onset disease. However, the long-term prognosis after transplantation is unknown. For those with onset in childhood or adolescence, the effect of the condition depends on the specific symptoms (including how fragile the bones are and how much pain is present). Life expectancy in the adult-onset forms is normal.
