Hematopoietic stem cell transplantation (HSCT) can be a treatment option for some patients, however the risk-benefit profile is more favourable in younger patients, therefore ensuring an early diagnosis is critical for this to be a viable option. The rationale is that enzyme-producing donor cells repopulate the host tissue and transfer enzyme to nearby enzyme-deficient host cells. Despite early reports to the contrary, The possible benefits of HSCT must be weighed against the overall risk of procedure related morbidity and mortality. The benefits are greater in younger patients before complications have developed, and also transplant related complications are more frequent and severe in older patients.
