Metachromatic Leukodystrophy (MLD) and gene therapy: a game-changing treatment backed by NEJM—Timing Is Everything

A recent study published in the New England Journal of Medicine found that gene therapy can significantly reduce the risk of severe motor and cognitive impairment in children with metachromatic leukodystrophy (MLD). The therapy, administered early, preserves motor function and cognitive abilities in most patients.

Gene therapy a possibility for metachromatic leukodystrophy?

Researchers have successfully treated mice with gene therapy, reversing neurological damage and deficits caused by the genetic defect that leads to metachromatic leukodystrophy. The treatment involves using hematopoietic stem progenitor cells genetically modified to express high levels of ARSA protein.
