La MPS II, anche conosciuta come sindrome di Hunter, è causata dalla mutazione del gene iduronato-2-solfatasi (IDS), che determina una carente scissione di glicosaminoglicani (GAG), eparan e dermatan solfato, causa di un progressivo accumulo intracellulare di GAG con conseguenti patologie multisistemiche progressive.1,2
