The increasing availability of treatments and the importance of early intervention have stimulated newborn screening (NBS) to diagnose LSDs and permit early intervention to prevent irreversible impairment or severe disability.

Enzymatic activity cutoff values were determined from 3500 anonymous newborn DBS.

Ten of 20 had pathogenic mutations: two Pompe, two Gaucher, five Fabry, and one MPS\u2010I. The incidences of Pompe and Gaucher diseases were similar (1\/22,205), with Fabry disease the most frequent (1\/8882) and MPS\u2010I the rarest (1\/44411).
