Enzyme activity results for LSD NBGS negative, carriers and positive samples. Enzyme activity of A GALC (cutoff value = 0.43 µM/h), B GAA (cutoff value = 1.22 µM/h), CASM (cutoff value = 0.39 µM/h), D IDUA (cutoff value = 0.44 µM/h), and E GLA (cutoff value = 2.33 µM/h). *P < 0.05. ***P < 0.001. The dotted line near the bottom of each figure refers to the cutoff value
