α-Galactosidase activities in plasma and leukocytes from three known patients with Fabry diseasea

PatientPlasma (nmol/h per ml)Leukocytes (nmol/h per mg protein)
  • a Activities were assayed in the absence and presence of 100 mM GalNAc inhibitor (thus measuring “Total” and “A,” respectively). Reference range for total activity in leucocytes 42.1 to 112.9 nmol/h per mg protein; reference range for total activity in plasma 3.0 to 8.1 nmol/h per ml.
