LaboratoryCathepsin A [Enzymatic activity/mass] in Leukocytes
Definition
Cathepsin A enzyme activity in leukocytes is measured as part of a diagnostic work-up for galactosialidosis. Patients with galactosialidosis will have decreased activity of the protective protein as well as decreased neuraminidase and β-galactosidase activity in leukocytes (and/or fibroblasts). Sequencing of the CTSA gene is performed for detection of disease-causing mutations.
