Metachromatic Leukodystrophy – Enzyme Analysis

Disease name Metachromatic leukodystrophy
Enzyme Name Arylsulfatase A
Clinical info Metachromatic leukodystrophy is an autosomal recessive condition caused by a deficiency of arylsulfatase A, an enzyme crucial to the breakdown of sulfatides in the body. Metachromatic leukodystrophy should be considered in any individual with progressive neurological dysfunction and MRI evidence of a leukodystrophy. This condition can present in late-infantile, juvenile and adult forms.
Indications Patients with a suspected diagnosis of metachromatic leukodystrophy through clinical symptoms and MRI findings. Prenatal diagnosis and carrier testing via enzyme analysis are not available.
Methodology Measurement of enzyme activity
Specimen Requirements Arylsulfatase A can be measured from leukocytes or fibroblasts. For leukocytes, please send 5-10 ml of whole blood in a green top (sodium heparin) tube.
Transport Leukocytes must arrive at the laboratory within 24 hours of blood draw. Please contact the laboratory before transporting tissue for an enzyme assay. Fresh tissue for culture should be sent by courier or 24-hour delivery
Turnaround time 14 days
Cell culture can take 1-4 weeks and may lengthen turnaround time.
