This test evaluates the activity of alpha-galactosidase A enzyme that has been associated with Fabry disease.

This test may be appropriate for individuals with a clinical suspicion of Fabry disease and/or individuals with a family history of Fabry disease.

Fabry disease is a lysosomal storage disorder with a wide spectrum of symptoms ranging from mild cases in females, to severe cases in classically affected hemizygous males. Symptoms may include abdominal and joint pain, vascular lesions and corneal abnormalities. Neurological symptoms include autonomic dysfunction and burning sensation or numbness in the extremities. Fabry disease affects an estimated 1 in 40,000 to 1 in 60,000 males. The prevalence is unknown in females.
