Analysis of the Nervous System in Patients With Fabry's Disease
Fabry's disease a genetic disorder (X-linked recessive) due to the absence of the enzyme ceramidetrihexosidase. The disease is characterized by abnormal collections of glycolipids in cells (histiocytes) within blood vessel walls, tumors on the thighs, buttocks, and genitalia, decreased sweating, tingling sensations in the extremities, and cataracts. Patients with Fabry 's disease die from complications of the kidney, heart, or brain.
The purpose of this study is to measure levels of a protein marker (PGP 9.5) in the skin, blood, and fluid surrounding the brain and spinal cord (CSF) in patients with Fabry's disease. In addition the study will attempt to determine if levels of the protein are directly related to the severity of disease in the nervous system.
PGP 9.5 protein levels will be measured in normal volunteers and patients with other diseases of the nervous system then compared to the levels recorded in patients with Fabry's disease.
This research study is designed to improve the understanding of Fabry's disease. Patients participating in it will not directly benefit from it. However, knowledge gained as a result of this study may contribute to the development of effective therapies for Fabry's disease.
