Brief Summary

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.

Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • All patients with Fabry's disease will be considered as potential candidates for this study.

You may not qualify if:

  • All candidates must be serologically nonreactive for human immunodeficiency (AIDS) virus. HIV positive patients will be excluded because of the effects of the latter illness on the nervous system.
  • Patients with Fabry's disease will be excluded from participation if they have additional illnesses such as cancer, diabetes or vasculitis that could potentially involve the nervous system.
  • The general health and well being of each candidate must be sufficient to allow for a modest amount of blood drawing, collection of appropriate laboratory specimens and performance of necessary roentgenograpic and magnetic resonance (MR) imaging studies. In addition, each candidate must be able to return to the National Institutes of Health (NIH) annually for monitoring of clinical and laboratory parameters.
