 The purpose of this study is to compile a registry of patients with Fabry disease, an inherited metabolic disorder. In this disease, an enzyme called a-galactosidase A, which normally breaks down a lipid fatty substance called globotriaosylceramide Gb3, is missing or does not function properly. As a result, Gb3 accumulates, causing problems with the kidneys, heart, nerves, and blood vessels. It is not known exactly how lipid accumulation causes these problems, but in another lipid storage disease called Gaucher disease the illness can be reversed if the accumulated lipid is removed by repeated intravenous into a vein infusions of the deficient enzyme.
