Fabry disease is a rare genetic disorder caused by a defective gene (the GLA gene) in the body. In most cases, the defect in the gene causes a deficient quantity of the enzyme alpha-galactosidase A. This enzyme is necessary for the daily breakdown (metabolism) of a lipid (fatty substance) in the body called globotriaosylceramide abbreviated GL-3 or GB-3. When proper metabolism of this lipid and other similar lipids does not occur, GL-3 accumulates in the majority of cells throughout the body. The resulting progressive lipid accumulation leads to cell damage. The cell damage causes a wide range of mild to severe symptoms including potentially life-threatening consequences such as kidney failure, heart attacks and strokes often at a relatively early age.
