Biomarkers and Cardiac Imaging Diagnostic Assay for Monitoring Patients With Fabry Disease

Fabry disease (FD) is a rare X-linked lysosomal storage disorder caused by deficient activity of the enzyme α-Gal A resulting from mutations affecting the GLA gene. It is characterized by severe multi-systemic involvement that leads to major organ failure and premature death in affected men and in some women. The α-Gal A deficiency results in progressive accumulation of un-degraded glycosphingolipids, predominantly globotriaosylceramide (Gb3), within cell lysosomes throughout the body.1 In patients at the fourth to fifth decade, left ventricular hypertrophy occur usually, and myocardial infarction and heart failure develops disease progress. Life-threatening renal, cardiac, and cerebrovascular diseases are added in later decades.2,3 Fabry disease is treatable with enzyme replacement therapy (ERT).
