Fabry Disease (FD; OMIM 301500) is a rare lysosomal storage disorder caused by mutations in the GLA‐gene, which codes for the enzyme α‐galactosidase A (enzyme commission no. 3.2.1.22).1 Reduced or absent activity of this enzyme results in the accumulation of glycosphingolipids such as globotriaosylceramide (Gb3) in various cells types throughout the body. The gene discussed is GLA; the disease is Fabry disease.
