Introduction
Fabry disease (FD) is a rare X-linked lysosomal storage disorder caused by pathogenic variants in the GLA gene, resulting in impaired activity of α-galactosidase A.(1) This enzymatic deficiency leads to progressive accumulation of globotriaosylceramide and related metabolites in vascular endothelial cells and multiple organs, including the heart, kidneys, and nervous system.(1, 2) The prevalence of Fabry disease in the general population has traditionally been estimated at approximately 1 in 40,000–140,000 individuals.(1, 3) Although newborn screening programs, particularly in Taiwan, have provided well-defined estimates of Fabry disease prevalence and have revealed a substantially higher frequency of late-onset variants, population-based genomic data remain limited in other Asian populations. (1, 4) This study aimed to determine the prevalence of Fabry disease–causing variants in genome sequencing data from a community-based cohort in the Tohoku Medical Megabank, Japan.
