Fabry Disease Overview

Fabry disease is a rare X-linked lysosomal storage disorder caused by mutations in the GLA gene, leading to deficient activity of the -galactosidase A enzyme. This results in the accumulation of globotriaosylceramide (Gb3) in various organs, particularly the kidneys, heart, and nervous system. Symptoms range from pain, heat intolerance, angiokeratomas, and gastrointestinal issues to serious complications such as progressive kidney failure, cardiomyopathy, arrhythmias, and stroke. The disease affects both males and females, though severity varies, with late-onset forms being more common and often diagnosed in adulthood. Early detection through newborn screening and genetic testing is improving diagnosis rates. Current treatments include enzyme replacement therapies (ERTs) such as FABRAZYME and REPLAGAL, and chaperone therapy like GALAFOLD, which aim to reduce substrate buildup and slow disease progression. Emerging therapies, including substrate reduction therapies and gene therapies, hold promise for more durable and targeted disease management.

Fabry Disease Epidemiology

In 2024, the United States recorded approximately 9,200 diagnosed prevalent cases of Fabry disease, accounting for nearly 52% of the total 7MM population. The EU4 and the UK together contributed around 38%, while Japan represented roughly 10% of the diagnosed population. Within Europe, Germany reported the highest number of diagnosed cases (~2,170), whereas Spain reported the lowest.

In the US, the burden was driven largely by the late-onset phenotype (~5,860 cases), compared with about 3,300 cases of the classic phenotype. By age distribution, prevalence peaked in the 10-19 year group (~1,920 cases), followed by 20-29 years (~1,780), 30-39 years (~1,700), 40-49 years (~1,430), and approximately 1,180 cases each in the and 50+ years groups.

These trends highlight the strong predominance of late-onset disease and the significant concentration of cases in younger age groups, emphasizing the critical need for early detection and timely intervention in Fabry disease management.
