Fabry disease - Vascular manifestations.
Fabry disease (FD) is an X-linked disorder of glycosphingolipid metabolism caused by the deficient activity of alpha-galactosidase A which results in the accumulation of neutral glycosphingolipids in various tissues leading particularly to vasculopathy, cardiomyopathy, neuropathy, and chronic kidney disease. It results in substantial morbidity and premature death in affected patients. Although there are some signs and symptoms suggestive of FD including painful crisis, angiokeratomas, and corneal changes, the majority of FD complications are non-specific (left ventricular hypertrophy, conduction abnormalities, vascular spasms, proteinuria, renal insufficiency), which is why FD still remains largely underdiagnosed. The mechanism by which accumulating glycosphingolipids cause multiorgan disorder is not yet completely understood as it cannot be explained by pure substrate storage. Besides standard therapy of different medical problems in FD patients, specific enzyme replacement therapy has been introduced in the last few years.
