Fabry disease

Fabry disease is a rare inherited disorder of glycosphingolipid (fat) metabolism resulting from the absent or markedly deficient activity of the lysosomal enzyme, α-galactosidase A (α-Gal A). This enzymatic deficiency is caused by alterations (mutations) in the α-galactosidase A (GLA) gene that instructs cells to make the α-galactosidase A (α-Gal A) enzyme. Lysosomes function as the primary digestive tract of cells. Females typically have a more variable course and may be asymptomatic or as severely affected as their male relatives.
