Histopathological evidence of Fabry disease in a female patient with left ventricular noncompaction
Fabry disease is a rare X-linked lysosomal storage disorder caused by mutations in the alpha-galactosidase gene. The most frequent cardiac presentation of Fabry disease is cardiomyopathy characterized by left ventricular (LV) hypertrophy, usually concentric.Heart disease in affected females tends to...
