The relationship of vascular glycolipid storage to clinical manifestations of Fabry disease: a cross-sectional study of a large cohort of clinically affected heterozygous women (original) (raw)

Medicine, 2005

Abstract

Fabry disease is a rare X-linked lysosomal storage disorder caused by deficient activity of alpha-galactosidase A (alpha-Gal A) resulting in the storage of glycosphingolipids, especially globotriaosylceramide (Gb3), in cells throughout the body, causing life-threatening renal, cardiac, and cerebrovascular complications in hemizygous males and some heterozygous females. Disease manifestations in heterozygotes are being recognized increasingly, but quantitative prospective data on their extent and severity are limited. Prospective clinical and laboratory assessments were performed in a 7-day study of 61 women with signs and symptoms of Fabry disease. Analyses included medical history and physical, neurologic, cardiac, and ophthalmologic assessments; laboratory assessments; renal function tests; magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) of the head; and Fabry-related blood and urine tests, including Gb3 levels in blood and urine, skin biopsies, and DNA g...
