Fabry disease: an ultrastructural comparative study of skin in hemizygous and heterozygous patients.

Fabry disease is a rare X-linked lysosomal storage disorder due to alpha galactosidase A deficiency, better known after the advent of a promising treatment, a periodical enzyme replacement. As other hereditary X-linked disorders, females have historically been considered non-affected carriers, although they are, actually, clinically and pathologically affected to a variable degree. Some women are asymptomatic, but the majority present milder forms of the disease and later onset.
