Fabry disease in a female patient due to a de novo point mutation at position 691 of exon 5.
Fabry disease is an X-linked lysosomal disorder caused by deficiency of the lysosomal enzyme alpha-galactosidase A. We report on a 32-year-old female patient with an 8-year history of vascular lesions on the hips and periumbilical region and a presumed Fabry disease without positive family history. Ophthalmologic evaluation revealed whorl-like corneal opacities. Echocardiography revealed myxomatous degeneration and prolapse of the mitral valve. DNA analysis of the alpha-galactosidase A gene confirmed the diagnosis of Fabry disease, showing a de novo point mutation at position 691 of exon 5. The patient is now obtaining intravenous enzyme replacement therapy with agalsidase alfa and remains without drug-related reactions.
