Fabry's disease: long-term study of a family.
Fabry's disease is the second most prevalent lysosomal storage disorder after Gaucher's disease. It occurs as the result of a deficit in the alpha-galactosidase A enzyme. The gene coding for it is located on the long arm of the X chromosome (Xq22.1). This deficit causes the gradual accumulation of a glycosphingolipid. The main substance accumulated is globotriaosylceramide (Gb3). This accumulation leads to pain and angiokeratomas, and to cardiac, cerebral, and vascular involvement as the disease progresses. The treatment of Fabry's disease has so far only been symptomatic; however, new advances have now made it possible to prescribe alpha-galactosidase replacement therapy, which not only improves symptoms, but also enhances these patients' quality of life and lowers mortality. In this paper we review the status of Fabry's disease and we report the follow-up of a family with Fabry's disease, with some members receiving replacement therapy with alpha-galactosidase A and demonstrating good progress.
