Fabry Disease

Males with Fabry disease have attacks of abdominal pain and arthralgia. Vascular skin lesions (angiokeratoma) are frequent, and vascular lesions may also occur elsewhere, including ocular fundi and kidney. Whorl-like corneal dystrophy is not uncommon. Neurological symptoms include autonomic dysfunction, orthostatic hypotension, and acroparasthesia. Angina, exercise intolerance and EKG changes occur, often with normal coronary arteries, heart size and hemodynamics, although left ventricular wall and septal hypertrophy are not infrequent. Respiratory complications include chronic airflow obstruction. Ultimately, renal failure may cause death. Females who harbor a mutation in the GLA gene may have manifestations of the disorder, including renal, cardiac and cerebrovascular involvement, angiokeratomas and corneal epitheliopathy. Fabry disease is due to inactivating mutations in the X-linked GLA gene resulting in deficiency of the enzyme alpha-galactosidase A.
