A bilateral, whorl-like corneal pattern of cream-colored lines in a person with Fabry disease Angiokeratoma, a common skin manifestation in Fabry disease Symptoms are typically first experienced in early childhood and can be very difficult to understand; the rarity of Fabry disease to many clinicians sometimes leads to misdiagnoses. Manifestations of the disease usually increase in number and severity as an individual ages. Pain Full-body or localized pain to the extremities (known as acroparesthesia) or gastrointestinal (GI) tract is common in patients with Fabry disease. This pain can increase over time. This acroparesthesia is believed to be related to the damage of peripheral nerve fibers that transmit pain. GI-tract pain is likely caused by accumulation of lipids in the small vasculature of the GI tract, which obstructs blood flow and causes pain. Kidney Kidney complications are common and serious effects of the disease; chronic kidney disease and kidney failure may worsen throughout life. The presence of protein in the urine (which causes foamy urine) is often the first sign of kidney involvement. End-stage kidney failure in those with Fabry disease typically occurs in the third decade of life, and is a common cause of death due to the disease. Heart Fabry disease can affect the heart in several ways. The accumulation of sphingolipids within heart muscle cells causes abnormal thickening of the heart muscle or hypertrophy. This hypertrophy can cause the heart muscle to become abnormally stiff and unable to relax, leading to a restrictive cardiomyopathy causing shortness of breath. Fabry disease can also affect the way in which the heart conducts electrical impulses, leading to both abnormally slow heart rhythms such as complete heart block, and abnormally rapid heart rhythms such as ventricular tachycardia. These abnormal heart rhythms can cause blackouts, palpitations, or even sudden cardiac death. Sphingolipids can also build up within the heart valves, thickening the valves and affecting the way they open and close. If severe, this can cause the valves to leak (regurgitation) or to restrict the forward flow of blood (stenosis). The aortic and mitral valves are more commonly affected than the valves on the right side of the heart. Skin Angiokeratomas (tiny, painless papules that can appear on any region of the body, but are predominant on the thighs, around the navel, buttocks, lower abdomen, and groin) are common. Anhidrosis (lack of sweating) is a common symptom, and less commonly hyperhidrosis (excessive sweating). Additionally, patients can exhibit Raynaud's disease-like symptoms with neuropathy (in particular, burning extremity pain). Ocular involvement may be present showing cornea verticillata (also known as vortex keratopathy), i.e. clouding of the corneas. Keratopathy may be the presenting feature in asymptomatic patients, and must be differentiated from other causes of vortex keratopathy (e.g. drug deposition in the cornea). This clouding does not affect vision. Other ocular findings can include conjunctival and retinal vascular abnormalities and anterior/posterior spoke-like cataract. Visual reduction from these manifestations is uncommon. Other manifestations Fatigue, neuropathy (in particular, burning extremity pain, red hands and feet on and off), cerebrovascular effects leading to an increased risk of stroke - early strokes, mostly vertebrobasilar system tinnitus (ringing in the ears), vertigo, nausea, inability to gain weight, chemical imbalances, and diarrhea are other common symptoms.
