Late gadolinium enhancement shows increased signal of the midwall at the inferolateral wall of the base of the left ventricle, usually in the non-hypertrophic ventricle. T1-weighted imaging can show low T1 signal due to sphingolipid storage in the heart even without ventricular hypertrophy in 40% of the those affected by the disease. Thus, MRI is a useful way of diagnosing the disease early. T2 signal is increased in inflammation and oedema. Treatment
The treatments available for Fabry disease can be divided into therapies that aim to correct the underlying problem of decreased activity of the alpha galactosidase A enzyme and thereby reduce the risk of organ damage, and therapies to improve symptoms and life expectancy once organ damage has already occurred. Therapies targeting enzyme activity
Enzyme replacement therapy is designed to provide the enzyme the patient is missing as a result of a genetic malfunction. This treatment is not a cure, but can partially prevent disease progression, and potentially reverse some symptoms. As of March 2022, two medical drugs based on enzyme replacement therapy are available for Fabry disease:
Agalsidase alfa, sold under the brand name Replagal by the company Takeda (since its acquisition of the company Shire), is a recombinant form of alpha-galactosidase A It received approval in the EU in 2001. FDA approval was applied for the United States. However, Shire withdrew their application for approval in the United States in 2012, citing that the agency will require additional clinical trials before approval. As of March 2022, Replagal has not received FDA approval.
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 Raynauds 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. Causes
Fabry disease is caused by a DNA sequence (gene) that is not functioning as it should. A person who inherits this gene does not have enough of a functioning enzyme known as alpha-galactosidase A. The lack of alpha-galactosidase  leads to Fabry disease. A deficiency of alpha galactosidase A (a-GAL A, encoded by GLA) due to mutation causes a glycolipid known as globotriaosylceramide (abbreviated as Gb3, GL-3, or ceramide trihexoside) to accumulate within the blood vessels, other tissues, and organs.
