What Is Fabry disease?
Fabry disease is an inherited genetic Lysosomal disorder that results from the buildup of a particular type of fat, called globotriaosylceramide, in the body's cells. Beginning in childhood, this buildup causes signs and symptoms that affect many parts of the body. Characteristic features of Fabry disease include; episodes of pain, particularly in the hands and feet (acroparesthesias); clusters of small, dark red spots on the skin called angiokeratomas; a decreased ability to sweat (hypohidrosis); cloudiness of the front part of the eye (corneal opacity); problems with the gastrointestinal system; ringing in the ears (tinnitus); and hearing loss. Fabry disease also involves potentially life-threatening complications such as progressive kidney damage, heart attack, and stroke. Some affected individuals have milder forms of the disorder that appear later in life and affect only the heart or kidneys.

What is OMIM?
Online Mendelian Inheritance in Man® or OMIM is a comprehensive, authoritative compendium of human genes and genetic phenotypes that is freely available and updated daily. The full-text, referenced overviews in OMIM contain information on all known mendelian disorders and over 15,000 genes. OMIM focuses on the relationship between phenotype and genotype. It is updated daily, and the entries contain copious links to other genetics resources. OMIM is authored and edited at the McKusick-Nathans Institute of Genetic Medicine, Johns Hopkins University School of Medicine.
The OMIM for Fabry disease is # 301500

The Incidence of Fabry disease
Fabry disease occurs amongst all races and ethnicities. The “classical” subtype of Fabry disease, characterized by early onset, aects approximately 1:40,000 men. However, several literature reports suggest that Fabry disease may be significantly under diagnosed and the prevalence of the disease may in fact be much higher, particularly in the midler variants of the disease (Clarke 2007). Based on a Newborn Screen Study, Spada et al. (2006) estimated that the incidence of Fabry disease may be 1 in 3,100 to 4,600 individuals depending upon the demographics of the population under study.
Why is the disease called 'Fabry disease'?
Fabry disease was first identified in 1898 by two dermatologists working independently, Dr William Anderson in England and Dr Johannes Fabry in Germany. They separately published papers in which they described patients with skin lesions, known as angiokeratomas, which are now recognised as a common sign of Fabry disease. The disease has a number of names, including angiokeratoma corporis diffusum, alpha-galactosidase A deficiency, and was for many years known as Anderson-Fabry disease, but is now usually referred to simply as Fabry disease.
Misdiagnosis of Fabry Disease
Misdiagnosis is common in Fabry disease due to its rarity. Fabry disease has been mistaken for;
- Ménière’s disease
- Crohn’s disease
- Multiple sclerosis
- Rheumatic fever
- Raynaud syndrome
- Irritable bowel syndrome
