Overview
- Fabry disease (also known as alpha-galactosidase A deficiency, ceramide trihexosidase deficiency, angiokeratoma corporis diffusum, Anderson Fabry disease) is an X-linked recessive inherited lysosomal storage disorder.
- It occurs as a result of the body's inability to make an enzyme alpha-galactosidase A. This enzyme encoded by the GLA gene located on the long arm of the X chromosome (q21-22) is in-turn responsible for breaking down a type of fat called globotriaosylceramide (Gb3 or GL-3) into building blocks that are used by the cells of the body.
- The abnormal accumulation of this fat typically in three main organ systems namely the brain, heart and kidney is responsible for the varied manifestations associated with the disease
- Glycosphingolipid storage initiates a cascade of events that begins with the dysfunction of basic metabolic processes on the cellular level followed by progression to cell death, inflammatory events, and progressive major organ dysfunction.[2]
- Prenatal and neonatal studies of the histopathology of Fabry disease have confirmed that pathogenic GL3 accumulations occur in the maternal region of the placenta, fetal tissues, and the fetal placenta regions of affected males. In male fetuses affected these accumulations have been found in renal, myenteric plexus, and liver cells.This prenatal storage suggests that the process of Fabry disease may lead to early childhood symptoms[3][4]
- Fabry disease is a rare condition that can affect people regardless of their ethnic background. The prevalence for Fabry's disease is estimated to range from 0.27 to 1.69 per 100,000 in men, and 0.33 to 3.47 per 100,000 in women.
Historical Perspective
- Anderson - Fabry disease was first described at the end of the 19th century by two dermatologists, Johannes Fabry in Germany and William Anderson in England.
- In 1989 the origin of one of its many clinical names, "angiokeratoma corporis diffusum" was first identified by fabry as he described a clinical case of a13-year-old patient affected by nodular purpura and subsequent albuminuria. In that same year Anderson described the clinical case of a systemic disorder affecting a patient aged 39 with angiokeratomas, proteinuria, finger deformities, varicose veins and lymphedema.
- The first ten years of the 20th century identified other similar cases.
- In the year 1912, Madden illustrated the clinical case of a young Egyptian patient with diffuse angiokeratomas followed in 1915 by Fabry who reproposed this condition as "Angiokeratoma corporis naeviforme".
- In 1947 Pompen speculated the origin of Anderson - Fabry disease as rather “familial” after the clinical case of two brothers dying of a similar disease was identified.
- Anderson - Fabry Disease is a multi-systemic disorder caused by the build-up inside lysosomes of globotriaosylceramide or Gb3, the accumulated lipid material discovered in 1963 by Sweeley e Klionsky.In
- In 1964 the clinical features of the main two phenotypes of the disease, the classical form and the atypical variants were described.
- In the ‘70s the enzyme involved in the metabolism of Gb3 was found to be α-galactosidase A, whose functional deficit causes the disease. The enzyme is encoded by the GLA gene - described in 1974 - located in the long arm of the X chromosome (q21-22).
- In the mid-1990s the many efforts to replace the lacking enzyme were successful and further led to the enzymatic replacement therapy for Anderson - Fabry disease. [1]
- The limited information available on Fabry disease in early childhood has made application of the guidelines of the pediatric Fabry Registry and American College of Medical Genetics and Genomics difficult in the population of children diagnosed prenatally or during infancy
Classification
- Classic form- Most commonly seen in males. It is a severe form of the disease.
- Atypical variant. Milder, late-onset forms of the disorder are probably more common than the classic, severe form.
- Based upon complications
- Cardiac variant
- Renal variant
- Non-neuropathic form
- Neuropathic form
- Infantile form
- Juvenile form
