What is Fabry Disease and Fabry Disease Market?
Fabry disease (FD) is a devastating, progressive, inherited a condition caused by lysosomal dysfunction linked to chromosome X and mutations
in the GLA gene located in chromosome Xq22.1 which encodes the
alpha-galactosidase A (AGA) enzyme.
It is a multi-systemic and life-threatening condition which
is one of the most common lysosomal storage diseases after the Gaucher Disease.
It is characterized by specific neurological, cutaneous, renal, cardiovascular,
cochleovestibular and cerebrovascular manifestations. The symptoms include chronic
pain, usually a burning or tingling sensation in the hands and feet.
The pain sometimes briefly becomes more intense, requiring
medication to bring it down to manageable levels. The pain can go away in
adulthood, clusters of small, dark red spots in various locations on the skin,
opaque corneas, resulting in cloudy-looking eyes and problems with eyesight,
ringing in the ears, and hearing loss, a variety of gastrointestinal problems,
decreased ability to sweat, and others.
The primary disease process starts in infancy, or even as
early as in the fetal stage of development. In FD, lysosomal storage and
cellular dysfunction are believed to trigger a cascade of events including
cellular death, compromised energy metabolism, small vessel injury, K(Ca)
channel dysfunction in endothelial cells, oxidative stress, impaired autophagosome
maturation, tissue ischemia and, importantly, development of irreversible
cardiac and renal tissue fibrosis.
Fabry Disease Classifications
Fabry Disease is classified as the Type 1 classic and Type 2
later-onset on the basis of phenotype of the disease. Both sub-types result in
renal failure, and/or cardiac disease, and early death. Type 2 later-onset
Fabry Disease is more frequent as compared to Type 1 classic Fabry Disease.
Fabry disease, at first can resemble normal growing pains or
arthritis, but other symptoms start to appear with time. Fabry is confirmed
with a test measuring levels of alpha-galactosidase. If low levels of the
enzyme are found, genetic testing for the mutated GLA gene is done. Symptoms of
the disorders like Schindler disease, Gaucher disease, Fucosidosis,
Erythromelalgia can be similar to those of Fabry disease. Thus Comparisons may
be useful for a differential diagnosis.
What is Fabry
Disease Treatment?
Treatment of Fabry disease focuses on medications that
improve the patient’s quality of life. Pain relievers, including Tegretol and
Dilantin, are used to combat episodes of intense pain. Gastrointestinal problems
may be remedied with pancrelipase. Heart and anti-clotting medications may be
used along with pacemakers to prevent heart attacks. Angiotensin-converting
enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) are used to
combat kidney disease, enzyme replacement therapies that give patients forms of
alpha-galactosidase, the enzyme they are missing.
