Pseudoxanthoma elasticum, PXE, is an inherited disorder caused by mutations in the ABCC6 transporter gene that affects connective tissue in some parts of the body. Elastic tissue in the body becomes mineralized; that is, calcium is deposited in the tissue.
Pseudoxanthoma elasticum (PXE), also known as Grönblad–Strandberg syndrome, is a genetic disease that causes fragmentation and mineralization of elastic fibers in some tissues. The most common problems arise in the skin and eyes, and later in blood vessels in the form of premature atherosclerosis.

There are no prenatal tests to determine whether the fetus has PXE. PXE is an inherited disorder caused by changes (mutations) in the ABCC6 transporter gene. ABCC6 is one of a group of genes that transport certain molecules back and forth across cell membranes.

Pseudoexfoliation (PXF) syndrome is characterized by the deposition of distinctive fibrillar material in the anterior segment of the eye. It is an age-related process that is associated with open and narrow angle glaucomas and the formation of cataracts.
Pseudoexfoliation glaucoma, or pseudoexfoliative glaucoma, is the same condition with the addition of elevated eye pressure and evidence of damage to the optic nerve. Pseudoexfoliation is not to be confused with “true exfoliation”, which is due to heat or infrared exposure (and which can be found among glassblowers).
Pseudoexfoliation syndrome (PXF or PEX) is an age-related systemic syndrome that targets mainly ocular tissues through the gradual deposition of fibrillary white flaky material from the lens, mainly on the lens capsule, ciliary body, zonules, corneal endothelium, iris and pupillary margin.

Individuals with PXE should make periodic visits to their physician for monitoring of blood pressure, cholesterol, and pulses in the arms and legs. A heart-healthy lifestyle is recommended, with low-fat foods and plenty of exercise. Consistent exercise may decrease the effects of PXE on the blood vessels.
Since the identification of mutations in the ABCC6 transporter gene as the cause of PXE, analysis of blood can be performed in research centers to confirm the presence or absence of mutations. Eyes: PXE affects the retina of the eye.
Certain effects of PXE can cause serious medical problems, while others have less impact. Effects may include: skin changes, changes in the retina of the eye that may result in significant loss of central vision, changes in the cardiovascular system that may involve calcification of arteries and decreased blood flow in the arms and legs, and/or changes in the gastrointestinal system that may lead to bleeding in the stomach or intestines. At present, there is no way to predict the exact progression of the disorder for a particular individual. Some people have no skin lesions; others have no vision loss. Many people do not experience gastrointestinal complications or cardiovascular difficulties. A few have no manifestations of PXE except for a positive skin biopsy or irregular streaks resembling a blood vessel (angioid) in the retina of the eye. The effects of PXE and its rate of progression seem to have no discernible pattern.
Gastrointestinal system: Uncommonly, PXE may cause gastrointestinal bleeding. This is sometimes not recognized immediately and can be life-threatening. Little is known about the gastrointestinal effects of PXE, except that the bleeding is usually widespread in the stomach and/or intestines. In a few patients, this bleeding has been mistaken for ulcers. A person with PXE experiencing any gastrointestinal difficulty should be sure to tell the attending physician that he or she has PXE. Some physicians recommend that affected individuals avoid non-steroidal, anti-inflammatory medications, such as aspirin, ibuprofen, and naproxen.
Some people have no skin lesions; others have no vision loss. Many people do not experience gastrointestinal complications or cardiovascular difficulties. A few have no manifestations of PXE except for a positive skin biopsy or irregular streaks resembling a blood vessel (angioid) in the retina of the eye.
Some of these effects may be alleviated by reconstructive, or plastic, surgery. It is possible to have PXE and not have any apparent skin lesions. In some individuals, careful examination of the skin by a dermatologist does not reveal any visible sign of lesions, but a positive biopsy indicates the diagnosis of PXE.
Individuals with PXE have distinctive skin lesions, changes of blood vessels, and eye abnormalities. These may vary in distribution and severity
The basic fault in PXE appears to relate to genetic abnormalities on chromosome 16p13.1. The disease involves the transporter genes MRP6 or ABCC6 in at least some affected families. There is good evidence that collagen and ground substance are abnormal in affected individuals.
Pseudoxanthoma elasticum (PXE) is the name given to a group of connective tissue disorders that affect the elastic tissue of the skin, blood vessels, and the eyes. PXE is also known as Gronblad-Strandberg syndrome.
The diagnosis of PXE is usually straightforward on skin biopsy. The pathology of PXE is characteristic.
PXE affects about 1 in every 160,000 people. There are a number of subtypes of PXE, each with a slightly different clinical presentation and pattern of inheritance. Two are inherited as an autosomal dominant characteristic; this means half the children of an affected individual are affected.
The common sites affected in PXE are the sides of the neck, below the collar bones, the armpits, abdomen, groins, perineum and thighs.
Obstetric risk associated with pseudoxanthoma elasticum. Patients with PXE have an increased risk of miscarriage in the first three months of pregnancy. Stretch marks develop during pregnancy in virtually all patients.
Pseudoxanthoma elasticum, PXE, is an inherited disorder that causes calcium and other minerals to accumulate in the elastic fibers of the skin, eyes, and blood vessels, and less frequently in other areas such as the digestive tract. PXE may cause the following symptoms: growth of yellowish bumps on the skin of the neck, under the arms, ...
PXE may cause the following symptoms: growth of yellowish bumps on the skin of the neck, under the arms, or in the groin area; reduced vision; periodic weakness in the legs ( claudication ); or bleeding in the gastrointestinal tract, particularly the stomach.
Eighty percent of individuals affected with PXE are found to have mutations in the ABCC6 gene by the genetic testing currently available. [1] . Once the ABCC6 mutations that cause PXE in a family are identified, unaffected relatives may be tested for the familial mutations to determine whether or not they are carriers.

PXE BaseCode and UNDI runtime modules are copied from FLASH or upper memory into the top of free base memory between 480K (78000h) and 640K (A0000h). This memory must be zero-filled by the system BIOS. If this memory is not zero-filled, the relocation code in the PXE ROMs will assume that this memory is being used by the system BIOS or other boot ROMs.

Medical genetics. Pseudoxanthoma elasticum ( PXE) is a genetic disease that causes mineralization of elastic fibers in some tissues. The most common problems arise in the skin and eyes, and later in blood vessels in the form of premature atherosclerosis.
PXE first affects the retina through a dimpling of the Bruch membrane (a thin membrane separating the blood vessel-rich layer from the pigmented layer of the retina ), that is only visible during ophthalmologic examinations. This is called peau d'orange (a French term meaning "skin of the orange").
The reported prevalence of pseudoxanthoma elasticum is about 1:25,000. Females are twice as likely to be affected as males. The disease occurs in all ethnicities, but Afrikaners are more likely to have PXE as a result of a founder effect (i.e., higher prevalence in the small group of people from whom Afrikaners descend).

The protein is expressed in most organs, but mainly in the liver and kidney. ABCC6 mediates ATP release in the liver. This is the main source of circulating pyrophosphate (PPi), and individuals affected by PXE have strongly reduced plasma PPi levels, explaining their mineralization disorder.
PXE may affect the gastrointestinal and cardiovascular systems. Gastrointestinal bleeding is a rare symptom and usually involved bleeding from the stomach. In the circulatory system, intermittent claudication, a condition in which cramping pain in the leg is induced by exercise, is a prominent feature.
