Mutations in the WRN gene are found in about 90% of people with Werner syndrome. Saunders Co., 2011. Children with Werner syndrome often appear unusually thin and, during late childhood, have an unusually slow growth rate.

In addition, according to several investigators, urine tests may reveal elevated levels of hyaluronic acid, a complex carbohydrate that is present in the spaces between certain cells (intercellular spaces) within certain connective tissues. In some affected arteries, there may be abnormal accumulations of calcium deposits within the middle coat (tunica media) of the arteries and progressive destruction and replacement of the arteries muscle and elastic fibers with fibrous tissue (Monckebergs arteriosclerosis).

Werner syndrome is also typically characterized by the premature onset of senile cataracts, a condition in which there is loss of transparency of the lenses of the eyes. Die Behandlung beschrnkt sich auf die Prophylaxe und Therapie der Komplikationen. 2019 Die meisten Patienten sterben vor dem 50. By approximately 25 years of age, individuals with Werner syndrome also develop progressive skin changes, particularly affecting the facial area, the upper arms and hands, and the lower legs and feet (distal extremities).

The University maintains an international registry that collects and distributes clinical information and samples for investigative research. Available at Accessed June 18, 2018.

Screening recommendations may change over time as new technologies are developed and more is learned about Werner syndrome.

In addition, there is absence of the growth spurt typically seen during adolescence. Lauper JM, Krause A, Vaughan TL, Monnat RJ Jr. This protein also assists in the process of copying (replicating) DNA in preparation for cell division.

Die Patienten erscheinen bereits in frhem Erwachsenenalter alt, sie weisen eine dnne, durchscheinende Haut (Dystrophie) auf, die mit zunehmendem Alter verkalkt; es kommt zum Verlust von Unterhautfettgewebe und Pigmentierung. It allows people who carry a specific known genetic mutation to reduce the likelihood that their children will inherit the condition. This means that both parents must pass on a gene mutation for a child to be affected. The rest are likely caused by gene mutations that have not yet been discovered by researchers. In other cases, the voice may be squeaky or unusually hoarse. However, this is a complex procedure with financial, physical, and emotional factors to consider before starting.

Werner syndrome is also characterized by severe, progressive, often widespread thickening and loss of elasticity of artery walls (arteriosclerosis). What are my options for cancer screening?

Some physicians report that individuals with Werner syndrome may have a significantly increased risk of separation of surgical wound layers (wound dehiscence) and/or other complications (e.g., corneal endothelial decompensation). The primary symptoms of this disorder are those associated with the aging process. Progressive arteriosclerosis may lead to episodes of chest pain due to deficient oxygen supply to heart muscle (anginal attacks); progressive inability of the heart to effectively pump blood to the lungs and the rest of the body (heart failure); localized loss of heart muscle caused by interruption of its blood supply (myocardial infarction or heart attack); and/or other potentially life-threatening complications. In addition, skin of the palms, of the soles, and overlying certain prominent joints, such as the elbows and knees, may become unusually thickened (hyperkeratosis) and tend to develop ulcers due to destruction of surface tissues. Both males and females with Werner syndrome may be affected by hypogonadism.

Please note that NORD provides this information for the benefit of the rare disease community.

According to reports in the medical literature, diabetes mellitus is typically mild and may often be managed with dietary changes and appropriate medications by mouth to decrease elevated sugar (glucose) levels in the blood (oral hypoglycemic medications). syndrom

One of the most significant health problems faced by people with Werner syndrome is the early development of various types of cancer and atherosclerosis, commonly known as hardening of the arteries, which can lead to a heart attack.

In some cases, other abnormalities of the eyes may also be present, such as an accumulation of calcium deposits within the transparent region in the front of the eyes (corneal calcification), inflammation of the middle and innermost layers of the eyes (chorioretinitis), degeneration of the nerve cells (rods and cones) of the retina that respond to light (retinitis pigmentosa), and/or progressive degeneration of the central region of the retina (senile macular degeneration).

Werner Syndrome. As Werner syndrome progresses, affected individuals may develop disorders of aging early in life, such as cloudy lenses (cataracts) in both eyes, skin ulcers, type 2 diabetes, diminished fertility, severe hardening of the arteries (atherosclerosis), thinning of the bones (osteoporosis), and some types of cancer.

The risk of cancer is increased in people who have Werner syndrome, but the specific risk of cancer is unknown. Diese Seite wurde zuletzt am 22.

For example, in those with episodes of chest pain due to deficient oxygen supply to heart muscle (anginal attacks), treatment may include the use of certain medications that may help to minimize or manage such symptoms. Individuals with this disorder typically grow and develop normally until they reach puberty.

Progressive arteriosclerosis, malignancies, and/or associated abnormalities may result in potentially life-threatening complications by approximately the fourth or fifth decade of life. (For more information on this disorder, choose Gottron as your search term in the Rare Disease Database.

More than 80 different mutations of the WRN gene have been identified in individuals with the disorder.

Werner Syndrome.

Eventually the capillaries may become obstructed. In addition, thorough cardiac evaluations and ongoing monitoring may also be performed (e.g., clinical examinations, X-ray studies, specialized cardiac tests) to assess associated cardiovascular abnormalities and determine appropriate disease management.

Werner syndrome is estimated to affect 1 in 200,000 individuals in the United States.


Due to progressive arteriosclerosis, malignancies, and/or other associated abnormalities, many individuals with Werner syndrome may experience life-threatening complications by approximately the fourth or fifth decade of life. From infancy on, children with this disorder appear older than their actual age.

Mutations in the WRN gene often lead to the production of an abnormally short, nonfunctional Werner protein.

Synonyme sind: Progeria adultorum, Rabbiosi-Syndrom; englisch adult progeria, Beim autosomal-rezessiv vererblichen Werner-Syndrom liegt ein Defekt des WRN-Gens (auch RecQL2 genannt) auf dem kurzen Arm von Chromosom 8 (p12-p11.2) vor, das fr eine DNA-Helikase der RecQ-Familie codiert.

In individuals with Werner syndrome, measures to manage arteriosclerosis and associated cardiovascular abnormalities are symptomatic and supportive.

Due to the risk of skin cancer, people with Werner syndrome should also limit sun exposure and protect themselves from sunlight when outside. This means that the risk of Werner syndrome can be passed from generation to generation in a family. Werner syndrome is a rare disorder that affects males and females in equal numbers.

A person who has only 1 copy of the gene mutation is called a "carrier." Storm syndrome (Werner-like syndrome) is an extremely rare inherited disorder associated with premature aging and heart disease.

JOURNAL ARTICLES Oshima J, Sidorova JM, Monnat RJ Jr. Werner syndrome: Clinical features, pathogenesis and potential therapeutic interventions. Affected areas may be prone to developing open sores (ulcers) due to decreased supply of oxygenated blood to tissues (ischemia).

Researchers have also observed a high frequency of chromosomal abnormalities (e.g., random translocations) in cultured skin cells (fibroblasts) and cultured white blood cells (lymphocytes) derived from certain cell lines (clones) in individuals with Werner syndrome. Other symptoms may include unusual flexibility of the small joints, a forehead that protrudes outward (frontal bossing), and/or short stature. Epub 2016 Mar 15. Review. However, in those with Werner syndrome, the condition may become apparent by about age 35. Other symptoms during adolescence may include the loss of eyebrows and eyelashes, and the thinning and graying of scalp hair.

Erratum in: Geriatr This form of diabetes usually develops in normal individuals of approximately 50 to 60 years. The risk is the same for males and females.

The WRN gene provides instructions for producing the Werner protein, which is thought to perform several tasks related to the maintenance and repair of DNA. The skin is unusually thin and parchment-like on the hands and feet.

As a result, affected males usually have an unusually small penis and small testes.

In some cases, specialized laboratory tests may be performed on cultured skin cells (fibroblasts) from affected individuals, demonstrating abnormally decreased replication of Werner syndrome fibroblasts. The chance for a child to receive normal genes from both parents is 25%. Specialized imaging studies and laboratory tests may be conducted to detect, confirm, or characterize certain abnormalities potentially associated with the disorder.

NORD is not a medical provider or health care facility and thus can neither diagnose any disease or disorder nor endorse or recommend any specific medical treatments. The symptoms of this disorder are similar to those of Werner syndrome and include the loss of the fatty layers on the arms and legs, a beak-like nose, a small jaw, and/or a narrow mouth. Arthritis often affects bone joints during childhood and adolescence. Lebensjahr. In addition, those with this form of diabetes may be susceptible to diabetic coma due to severely reduced levels of fluid within cells (hyperosmolar nonketotic coma).

The WRN gene encodes for a helicase protein, suggesting that impaired DNA metabolism is involved in the premature aging seen in individuals with the disorder.

Contact a health care provider if you have questions about your health. If cataracts are detected, an illuminated microscope (slit lamp) may be used to examine the internal structures of the front regions of the eyes, enabling ophthalmologists to determine the specific location and extent of the cataracts.

Approximately 70 percent of affected individuals have develop non-insulin-dependent (or type II) diabetes mellitus at the time of diagnosis. Other symptoms may include underdeveloped teeth and nails, unusually small hands and feet, malformed or missing thumbs, and/or sparse and prematurely gray hair or baldness. Werner syndrome is inherited in an autosomal recessive pattern, which means both copies of the WRN gene in each cell have mutations. 188-201.

The disorders frequency has been estimated at one to 20 per one million individuals in the United States.

The most common neoplasms in Werner syndrome are carcinomas of thyroid, followed by cancers of the pigment-producing cells in skin and mucosa (malignant melanoma), cancer of the protective membranes surrounding the brain and the spinal cord (meningioma), tumors that arise within the soft tissues and bones (sarcomas and osteosarcoma), soft tissue sarcomas, primary bone tumors and leukemia/myelodysplasia. What are the different ways a genetic condition can be inherited?

Options exist for people interested in having a child when a prospective parent carries a gene mutation that increases the risk for this hereditary cancer syndrome. and are distinct from normal epigenetic aging processes. The spectrum of WRN mutations in Evidence also suggests that the altered protein is broken down more quickly in the cell than the normal Werner protein. It is not uncommon for affected individuals to develop multiple, rare cancers during their lifetime.

Common features of Werner syndrome (diagnosed after age 10): Skin changes associated with aging, such as wrinkling, thinning, tightnening, ulcers, dryness, discoloration, bruising, Characteristic facial features, including wrinkling and loss of muscle tone, Positive 24-hour urine hyaluronic acid test, Problems with fertility (the ability to have a child), Early atherosclerosis, meaning plaque buildup in arteries.

Many individuals with Werner syndrome also have additional skin abnormalities.

This is because a genetic mutation was known to occur many generations ago, when their population was smaller in number, and over time the genetic mutation has been passed down repeatedly, affecting a higher number of people; this is called a founder mutation. Also, the altered protein may allow DNA damage to accumulate, which could impair normal cell activities and cause the health problems associated with this condition. Arteriosclerosis of peripheral blood vessels may cause or aggravate skin wasting (atrophy) and ulceration In addition, abnormal calcium deposits may accumulate within certain heart valves, such as the valve situated where the bodys major artery (aorta) arises from the lower left chamber of the heart (aortic valve) and the valve located between the left upper and lower heart chambers (mitral valve). Werner syndrome is caused by abnormal changes (mutations) in the WRN gene. Opresko PL, Calvo JP, von Kobbe C. Role for the Werner syndrome protein in the Deep ulcerations around Achilles tendons and, less frequently, at elbows, are highly characteristic to Werner syndrome.

Aufgrund der hohen Mutationsrate werden bei Patienten mit Werner-Syndrom hufig maligne Tumoren (im Gegensatz zu den Tumoren des normalen Alterns vor allem Sarkome) beschrieben, die neben den Komplikationen der arteriosklerotischen Vernderungen (Myokardinfarkt, Apoplexie) blicherweise lebenslimitierend sind.

Types of cancers reported in people with Werner syndrome include thyroid cancer, melanoma on the skin, soft tissue sarcoma, and osteosarcoma (a type of bone cancer). Some females with the disorder may fail to develop secondary sexual characteristics (e.g., appearance of axillary and pubic hair, breast development, menstruation) and have poorly developed genitals.
