A cure for Werner syndrome has not yet been discovered. Werner syndrome (progeria of the adult) is a rare autosomal recessive disorder that results from mutations in the WRN gene, which encodes Werner protein, a DNA helicase enzyme that maintains genomic stability. Hisama FM, Kubisch C, Martin GM, Oshima J. [32], Evidence was presented that WRN protein plays a direct role in the repair of methylation induced DNA damage. [33], Mutations which cause Werner syndrome all occur at the regions of the gene which encode for protein, and not at non-coding regions. Goto M, Ishikawa Y, Sugimoto M, Furuichi Y. Werner syndrome: a changing pattern of clinical manifestations in Japan (1917~2008). [18], On the episode "Stargazer in a Puddle" from the television series Bones, the victim has Werner syndrome, the team discovering in the course of the investigation that her mother killed her daughter because she was dying of another disease and worried that her daughter would have nobody to look after her afterwards, with the tragic twist that the mother began to recover from her disease after her daughter's death. Human progeroid syndromes are linked with mutations in single genes accelerating some, but not all, features of normal aging. In addition to telomere dysfunction, over-expression of oncogenes and oxidation can induce this type of response. [Medline]. A polymorphism in Werner syndrome gene is associated with breast cancer susceptibility in Chinese women. This syndrome occurs more often in Japan, affecting 1 in 20,000 to 1 in 40,000 people. [Medline]. It affects both sexes equally and all races. Saha B, Lessel D, Nampoothiri S, Rao AS, Hisama FM, Peter D, et al. The average age of patients at the time of diagnosis is 37 years. This drug has shown to revert the aged characteristics of young WS cells to those seen in normal, young cells and improve the lifespan of WS cells in vitro.

WRNp also physically interacts with p53, a tumor suppressor gene that stops the formation of tumors and the progression of cancers,[27] which inhibits the exonuclease activity of the WRNp. Otto Werner originally defined Werner syndrome (WS) in 1904 on the basis of sclerodermalike, thin, tight skin and bilateral cataracts. 2014 Mar 12. Please confirm that you would like to log out of Medscape. Lyons C, Gallagher D, McSwiney T, McElnea E, Kinsella F. The ophthalmic diagnosis and management of four siblings with Werner syndrome. This is also generally the earliest observed symptom, with hair loss occurring first on the scalp and the eyebrows. However, a child may have characteristics of WS but with no identifiable mutation in the WRN gene. 2009 Feb 10. [20] Diabetes mellitus is another common accompaniment. Salk Institute researchers discovered that a protein mutated in the premature aging disorder, Werner syndrome, plays a key role in stabilizing heterochromatin, a tightly packaged form of DNA. 2016 Apr 28. 2008 May. WS is the most common of the premature aging disorders. Thus, WRN helicase is important for preventing catastrophic telomere loss during DNA replication. [30], WRN protein participates in a complex with RAD51, RAD54, RAD54B and ATR proteins in carrying out the recombination step during inter-strand DNA cross-link repair. Breast Cancer Res Treat. Characteristic findings on physical examination Werner syndrome (WS) is an autosomal recessive disorder that affects connective tissue throughout the body. [Medline]. Topical treatments can be used for minor ulcers, but are not effective in preventing new ulcers from occurring. Supplementation of vitamin C is suspected to be beneficial in the treatment of human Werner syndrome, although there was no evidence of anti-aging activity in nonmutant mice. In contrast with the normal population, the rate of osteoporosis is especially high for male patients. WS is also known as progeria adultorum, progeria of the adult, and pangeria. Pirzio LM, Pichierri P, Bignami M, Franchitto A. Werner syndrome helicase activity is essential in maintaining fragile site stability. [1], Progeria can also refer to Hutchinson-Gilford syndrome, which is described as a lamin A gene defect and has onset early in life. Pregnancy complicated by Werner syndrome. [6], Skin fibroblasts in WS patients demonstrate characteristics of cells in conditions of stress with slow growth rates, an elongated cell cycle, and an altered morphology that suggests stress-induced premature senescence transduced in part by the p38α MAP kinase signaling pathway. 2005 Nov. 4(4):579-602. Lauper JM, Krause A, Vaughan TL, Monnat RJ Jr. 2010 Jan. 24(1):158-72. Ann N Y Acad Sci. [20] Prior to 1996, Werner syndrome was thought to be a model for accelerated aging. SB203580 is in the clinical trial stages, and the same results have not yet been seen in vivo. Thus, RecQ helicases are important for maintaining DNA stability, and loss of function of these helicases has important implications in the development of Werner syndrome. Wendelin Werner (b. 24(1):68-72. [18] Patients are also generally short-statured due to absence of the adolescent growth spurt. [19] The most common symptom of the six is premature graying and loss of hair. Werner syndrome with refractory cystoid macular edema and immunohistochemical analysis of WRN proteins in human retinas. [Medline]. Bloom syndrome has also appeared in the older literature as Bloom–Torre–Machacek syndrome. Genet Couns. The accumulation of these damaged cells due to telomere shortening over many years may be indicative of why Werner syndrome symptoms only appear after an individual is about twenty years old.[41]. [31] X4L4 stimulates WRN exonuclease activity that likely facilitates DNA end processing prior to final ligation by X4L4. Long Duration Response in Parkinson's Disease: Levodopa Revisited, Comparing Two Facets of Emotion Perception Across Multiple Neurodegenerative Diseases. Everolimus rescues multiple cellular defects in laminopathy-patient fibroblasts. Kawai T, Nozato Y, Kamide K, Onishi M, Yamamoto-Hanasaki H, Tatara Y, et al. Geriatr Gerontol Int. [15, 16]. In 1997, the gene responsible for Werner’s syndrome … 2002 Dec 2 [Updated 2012 Dec 13]. WRN protein was found to have a specific role in preventing or repairing DNA damages resulting from chronic oxidative stress, particularly in slowly replicating cells. [Medline]. Franklin Flowers, MD is a member of the following medical societies: American College of Mohs SurgeryDisclosure: Nothing to disclose. [34] There are 35 different known mutations of WRN, which correspond to stop codons, insertions, or deletions that result in a frameshift mutation. The most common causes of death for people are associated diseases and complications, especially atherosclerosis and cancer. Evidence was recently presented of a crucial role for a helicase in protecting cells against chromosome breakage at normally occurring replication fork-stalling sites. 1114125-overview Werner’s syndrome is named for Otto Werner, a German scientist who originally described the syndrome in his 1904 doctoral thesis. Oshima J, Martin GM, Hisama FM. Topical treatments can be used for minor ulcers, but are not effective in preventing new ulcers from occurring. Transmission pattern of Werner syndrome; There is a 25% chance that a child born to two parents with … [8] Two novel WRN mutations were described in patients of South Asian ancestry. 58 (7):1033-1036. Most of these mutations result in an abnormally short, nonfunctional Werner protein. Such cases are classified as atypical WS. The aging process involves increasing errors in the mitotic machinery of dividing cells in the postreproductive stage of life; therefore, WS serves as a model for studying the aging process in vivo and in vitro. [Full Text]. Other associated skin conditions include ulcers,[19] which are very difficult to treat in Werner syndrome patients, and are caused in part by decreased potential of skin cells for replication. He noticed these symptoms particularly in a family with four sequential children who all showed the characteristics of the syndrome at around the same age. [11] A paper from 2010 reported 18 new mutations, including 2 genomic rearrangements, a deep intronic mutation resulting in a novel exon, a splice consensus mutation leading to utilization of the nearby splice site, and 2 rare missense mutations. Franklin Flowers, MD Professor Emeritus, Department of Dermatology, Affiliate Associate Professor of Pathology, University of Florida College of Medicine Anna Wozniacka, MD, PhD Professor, Department of Dermatology, Medical University of Lodz, Poland 1(1):7-14. https://profreg.medscape.com/px/getpracticeprofile.do?method=getProfessionalProfile&urlCache=aHR0cHM6Ly9lbWVkaWNpbmUubWVkc2NhcGUuY29tL2FydGljbGUvMTExNDEyNS1vdmVydmlldw==. [Medline]. FASEB J. [Medline]. 2019 Apr 1. There are an estimated 350-400 children living with Progeria worldwide at any one time. The skin ulcers that accompany WS can be treated in several ways, depending on the severity. [13] Fragile sites may be DNA regions particularly sensitive to replicative stress. 908:167-79. 1968), French mathematician, winner of the Fields medal (2006) Franz Werner (1867-1939), Austrian herpetologist and entomologist; C. W. Otto Werner (1879-1936), German physician who discovered a premature aging condition he named Werner syndrome; Anton von Werner (1843-1915), German painter; André Werner (b. The skin ulcers that accompany WS can be treated in several ways, depending on the severity. WS is more common in Japan and Sardinia than in other regions. Spectrum and risk of neoplasia in Werner syndrome: a systematic review. Massip L, Garand C, Paquet ER, et al. [19], Werner syndrome patients often have skin that appears shiny and tight, and may also be thin or hardened. [citation needed], In season 1 episode 8 "Cold Comfort" from TV series Dark Angel, a character has a "form of progeria, similar to Werner syndrome", due to genetic manipulation. A model for the study of human aging. [Medline]. Vitamin C supplementation also appeared to normalize several age-related molecular markers such as the increased levels of the transcription factor NF-κB. [42] This finding suggested that WRN may be important in dealing with oxidative DNA damage that underlies normal aging[42] (see DNA damage theory of aging). Salk Institute researchers discovered that a proteinmutated in the premature aging disorder, Werner syndrome, plays a key rolein stabilizing heterochromatin, a … Werner Syndrome Helicase. Werner’s syndrome (WS) is an autosomal recessive genetic disease, which is mainly characterized by scleroderma-like skin changes, juvenile cataracts, short stature, and signs of premature aging. James, William; Berger, Timothy; Elston, Dirk (2005). [31], WRN protein appears to play a role in resolving recombination intermediate structures during homologous recombinational repair (HRR) of DNA double-strand breaks. A novel mutation of the WRN gene in a Chinese patient with Werner syndrome. Novel LMNA gene mutation in a patient with Atypical Werner's Syndrome. [Medline]. Nehlin JO, Skovgaard GL, Bohr VA.

[20], Patients are also at an increased risk of cancer, especially malignant melanoma. This leads to a reduction in DNA repair. ... recently discovered importance of WRN as a … Friedrich K, Lee L, Leistritz DF, et al. It is however later said that Solid Snake's body, created as a genetically engineered clone, had been designed to break down quickly[citation needed], In season 3 episode 9, "The Ballad of Kevin and Tess", of the TV series The 4400, Kevin is said to have Werner syndrome to hide his real condition from the public. [2]. [Medline]. 2010 May 7. The p38 pathway has also been implicated in the anti-inflammatory response that causes atherosclerosis, diabetes, and osteoporosis, all of which are associated with Werner's syndrome. Case of sarcomatoid carcinoma occurring in a patient with Werner syndrome. Clinical utility gene card for: Werner syndrome. [Full Text]. 2002 He noticed features of skin tightness and thickening as well as cataracts in more than one child born in the same family. [26] For example, the WRN protein binds to RPA, which stimulates WRNp's helicase activity. [18] While normal atherosclerosis generally involves the major arteries, smaller arterioles are more likely to be affected. This process likely involves the helicase and exonuclease activities of WRN protein that operate together with DNA polymerase beta in long patch base excision repair. [5] which codes for a member of the RecQ family of DNA helicases. [Medline]. See the images below. 2018 Apr 17. Biogerontology. 2013. Proc Natl Acad Sci U S A. Since the discovery of the gene, it has become clear that the premature aging displayed in Werner syndrome is not the same, on a cellular level, as normal aging. [9][10], Werner syndrome patients exhibit growth retardation, short stature, premature graying of hair, alopecia (hair loss), wrinkling, prematurely aged faces with beaked noses, skin atrophy (wasting away) with scleroderma-like lesions, lipodystrophy (loss of fat tissues), abnormal fat deposition leading to thin legs and arms, and severe ulcerations around the Achilles tendon and malleoli (around ankles). When functioning normally, the WRN gene and associated protein are important for maintaining genome stability. High stress causes a synergistic effect, where WS cells become even more sensitive to agents that increase cell stress and agents that damage DNA. Symptoms generally manifest during the third decade of life and consist of several pathologies, typically observed in much older people. [15], The blood of WS patients exhibits accelerated DNA methylation changes that are similar to those observed in normal aging according to a molecular biomarker of aging known as epigenetic clock. Case report of a long-surviving Werner syndrome patient with severe aortic valve stenosis. [5], It has a global incidence rate of less than 1 in 100,000 live births[6] (although incidence in Japan and Sardinia is higher, affecting 1 in 20,000–40,000 and 1 in 50,000, respectively). 33(3):278-81. Werner syndrome (WS) is a rare disorder. A founder effect is also apparent in Sardinia, where there have been 18 recorded cases of Werner syndrome. Ethnic-Specific WRN Mutations in South Asian Werner Syndrome Patients: Potential Founder Effect in Patients with Indian or Pakistani Ancestry. [44], In 2010, vitamin C supplementation was found to reverse the premature aging and several tissue dysfunctions in a genetically modified mouse model of the disease. [18]. [12]. Vasc Med. Werner’s syndrome is a rare autosomal recessive progeroid syndrome, which is characterized by premature aging. This activation of p38 may play a role in the onset of premature cell aging, skin aging, cataracts, and graying of the hair. Wang Z, Xu Y, Tang J, Ma H, Qin J, Lu C, et al. Werner syndrome (WS) is an uncommon autosomal recessive disorder characterized by premature aging. [citation needed], In an early cutscene from the game Metal Gear Solid 4, Otacon cites "classic Werner syndrome" as the most likely cause of Solid Snake's premature aging, though he goes on to say that testing had been inconclusive. Otto Werner originally defined Werner syndrome (WS) in 1904 on the basis of sclerodermalike, thin, tight skin and bilateral cataracts. [17], Werner syndrome patients are at increased risk for several other diseases, many associated with aging. This p38 involvement has been documented in WS cells. [28] Since WRNp's function depends on DNA, it is only functional when localized to the nucleus. WS is also known as progeria adultorum, progeria of … Most patients live to about fifty years of age. Michael J Wells, MD, FAAD Dermatologic/Mohs Surgeon, The Surgery Center at Plano Dermatology The onset of WS might occur in individuals in their mid teens, or it may be delayed until an individual is as old as 30 years. [7] Apart from causing defects in DNA repair, its aberrant association with p53 down-regulates the function of p53, leading to a reduction in p53-dependent apoptosis and increasing the survival of these dysfunctional cells. 2013 May 1. Studying Werner syndrome to elucidate mechanisms and therapeutics of human aging and age-related diseases. [29], The finding that WRN protein interacts with DNA-PKcs and the Ku protein complex, combined with evidence that WRN deficient cells produce extensive deletions at sites of joining of non-homologous DNA ends, suggests a role for WRN protein in the DNA repair process of non-homologous end joining (NHEJ). 12 (3):2022-2023. A Japanese WS patient was delineated with compound heterozygous WRN mutations, including a novel heterogeneous c.1720+1G>A substitution plus the most frequent heterogeneous c.3139-1G>C substitution among Japanese, yet with no malignancies detected despite the patient being aged 43 years. J Cell Biol. 2014. Robert A Schwartz, MD, MPH is a member of the following medical societies: Alpha Omega Alpha, American Academy of Dermatology, New York Academy of Medicine, Royal College of Physicians of Edinburgh, Sigma Xi, The Scientific Research Honor SocietyDisclosure: Nothing to disclose. This article incorporates public domain text from The U.S. National Library of Medicine, Protection of DNA against oxidative damage. [3] However, many organs in patients with WS prematurely undergo changes that are usually associated with aging. One instance of these consequences involves telomeres. The WRN gene was cloned in 1998 in an attempt to identify the genetic alterations that cause Werner syndrome (WS) [97], a disease first described by Otto Werner, a German medical student, in 1904 [157]. The estimated incidence is 1 case in 1 million individuals. [Medline]. [6][9] The prevalence of rare cancers, such as meningiomas, are increased in individuals with Werner syndrome. In the most severe cases, surgery may be required to implant a skin graftor amputate a limb if necessary. Ratsasan (2018), a Tamil movie, features a young man born with Werner's and is a victim of childhood bullying due to his appearance and has bad experience proposing to a girl, who turns into serial killer and hunts down and kills school girls. [Medline]. Werner Syndrome was first described by Dr. Otto Werner at the Kiel University in 1904 (Werner, 1904). 14:31. Other symptoms include change in voice (weak, hoarse, high-pitched), atrophy of gonads leading to reduced fertility, bilateral cataracts (clouding of lens), premature arteriosclerosis (thickening and loss of elasticity of arteries), calcinosis (calcium deposits in blood vessels), atherosclerosis (blockage of blood vessels), type 2 diabetes, osteoporosis (loss of bone mass), telangiectasia, and malignancies. 2020 Feb 5. Werner syndrome helicase (WRN) was the second member of the RECQ family of DNA helicases to be discovered in humans. Individuals suffering from Werner's syndrome may experience early loss and graying of the hair. The most common causes of death for WS patients are atherosclerosis and cancer. Robert A Schwartz, MD, MPH Professor and Head of Dermatology, Professor of Pathology, Professor of Pediatrics, Professor of Medicine, Rutgers New Jersey Medical School 2000 Jun. Vitamin C restores healthy aging in a mouse model for Werner syndrome. Mitamura Y, Azuma S, Matsumoto D, Takada-Watanabe A, Takemoto M, Yokote K, et al. [35] Cells of affected individuals also have reduced lifespan in culture,[36] have more chromosome breaks and translocations[37] and have extensive deletions. More than 60 mutations in the WRN gene are known to cause Werner syndrome. It is often treated by managing the associated diseases and relieving symptoms to improve quality of life. [9] Affected individuals typically grow and develop normally until puberty; the mean age of diagnosis is twenty-four, often realized when the adolescent growth spurt is not observed. Werner Syndrome Treatment. Geriatr Gerontol Int. More generally, the findings suggest that heterochromatin disorganization may be a … 2010 May 5. Adroit medical management may enhance life expectancy; one patient was described who survived until dying of acute heart failure at age 68 years. [14] At the level of gene expression, WRN protein deficiency causes changes in the pattern of gene expression that markedly resemble those of normal old age. 2012 Jan 18. [39], Without the WRN protein, the interwoven pathways of DNA repair and telomere maintenance fail to suppress cancer and the aging symptoms seen in patients with WS. Eur J Hum Genet. Ageing Res Rev. Werner’s syndrome was first described in 1904 by Otto Werner in his doctoral thesis, “Uber Katarakt in Verbindung mit Sklerodermie” (“Cataract in combination with scleroderma”) (137). [Medline]. Werner syndrome is a segmental progeroid syndrome whose presentation resembles accelerated aging. Research suggests that this shortened protein is not transported into the cell's nucleus, where it normally interacts with DNA. Patients also display decreased fertility. 128355-overview 22 (3):246-247. [Medline]. Diseases commonly associated with Werner syndrome such as diabetes and cancer are treated in generally the same ways as they would be for a non-Werner syndrome individual. A cure for Werner syndrome has not yet been discovered. An Pediatr (Barc). [3], Werner syndrome is named after the German scientist Otto Werner. Lautrup S, Caponio D, Cheung HH, Piccoli C, Stevnsner T, Chan WY, et al. No mental retardation is observed. Zhao N, Hao F, Qu T, Zuo YG, Wang BX. [21] WRNp is active in unwinding DNA, a step necessary in DNA repair and DNA replication. Genome instability activates stress kinases, implying that kinase inhibitors may form the basis of antiaging therapies for individuals with WS. DuBose AJ, Lichtenstein ST, Petrash NM, Erdos MR, Gordon LB, Collins FS. It is caused by mutations in the WRN gene, which encodes a member of the RECQ family of DNA helicases and has a role in DNA repair. Death usually occurs when patients are aged 30-50 years because of atherosclerosis or malignant tumors. Davis T, Brook AJ, Rokicki MJ, Bagley MC, Kipling D. Evaluating the Role of p38 MAPK in the Accelerated Cell Senescence of Werner Syndrome Fibroblasts. Advanced Parkinson Disease: Are We Breaking New Ground? The mean survival for patients with Werner syndrome (WS) is 46 years. Aging (Albany NY). 2015 Jul 29. 277700 - WERNER SYNDROME; WRN Chromosomal Instability in Werner Syndrome 'Variegated translocation mosaicism' was the designation proposed by W. W. Nichols (Hoehn et al., 1975) for a phenomenon he and others observed in cells from patients with Werner syndrome: skin fibroblast cell lines were usually composed of one or several clones, each marked by a distinctive, apparently … European Academy of Dermatology and Venereology, Sigma Xi, The Scientific Research Honor Society. [22], Approximately 90% of individuals presenting Werner syndrome have any of a range of mutations in the gene, WRN, the only gene currently attributed to cause Werner syndrome. [Medline]. [19], Symptoms become apparent in the late teens and early twenties and continue to progress. License: CC BY-SA, uploaded by Cburnett . This condition was first described by Dr. Otto Werner at the University of Kiel, Germany, in 1904 when he was a medical student. [39] In a normal cell, the telomeres (the ends of chromosomes) undergo repeated shortening during the cell cycle, which can prevent the cell from dividing and multiplying. With an appropriate treatment, her condition seems to be stabilized. This drug targets the p38 signaling pathway, which may become activated as a result of genomic instability and stalled replication forks that are characteristic mutations in WS. 115 (16):4206-4211. Barrios Sanjuanelo A, Munoz Otero C. [Atypical Werner syndrome: Atypical progeroid syndrome: A case report.]. [34] Furthermore, mutated proteins are more likely to be degraded than normal WRNp. As a result, WS cells show a drastic reduction in replicative lifespan and enter into a stage of aging prematurely. Since the disorder was originally described in the medical literature in 1904 (O. Werner), more than 800 cases have been reported. BMC Ophthalmol. [28] WS has been classified as a member of the RecQ family of DNA helicases implicated in the resolution of DNA structures leading to the stall of replication forks. If skin ulcers become badly infected or develop gangrene, they often require amputation. The protein is likely to be involved in the response to DNA damage during replication, as well as in the replication and transcription processes. The disease gets its name from the German scientist Otto Werner. A change in diet and exercise can help prevent and control arteriosclerosis, and regular cancer screenings can allow for early detection of cancer. Between 1934 and 1941, two internists from New York, Oppenheimer and Kugel, coined the term "Werner Syndrome," igniting a wave of interest and research on the disease. 2008 Jan 28. [Medline]. [4] In vivo aging is linked with accelerated aging of fibroblasts in culture, possibly due to the genomic instability, a hallmark of WS. [21] WRN may reactivate replication by preventing unwanted recombination processes from occurring or by promoting recombination, depending on the type of DNA damage. [10], The collagenase level is also increased several times. What are the symptoms of Werner Syndrome? This syndrome represents an important model for aging, possibly allowing improved understanding of mechanisms and therapeutics of human aging. Psoriasis Clinical Practice Guidelines (AAD/NPF, 2021), A Vegan Hiker With a Rash Self-Treated With Coconut Oil, New Brodalumab Psoriasis Outcome Data Suggests That Intermittent Treatment Is As Effective As Continuous Dosing, Swedish Registry Study Finds Atopic Dermatitis Significantly Associated With Autoimmune Diseases. [45] In general, treatments are available for only the symptoms or complications and not for the disease itself. [16], The mutation in the WRN gene that causes Werner syndrome is autosomal and recessive, meaning that sufferers must inherit a copy of the gene from each parent. 2019 Jan 21. A case of Werner syndrome without metabolic abnormality: implications for the early pathophysiology. Mol Genet Genomic Med. J Invest Dermatol. [11] The median and mean ages of death are 47–48 and 54 years, respectively. Battle of the Sexes: Who Gives Better Medical Care? Kyng KJ, Bohr VA. Gene expression and DNA repair in progeroid syndromes and human aging. 2009 Mar. In: Pagon RA, Bird TD, Dolan CR, et al., editors. Acta Obstet Gynecol Scand. [17] Diagnosis is based on six cardinal symptoms: premature graying of the hair or hair loss, presence of bilateral cataracts, atrophied or tight skin, soft tissue calcification, sharp facial features, and an abnormal, high-pitched voice. [21] It is possible nervous system disorders are associated. 2007 Apr. International Registry of Werner Syndrome / Home. 1100:455-69. Ann N Y Acad Sci. Clin Exp Dermatol. Many of these cases have occurred in Japan, where a founder effect has caused a higher incidence rate than in other populations. [20] Soft-tissue sarcomas are the most common cancer types. GeneReviews™ [Internet]. The disease is connected with excessive synthesis of collagen types I and III, which is dependent on elevated messenger RNA (mRNA) levels.
