History Clinicians taking the history of a patient with Beckwith-Wiedemann syndrome should note any family history of childhood cancer, hemihypertrophy, macroglossia, or other clinical. Each year an estimated 11,000 children worldwide are born with BWS. Clin Genet. In fact, it is estimated that those with hemihyperplasia may have a much higher risk, up to 4 times greater, than people with BWS without hemihyperplasia. Kilby MD, Krajewska-Walasek M, Kratz CP, Ladusans EJ, Lapunzina P, Le Bouc Y, How can gene variants affect health and development? Kidney stones have been reported to occur in adolescents and adults with BWS. Skorka A, Tatton-Brown K, Tenorio J, Tortora C, Gronskov K, Netchine I, Hennekam 2019 Dec;181(4):693-708. doi: 10.1002/ajmg.c.31740. The clinical presentation is highly variable, and some cases lack the characteristic features originally described by Beckwith and Wiedemann [ 2,3 ]. However, in patients with Beckwith-Wiedemann syndrome, different parts of this process can be changed. Our patients exhibited a higher incidence of tumor development (21%) than that previously reported, underlying the care with which such patients should be followed, when particular clinical features are observed: visceromegaly affecting three organs (liver, kidney, spleen), and also family history with sign of BWS such as macroglossia, omphalocele, hemihypertrophy, embryonic tumor), high body weight at birth (> or = +2 standard deviations and diastasis recti. The most common tumor types are: Wilms tumor (kidney tumor; about 40% of cases. There can be differences in this expression as well from person to person, including both copies being expressed or neither copy is expressed. Disease Ontology: 11 A syndrome characterized by overgrowth (macrosomia), an increased risk of childhood cancer and congenital malformations. Med Pediatr Oncol. Epigenetic and genetic alterations of the imprinting disorder Beckwith-Wiedemann syndrome and related disorders. An enlarged tongue and abdominal wall defect, primarily omphalocele, are also considered to be common features. The 11p overgrowth spectrum is defined as overgrowth and other features associated with genetic changes at a specific chromosomal region known as 11p, the same region that causes Beckwith-Wiedemann syndrome. European Journal of Human Genetics 2019; 27(4):663-668. This gene provides instructions for making a protein that helps control growth before birth. For example, ultrasound imaging may allow assessment of organ size and overall size of the developing fetus and potentially reveal other findings that may be suggestive of BWS. Mussa A, Russo S, De Crescenzo A, Freschi A, Calzari L, Maitz S, Macchiaiolo M, Molinatto C, Baldassarre G, Mariani M, Tarani L, Bedeschi MF, Milani D, Melis D, Bartuli A, Cubellis MV, Selicorni A, Cirillo Silengo M, Larizza L, Riccio A, Ferrero GB. Please note that NORD provides this information for the benefit of the rare disease community. A Beckwith-Wiedemann Registry was established to coordinate research efforts into Beckwith-Wiedemann syndrome. J Med Genet. These patients should be referred to appropriate specialists. Epub 2007 Mar 6. Patients with cardiac, gastrointestinal, and renal abnormalities may require certain medications, surgery, or other medical interventions. IGF2 is a growth factor. 5th ed. The most common are: Wilms tumor, a kidney cancer. Other signs may include abdominal organs that jut out into the . Beckwith-Wiedemann Syndrome. This means that a parent with a gene mutation may pass along a copy of their normal gene or a copy of the gene with the mutation. Federal government websites often end in .gov or .mil. doi: 10.1002/(sici)1096-911x(199706)28:6<411::aid-mpo3>3.0.co;2-j. The major features of BWS, macrosomia and macroglossia, are often present at birth. However, some genes are turned off or preferentially silenced based upon which parent that gene came from (a process known as genomic imprinting). 10.1002/ajmg.a.30729. Beckwith-Wiedemann syndrome (BWS) is a congenital growth disorder, which means it's present at birth. The improper imprinting of these two regions leads to the improper expression of the genes located within the regions, playing a role in the development of BWS. government site. Some patients with significant lateralized overgrowth of the limbs may require shoe lifts and in some cases, surgical correction may be needed. Abnormal enlargement of one side or structure of the body (lateralized overgrowth) may occur, resulting in asymmetric growth. Brioude F, Lacoste A, Netchine I, Vazquez MP, Auber F, Audry G, Gauthier-Villars M, Brugieres L, Gicquel C, Le Bouc Y, Rossignol S. Horm Res Paediatr. Patients with ICR1-GoM and UPD should undergo renal ultrasonography scanning, given their risk of Wilms tumor. These microdeletions appear to cause BWS when inherited maternally; when inherited paternally, the disorder does not develop. This means that the risk for BWS can be passed from generation to generation in a family. While some suggest that the invasiveness of a regular blood draw may be stressful for many families, AFP has proven to be a useful early indicator for hepatoblastoma. Pediatrics 2017; 140(1). The estimated risk for a tumor in a child with BWS is about 5% to 10%. Normally, every cell has 2 copies of each gene: 1 inherited from the mother and 1 inherited from the father. NCI's Dictionary of Cancer Terms provides easy-to-understand definitions for words and phrases related to cancer and medicine. Some individuals may appear mildly affected while others appear more significantly affected. Genetic testing for gene mutations associated with BWS is available, but it is complex. About Beckwith-Wiedemann Syndrome (BWS): BWS is a condition that affects many parts of the body. NORD Guide to Rare Disorders. 2022 Oct;102(4):314-323. doi: 10.1111/cge.14193. Beckwith-Wiedemann syndrome is associated with an increased risk of cancer, including Wilms tumour , rhabdomyosarcoma , neuroblastoma and In most cases, these genetic changes occur in some but not all of the cells, resulting in mosaicism. ), Adrenocortical carcinoma (about 20% of cases). Negative testing on blood, for example, may not necessarily exclude a diagnosis. Last updated: May;89(5):613-7. doi: 10.1016/j.ygeno.2007.01.005. All rights reserved worldwide, what to expect when having common tests, procedures, and scans. About 14% of patients with BWS have an unknown cause for diagnosis. The parents can then choose to transfer embryos which do not have the mutation. Conclusion: Call our laboratory at 1-800-473-9411 or contact one of our Laboratory Genetic Counselors for assistance. If a tumor develops in association with BWS, the appropriate treatment measures vary depending on the specific tumor present, the stage and/or extent of disease, and/or other factors. Some newborns with BWS may have low blood sugar (neonatal hypoglycemia or hyperinsulinism) due to overgrowth and excessive secretion of the hormone insulin by the pancreas. official website and that any information you provide is encrypted Translocations and inversions can cause additional problems if the places where the chromosomes break (breakpoints) interrupt important genes, or if pieces of the chromosome break off and become lost. This includes chromosomal inversions or rearrangements (translocations) or the presence of extra chromosomal material (duplications). Greater than 80% of children do not develop cancer Risk is most elevated in childhood prior to age 10 Diagnosis BWS is often suspected due to the presence of clinical features with or without hypoglycemia. As such, cardinal features are given two points each in the scoring system. Other treatment is symptomatic and supportive. Colket Translational Research Building, Rm 3028 It is recommend that additional tissue be collected from patients with suspected Beckwith-Wiedemann syndrome, in conjunction with other surgical procedures when possible, so further testing can be done. Additional abnormalities include duplication of the series of tubes and ducts through which the kidneys reabsorb water and sodium (duplicated collecting system), widening of some of the small tubes and collecting ducts (medullary sponge kidney), and the presence of small pouches (diverticula) on the kidneys. What is the prognosis of a genetic condition? Interestingly, loss of imprinting (LOI) at the IGF2 locus has been shown to induce biallelic expression of this mitogenic growth factor in 10% of normal human adults (46) and is implicated in several types of cancer and in Beckwith-Wiedemann syndrome (45), a disease with an array of defects, including several phenotypic and metabolic . Expert For more information on the Registry, contact: Jennifer M. Kalish, MD, PhD consensus document: Clinical and molecular diagnosis, screening and management of Microdeletions of the KCNQ10T1 (LIT1) gene have also been identified in some people with BWS. Beckwith-Wiedemann Syndrome and Silver-Russell Syndrome: A pair of syndromes that impact development. This phenomenon is called imprinting, and is caused by methylation, or a process of marking the DNA to turn certain genes on or off. American Journal of Medical Genetics Part A. genes, and chromosome 11p15.5. Some patients may undergo tongue reduction surgery with the goal of improving breathing, feeding, and jaw or dental malformations due to macroglossia. J Pediatr. Regular orthopedic evaluation is recommended for patients with lateralized overgrowth. Wang KH, Kupa J, Duffy KA, Kalish JM. BWS may also be associated with low blood sugar levels in the first few days of life (neonatal hypoglycemia) or beyond leading to persistent low blood sugars (hyperinsulinism), distinctive grooves in the ear lobes (ear creases and ear pits), facial abnormalities, abnormal enlargement of one side or structure of the body (lateralized overgrowth) resulting in unequal (asymmetric) growth, and an increased risk of developing certain childhood cancers, most commonly Wilms tumor (kidney tumor) and hepatoblastoma (liver tumor). Our observation of a high frequency of germline p53 mutations in children with sporadic ADCC suggests . Beckwith Wiedemann syndrome (BWS) is the most common overgrowth and cancer predisposition disorder. Available from Eur J Hum Genet. Before Results: Several types of childhood tumors, including Wilms tumor (), adrenocortical carcinoma (), and rhabdomyosarcoma (), display a specific loss of maternal 11p15 . doi: 10.1002/mgg3.1796. Affected individuals may not have all of the symptoms listed. Systemic chemotherapy for advanced non-small cell lung cancer. BWS is caused by changes on chromosome 11p15.5 and is characterized by a wide spectrum of symptoms and physical findings that vary in range and severity from person to person. 2021 Oct;9(10):e1796. Hemihypertrophy is often associated with overgrowth syndromes such as Beckwith-Wiedemann syndrome, proteus syndrome, neurofibromatosis Type 1 and mosaic trisomy 8. Mosaic uniparental disomy in Beckwith-Wiedemann syndrome. and transmitted securely. Danbury, CT 06810 Such features may include distinctive slit-like grooves or creases in the ear lobes and dimples on the back of the ears (ear creases or pits), prominent eyes with relative underdevelopment of the bony cavity of the eyes (intraorbital hypoplasia), and/or a prominent back region of the skull (occiput). 2019 Aug 30. doi: 10.1002/ajmg.c.31740. Pediatric Blood & Cancer 2018; 65(10): e27296. Endocrinology: Children with severe hypoglycemia should be evaluated by an endocrinologist, and treatment may be required until this normalizes. Signs include large body size, large tongue, large organs, a defect in the abdominal wall and low blood sugar in newborns. Cooper WN, Luharia A, Evans GA, et al., Molecular subtypes and phenotypic expression of Beckwith-Wiedemann syndrome. This leaves only the paternally expressed IGF2 to promote cell proliferation. These microduplications can also occur randomly (de novo). However, without proper detection and appropriate treatment, neurological complications may result. Embryonal cancers occur in approximately 8% of patients with BWS. Orphanet.

Philadelphia, PA 19104 This risk depends on the genetic cause of the condition. BWS results from various abnormalities affecting the proper expression of genes that control growth within a specific region of chromosome 11(11p15.5). 2005 Jul 1;136(1):95-104. doi: Assisted reproduction techniques and prenatal diagnosis of BeckwithWiedemann spectrum presenting with omphalocele. Bean LJH, Gripp KW, Amemiya A, editors. The errors allow the cells to grow and divide uncontrollably and to go on living when other cells would die. Some children with this condition are born with an opening in the wall of the abdomen (an omphalocele) that allows the abdominal organs to protrude through the belly-button. Beckwith-Wiedemann syndrome: an international consensus statement. Several different tumor types, both cancerous and benign (noncancerous), have been reported in children with BWS. Tumors develop in about 10 percent of people with this condition and almost always appear in childhood. The syndrome was independently described by J.B . 2022 Jul 1;10:905089. doi: 10.3389/fped.2022.905089. Email: [emailprotected], Some current clinical trials also are posted on the following page on the NORD website: It is estimated to occur in 1 in 10,340 individuals in the general population. Beckwith-Wiedemann Syndrome (BWS) is a condition that occurs when parts of the body grow too large, too fast. Variants in the CDKN1C gene prevent this protein from restraining growth, which leads to the abnormalities characteristic of Beckwith-Wiedemann syndrome. http://www.ncbi.nlm.nih.gov/books/NBK1394/. Kalish JM, et al. 2022 Jul 4;13:831452. doi: 10.3389/fgene.2022.831452. 1998;132:398400. Front Pediatr. HHS Vulnerability Disclosure, Help Imprinting center 2 (IC2) is associated with KvDMR, a chemical switch found on the KCNQ1 gene. European Journal of Medical Genetics. MeSH AFP levels typically decline during infancy; however, AFP may be abnormally elevated in blood if certain tumors are present (hepatoblastoma). In some children with BWS, parts of the body, such as the ears, may grow abnormally large, leading to an asymmetric or . Most children with Beckwith-Wiedemann syndrome and isolated hemihypertrophy grow up to be healthy adults. There is no specific increased risk for BWS within specific race/ethnicity populations although the clinical presentations may vary between groups. It is classified as an overgrowth syndrome, which means that affected infants are larger than normal (macrosomia), and some may be taller than their peers during childhood. Macroglossia, omphalocele, adrenal cytomegaly, gigantism, and hyperplastic visceromegaly. Beckwith-Wiedemann; meta-analysis; molecular group and tumor risk; oncological surveillance; tumor screening. However, imprinting refers to the process of deactivating 1 copy of a gene so that only a single copy is expressed normally. Beckwith-Wiedemann Syndrome. 1 Diagnosis may be difficult when a child has only 1 feature of the syndrome (eg, macroglossia) or 1 or more less commonly known features. multiple features that occur variably; most prominent is the EMG triad (exomphalos-macroglossia-gigantism): apart from the abdominal wall defects and pre- and postnatal growth abnormalities, earlobe pits or creases, facial nevus flammeus, hypoglycemia, renal abnormalities and hemihypertrophy (unilateral overgrowth) are frequently seen The probability of cure depends in part upon the extent of the cancers spread (its stage) at diagnosis, as well as its histology or acquired genetic changes in the tumor tissue. Division of Human Genetics What can I do to reduce my childs risk of cancer? Beckwith-Wiedemann syndrome is another instance of increased risk of development of WT and occurs due to loss of function of the WT2 gene on chromosome 11p15. Beckwith-Wiedemann syndrome due to CDKN1C mutation Beckwith-Wiedemann syndrome due to imprinting defect of 11p15 Beckwith-Wiedemann syndrome due to NSD1 mutation Beckwith-Wiedemann syndrome due to paternal uniparental disomy of chromosome 11 Bloom syndrome CBL-related disorder Cernunnos-XLF deficiency Cockayne syndrome Cockayne syndrome type 1 Not every patient with a clinical diagnosis of BWS will have positive confirmatory molecular testing of the syndrome. The phenotypic features of BWS vary greatly from person to person, which can make clinical diagnosis based on physical exam findings and molecular diagnosis based on genetic testing challenging. BWS clinical heterogeneity includes subtle overgrowth features o Characteristic facial abnormalities may include an unusually large head (macrocephaly) that may appear elongated (dolichocephalic) with an abnormally prominent forehead (frontal bossing); widely-spaced eyes (ocular hypertelorism); downwardly slanting eyelid folds (palpebral fissures), a highly-arched roof of the mouth (palate), protrusion of the lower jaw (prognathism); and/or a pointed chin. 40 % of patients with significant lateralized overgrowth ) may occur, resulting in asymmetric growth be.
