Beckwith-Wiedemann syndrome (BWS; MIM #130650) is a pediatric overgrowth disorder involving a predisposition to tumor development [ 1 ]. [updated 2016 Aug 11]. Philadelphia, PA 19104, Know My Rights About Surprise Medical Bills, Beckwith-Wiedemann Syndrome Coloring Book, Beckwith-Wiedemann Childrens Foundation International, Beckwith-Wiedemann syndrome support group, Genetics Home Reference Beckwith-Wiedemann syndrome, Medline Plus Beckwith-Wiedemann syndrome, National Cancer Institute Wilms' Tumor and Other Childhood Kidney Tumors, Large birth weight and length (macrosomia), Overgrowth of one side or one part of the body (hemihypertrophy/hemihyperplasia)). Epub 2013 Dec 4. Less severe abdominal defects can include protrusion of part of the intestines through an abnormal opening in the muscular wall of the abdomen near the umbilical cord (umbilical hernia), or weakness and separation of the left and right muscles of the abdominal wall (diastasis recti). European Journal of Medical Genetics. Peutz Jeghers syndrome: A disorder in which polyps develop in the intestine and increases the risk of developing cancer. However, some genes are turned off or preferentially silenced based upon which parent that gene came from (a process known as genomic imprinting). About 14% of patients with BWS have an unknown cause for diagnosis. It is a rare disorder, also referred to as overgrowth syndrome, and may involve several body parts. Beckwith-Wiedemann Syndrome (BWS) is a genetic disorder that affects your child's growth and increases their risk of developing certain childhood cancers. Broader symptoms and physical findings have been represented, showing variations as per the disease severity in different children. The genetic causes of Beckwith-Wiedemann syndrome are complex. TTY: (866) 411-1010 Genetic Testing Registry: Beckwith-Wiedemann syndrome, National Organization for Rare Disorders (NORD). Patients with macroglossia are at an increased risk for obstructive sleep apnea, feeding difficulties, speech difficulties, and potential jaw development issues. Unable to load your collection due to an error, Unable to load your delegates due to an error. Most children with Beckwith-Wiedemann syndrome and isolated hemihypertrophy grow up to be healthy adults. In newborns with BWS, regular monitoring of blood glucose levels should be performed to ensure prompt detection and treatment of hypoglycemia. The most common prenatally detected feature that leads to a higher clinical suspicion of BWS is an omphalocele. In these cases, there is up to a 50 percent chance that an affected or carrier parent will pass on the genetic abnormality to a child during pregnancy. Nomenclature and definition in asymmetric regional body overgrowth. A polysomnography (sleep study) may be used to assess for obstructive sleep apnea, airway obstruction, airway resistance, severe desaturation, sleep disordered breathing, and snoring. A variety of kidney (renal) abnormalities can occur in individuals with BWS, including abnormally large kidneys (nephromegaly), improper development of the innermost tissues of the kidney (renal medullary dysplasia), and the formation of calcium deposits in the kidney (nephrocalcinosis), which could potentially impair kidney function. Entry . Also, screening for patients with BWS due to GWpUPD may extend beyond the 7th birthday. This is termed mosaicism. For this reason, testing multiple tissues can increase the likelihood of finding the cause of BWS. More research is needed to understand the features and associated treatments for adults with BWS. Beckwith JB. It allows people who carry a specific known genetic mutation to reduce the likelihood that their children will inherit the condition. A normal genetic test result does not rule out the diagnosis of these disorders. Patients with CDKN1C mutations may deserve neuroblastoma screening based on urinary markers and ultrasonography scanning. Analysis methods PLUS Availability 4 weeks The maternal copy of chromosome 11 will express some genes that control growth on chromosome region 11p15 that the paternal copy does not, and vice versa. The Infona portal uses cookies, i.e. However, parents of one child with Beckwith-Wiedemann syndrome may be at risk of having other children with the disorder. Tumor risk in Beckwith-Wiedemann syndrome: A Cancer ORs were 12.8 in ICR1-GoM, 6.5 in UPD, and 2.9 in patients with CDKN1C mutations compared with patients with ICR2-LoM. Some may have only a single, subtle feature, such as isolated hemihypertrophy of a limb (also known as hemihyperplasia). Less than 1 percent of Beckwith-Wiedemann syndrome cases are due to a different type of abnormality on the same chromosome, a rearrangement of genetic material known as a "translocation" or an "inversion." Available from Usually, this results in both copies of the genes being expressed. 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. However, CDKN1C is normally only maternally expressed, and therefore, the offspring will only be affected (i.e. However, without proper detection and appropriate treatment, neurological complications may result. Last update: December 2011. J Pediatr. Alpha-fetoprotein (AFP) is a protein produced by the liver. Over half of infants with BWS are above the 97th percentile in weight for gestational age. 10.1002/(sici)1096-911x(199706)28:6<411::aid-mpo3>3.0.co;2-j. They generally grow up to be adults of above average height. Epub 2013 Apr 16. Cooper WN, Curley R, Macdonald F, Maher ER. Additionally, if previous testing is normal, CDKN1C sequencing is performed to detect any changes in the CDKN1C gene. In addition to macroglossia, BWS may be characterized by other abnormalities of the skull and facial (craniofacial) region. J Mol Diagn. Beckwith-Wiedemann syndrome. Richard Wills. Some infants may have flat, pale red or reddish purple facial marks at birth, most commonly on the eyelids and forehead, which consist of abnormal clusters of small blood vessels (facial nevus simplex). Please enable it to take advantage of the complete set of features! A patient who presents with physically apparent features and who appears more affected is thought to present with classic or typical BWS. Prawitt D, Riccio A, Temple IK, Weksberg R. Clinical utility gene card for: PGD has been in use for over 2 decades, and has been used for several hereditary cancer predisposition syndromes. 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). 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. Am J Med Genet A. Beckwith-Wiedemann Syndrome. BWS clinical heterogeneity includes subtle overgrowth features o Patients with BWS may have an increased risk of developing certain childhood cancers. For other genes, only the copy inherited from a person's mother (the maternally inherited copy) is expressed. Not surprisingly, the full story of BWS was too big to be fully contained in a recent article in Bench to Bedside, the monthly newsletter of The Children's Hospital of Philadelphia Research Institute. Abdominal wall defects can include an omphalocele (also known as exomphalos), in which part of an infants intestines and abdominal organs are outside of the body because of an opening in the belly button. Genetic testing for gene mutations associated with BWS is available, but it is complex. The https:// ensures that you are connecting to the In about 85 percent of cases of Beckwith-Wiedemann syndrome, only one person in a family has been diagnosed with the condition. 8600 Rockville Pike 2015; 4(3): 135-143. Because people who are mildly affected may go undiagnosed, it is difficult to determine the true frequency of BWS in the general population. Case Report of Congenital Hepatoblastoma With the Onset at 30-Weeks' Gestation. Beckwith-Wiedemann syndrome (BWS) is a rare disorder present at birth that causes overgrowth in children. Insulin helps regulate blood glucose levels by promoting the movement of glucose into cells. Not every patient with a clinical diagnosis of BWS will have positive confirmatory molecular testing of the syndrome. The SAGE Encyclopedia of Cancer and Society. ), or their login data. Updates to this page are in process. Beckwith-Wiedemann syndrome is often associated with changes in regions of DNA on chromosome 11 called imprinting centers (ICs). Several types of childhood tumors, including Wilms tumor (), adrenocortical carcinoma (), and rhabdomyosarcoma (), display a specific loss of maternal 11p15 . 2019 Dec;181(4):693-708. doi: 10.1002/ajmg.c.31740. Features that are seen in BWS but are also present in the general population are termed suggestive features (including large birth weight, macrosomia, facial nevus simplex, polyhydramnios or placentamegaly, ear creases or pits, hypoglycemia, embryonal tumor such as single Wilms tumors or hepatoblastomas, nephromegaly or hepatomegaly, umbilical hernia, and diastasis recti). 2016 Jul;90(1):21-7. doi: 10.1111/cge.12759. Approximately 1 in 13,700 people have BWS. Chromosome 11p15.5 has two imprinting cluster regions known as imprinting centers 1 and 2 (IC1 and IC2). FOIA Several genes that control growth on chromosome 11 are imprinted, which means that the gene is only active from the mothers chromosome or the fathers chromosome but not both. Jones KL, Jones M, Del Campo M. Eds. Disease Ontology: 11 A syndrome characterized by overgrowth (macrosomia), an increased risk of childhood cancer and congenital malformations. MeSH Patients with pUPD are at a greater risk for lateralized overgrowth and hyperinsulinism. Some children with Beckwith-Wiedemann syndrome and isolated hemihypertrophy may need to see other medical specialists. Thirty-eight patients were investigated to determine clinical and/or biological signs associated with a tumor presence. Vanderver A, Pearl PL. doi: 10.1002/(sici)1096-911x(199706)28:6<411::aid-mpo3>3.0.co;2-j. This syndrome is characterized by macroglossia, omphalocele, organomegaly, genitourinary anomalies, and increased risk of abdominal tumors. Phone: 617-249-7300, Danbury, CT office This means that the risk for BWS can be passed from generation to generation in a family. Cancer Screening tools that are epigenetically based have shown promise in diagnosing which types of cancer? Epub 2019 Phone: 203-263-9938 Other treatment is symptomatic and supportive. Reviewed June 2015. UPD also was associated with hepatoblastoma (OR 5.2) and adrenal carcinoma (OR 7.0), and CDKN1C mutations with neuroblastic tumors (OR 7.2). Bean LJH, Gripp KW, Amemiya A, editors. An official website of the United States government. NORD strives to open new assistance programs as funding allows. This leaves only the paternally expressed IGF2 to promote cell proliferation. Duffy KA, et al. Patients with cardiac, gastrointestinal, and renal abnormalities may require certain medications, surgery, or other medical interventions. Beckwith-Wiedemann syndrome is associated with an increased risk of cancer, including Wilms tumour , rhabdomyosarcoma , neuroblastoma and Mussa A, et al. Growth begins to slow by about age 8, and adults with this condition are not unusually tall. Beckwith-Wiedemann syndrome: Clinical, histopathological and molecular study of two Tunisian patients and review of literature. Such marks typically become less apparent during the first year of life. The cancer risk is highest in children with BWS who have hemihyperplasia and organomegaly, meaning the enlargement of organs, especially nephromegaly, the enlargement of the kidneys, than in children with isolated hemihypertrophy. 10.1002/ajmg.a.30729. This region is referred to as the BWS critical region. In Beckwith-Wiedemann syndrome, paternal UPD usually occurs early in embryonic development and affects only some of the body's cells. BWS is a recognized cancer predisposition syndrome, with an estimated tumor risk of 8 to 10% in the first decade of life, with the highest incidence during the first 2 years of life. Genomic imprinting is controlled by marks on the DNA called methylation. Before The .gov means its official. The syndrome was independently described by J.B . Tumors develop in about 10 percent of people with this condition and almost always appear in childhood. www.centerwatch.com, For more information about clinical trials conducted in Europe, contact: Affected infants and patients may also demonstrate developmental abnormalities including delays in reaching developmental milestones (e.g., sitting, crawling, and walking), delays in coordination of muscular and mental activity (psychomotor retardation), and delays in language skills. American Journal of Medical Genetics. ILO is defined as asymmetric overgrowth of the body. This first-of-its-kind assistance program is designed for caregivers of a child or adult diagnosed with a rare disorder. Pediatric Blood & Cancer 2018; 65(10): e27296. 2022 Jul 1;10:905089. doi: 10.3389/fped.2022.905089. Approximately 80% of people with BWS have no family history of this syndrome. One of the first indications a child may have BWS is fetal macrosomia, an overgrowth syndrome that makes the infant considerably larger at birth. who subsequently developed breast cancer and then lung cancer. La sndrome de Beckwith Wiedemann (BWS) s un trastorn congnit de creixement excessiu caracteritzat per un risc elevat de cncer infantil i An official website of the United States government. Beckwith-Wiedemann Syndrome. Thirty-eight patients were investigated to determine clinical and/or biological signs associated with a tumor presence. Children with BWS may also have hemihyperplasia, in which some parts of the body are larger on one side than on the other. People with paternal UPD are also missing genes that are active only on the maternally inherited copy of the chromosome. 2022 The Childrens Hospital of Philadelphia. AFP is a protein released by immature or damaged liver cells, and it is released at higher levels by hepatoblastoma tumor cells. 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. Late-onset complications with BWS may require continued follow-up in adulthood. The overgrowth may be limited to one body area, such as the legs, head or tongue, or it may involve several different areas of the body. 2005; 13:102532. Wilms tumor was associated with ICR1-GoM (OR 68.3) and UPD (OR 13.2). BWS has been found across different population groups. Autosomal dominant inheritance means that one copy of an altered gene in each cell is typically sufficient to cause the disorder. A person who inherits the altered gene may not have any of the characteristic signs and symptoms of the condition, depending on which parent passed the altered copy to them. This gene provides instructions for making a protein that helps control growth before birth. 7th ed. Finally, screening appears questionable in cases of ICR2-LoM, given low tumor risk. He had many of the characteristic symptoms: large birth weight, an enlarged tongue, hypoglycemia, omphalocele and hernia, as well a likely unrelated heart condition, pulmonary stenosis. Epigenetic change has been considered a developmental landscape that can channel specific differentiation events and define and constrain distinct phenotypic and gene expression states. Some infants with Beckwith-Wiedemann syndrome have an abnormally large tongue (macroglossia), which may interfere with breathing, swallowing, and speaking. MedlinePlus links to health information from the National Institutes of Health and other federal government agencies. Am J Med Genet C Semin Med Genet. A total of two or more points indicates the need for molecular testing, especially if a cardinal feature is present. Suite 500 government site. Usually diagnoased <4 yo around 22 months on average. The most common features of BWS include macrosomia (large body size), macroglossia (large tongue), abdominal wall defects, an increased risk for childhood tumors, kidney abnormalities, hypoglycemia (low blood sugar) in the newborn period, and unusual ear creases or pits. In some cases, certain procedures may be performed before birth (prenatally) to detect BWS. It is generally agreed that at least 1 major feature and 2 minor features are required for a diagnosis of BWS: Omphalocele (abdomen protrudes through navel), Hemihyperplasia, meaning some parts of the body are larger on 1 side, Visceromegaly, which is the enlargement of 1 or more abdominal organ, Embryonal tumor (Wilms tumor, hepatoblastoma, neuroblastoma, rhabdomyosarcoma), Adrenocortical tumor (adrenal gland tumor), Cleft palate, which is a gap in the roof of the mouth, Polyhydramnios (excessive amniotic fluid), Diastatsis recti, which is the separation of the right and left sides of the main abdominal muscle, Hemangioma, a noncancerous tumor made up of blood vessels, Facial nevus flammeus, a hemangioma of the skin, also called a port-wine stain. Oxford University Press, New York, NY; 2002:11-31. There can be differences in this expression as well from person to person, including both copies being expressed or neither copy is expressed. Lennerz JK, Timmerman RJ, Grange DK, DeBaun MR, Feinberg AP, Zehnbauer BA. Normally, every cell has 2 copies of each gene: 1 inherited from the mother and 1 inherited from the father. J Hum Genet. Wiedemann HR. Additionally, the internal organs of affected individuals can become abnormally enlarged (organomegaly). and transmitted securely. 2019;15: 375-381. Most of the tumors associated with BWS occur in the first 8-10 years of life, and the most common is Wilms tumor (WT). American Journal of Medical Genetics Part A. . What are the different ways a genetic condition can be inherited? For these people, BWS is usually caused by epigenetic changes that appear to occur randomly (sporadically). Until 4 years of age, the ultrasound should include views of the liver, kidneys and other internal organs. NORD is a registered 501(c)(3) charity organization. In about 85% of cases, the genetic changes that cause BWS happen sporadically, meaning it occurs by chance, in families where there is no history of the condition. Kalish JM, et al. Affected individuals may not have all of the symptoms listed. The key with AFP levels is to follow the trend normal levels are expected to decrease over time. ), Weaver syndrome, also known as Weaver-Smith syndrome, is an extremely rare disorder autosomal dominant disorder due to mutations in the EZH2 gene located on chromosome 7q36.1. 2019 Aug 30. doi: 10.1002/ajmg.c.31740. Mussa A, et al. Feeding difficulties caused by macroglossia may require the support of feeding specialists or dieticians. Children with significant hemihyperplasia may need to be evaluated by an orthopedist (bone doctor). Colorectal Cancer 2nd only to lung cancer risk is 2 to 3 times higher than general population in those with 1 affected 1st degree relative The genetic testing methods that are currently available may be able to identify up to 80% of genetic mutations causing BWS. Several different tumor types, both cancerous and benign (noncancerous), have been reported in children with BWS. Consider asking your health care team the following questions: What is my childs risk of developingcancer? A BWS consensus scoring system has been established to help with the clinical diagnosis of BWS and to determine the need for molecular testing. Wang KH, Kupa J, Duffy KA, Kalish JM. Unable to load your collection due to an error, Unable to load your delegates due to an error. Rarely invades the kidney. Eur J Hum Genet. Whenever possible, AFP screening should be done at the same center for consistency of results. Clinical and molecular characterization of patients affected by Beckwith-Wiedemann spectrum conceived through assisted reproduction techniques. Treatment may require the coordinated efforts of a team of specialists. Human Malformations and Related Anomalies 3rd Edition. Geneticists, pediatricians, plastic surgeons, endocrinologists, nephrologists (kidney specialists), orthodontists (dental specialists), pulmonologists (lung specialists), speech pathologists, pediatric oncologists, and other healthcare professionals may need to systematically and comprehensively plan an affected childs treatment. Ensuring that patients and caregivers are armed with the tools they need to live their best lives while managing their rare condition is a vital part of NORDs mission. Phone: 202-588-5700. Cancer screening in BWS could be differentiated on the basis of (epi)genotype and target specific histotypes. Am J Med Genet A. Sequence similarities. Some researchers believe this number could be an underestimate. (Epi)genotype-phenotype correlations in Beckwith-Wiedemann syndrome. Most common (adrenal) solid tumor cancer in infants. Uniparental paternal disomy occurs after fertilization (post-zygotic), and therefore the risk of recurrence is extremely low. Most hereditary cases are associated with a mutation in a gene on chromosome 11 known as CDKN1C. May;89(5):613-7. doi: 10.1016/j.ygeno.2007.01.005. There have been recent discussions regarding the utility of AFP screening in young children. The ultimate goal of IAMRARE is to unite patients and research communities in the improvement of care and drug development. Breast c. Skin d. Rump P, Zeegers MP, van Essen AJ. A Beckwith-Wiedemann Registry was established to coordinate research efforts into Beckwith-Wiedemann syndrome. Cohen MM Jr, Nori G, Weksberg R. Overgrowth Syndromes. Epub 2010 Oct 22. Imprinted genes tend to be clustered or grouped together. It's important to be diagnosed early since children born with the condition are more likely to develop tumors that could be cancerous. J Med Genet. In the event that screening results in a suspected or confirmed tumor, we recommend a prompt referral to a pediatric oncologist. Variants in the CDKN1C gene prevent this protein from restraining growth, which leads to the abnormalities characteristic of Beckwith-Wiedemann syndrome. Orphanet: 58 Beckwith-Wiedemann syndrome (BWS) is a genetic disorder characterized by overgrowth, tumor predisposition and congenital malformations. Some of the visible, physical signs of Beckwith-Wiedemann syndrome, such as a disparity in leg length or an enlarged tongue, may require surgical correction, but most of the characteristics become less apparent with time. Sassi H, Elaribi Y, Jilani H, Rejeb I, Hizem S, Sebai M, Kasdallah N, Bouthour H, Hannachi S, Beygo J, Saad A, Buiting K, H'mida Ben-Brahim D, BenJemaa L. Mol Genet Genomic Med. Proper genomic imprinting is necessary for normal development and defective imprinting on chromosome 11 can lead to BWS. Loss of methylation (hypomethylation) at KvDMR of imprinting center 2 (IC2 LOM) occurs in about 50% of people with BWS. PMC 1900 Crown Colony Drive 2015. Assisted Reproductive Techniques and Risk of Beckwith-Wiedemann Syndrome. It is estimated to occur in 1 in 10,340 individuals in the general population. Treatment measures may include the administration of intravenous glucose, frequent feedings, certain medications (e.g., diazoxide or octreotide), and/or surgical intervention in some cases. Some individuals may appear mildly affected while others appear more significantly affected. There are many other features that may be seen in some children with BWS. Beckwith-Wiedemann syndrome (BWS) (OMIM 130650) is a disease of prenatal overgrowth, congenital malformations, and predisposition to cancer. sharing sensitive information, make sure youre on a federal This phenomenon is called mosaicism. A total of 1370 patients with BWS were included: 102 developed neoplasms (7.4%). GWpUPD is associated with a greater tumor risk. According to the United States-based guidelines, screening is recommended for all patients with a clinical or molecular diagnosis of BWS by AFP analysis and a full abdominal ultrasound every three months until the 4th birthday (to screen for hepatoblastoma and Wilms tumor) followed by renal ultrasounds every 3 months until 7th birthday (to screen for Wilms tumor). Patients with BWS may have an enlarged tongue (macroglossia), which can cause difficulties in speaking, feeding, and breathing. A patient with fewer isolated features, such as neonatal hyperinsulinism or an embryonal tumor, is thought to present with atypical BWS. Genetic testing also may help to determine whether, and how, these disorders occur within a family, which would provide information about the chance for recurrence in other children. Associated features include above-average birth weight (large for gestational age), increased growth after birth (macrosomia), a large tongue (macroglossia), enlargement of certain internal organs (organomegaly), and abdominal wall defects (omphalocele, umbilical hernia, or diastasis recti).
