Some infants with Beckwith-Wiedemann syndrome have an abnormally large tongue (macroglossia), which may interfere with breathing, swallowing, and speaking. The syndrome was independently described by J.B. Beckwith, an American pathologist, at the annual meeting of the Western Society for Pediatric Research in 1963 [ 1 ] and H.R. Additionally, in some affected patients, there may be improper contact of the teeth of the upper and lower jaws (malocclusion) and abnormal protrusion of the lower jaw (mandibular prognathism), features that may occur secondary to macroglossia.

NORD and MedicAlert Foundation have teamed up on a new program to provide protection to rare disease patients in emergency situations. 2022 The Childrens Hospital of Philadelphia. Oxford University Press, New York, NY; 2019:39-63. Mosaic paternal UPD leads to an imbalance in active paternal and maternal genes on chromosome 11, which underlies the signs and symptoms of the disorder. (For more information on this disorder, choose Weaver as your search term in the Rare Disease Database.). Description An inherited condition that affects how different parts of the body grow. About 10 percent of people with Beckwith-Wiedemann syndrome develop tumors, typically in childhood. About 14% of patients with BWS have an unknown cause for diagnosis. Possible causes for Beckwith-Wiedemann syndrome are: While some cases are inherited from a parent, most cases occur as new genetic abnormalities only within the affected child. 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. However, because children who have milder cases of the syndrome may never receive a diagnosis of Beckwith-Wiedemann syndrome or 11p overgrowth spectrum, this figure may be an underestimation. However, CDKN1C is normally only maternally expressed, and therefore, the offspring will only be affected (i.e. European Journal of Human Genetics 2019; 27(4):663-668. Diagnosis is then confirmed with chromosomal studies for abnormalities in chromosome 11. Defining an optimal time window to screen for hepatoblastoma in children with Beckwith-Wiedemann syndrome. 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). About 14% of patients with BWS have an unknown cause for diagnosis. BWS results from various abnormalities affecting the proper expression of genes that control growth within a specific region of chromosome 11(11p15.5). Neri G, Boccuto L, Stevenson RE. Eur J Hum Genet. Also, screening for patients with BWS due to GWpUPD may extend beyond the 7th birthday. Signs and symptoms of BWS can range from mild to severe. The trend in AFP levels over time should be followed in patients with BWS and normal AFP values for children with BWS are available to aid in interpretation of results. AFP levels typically decline during infancy; however, AFP may be abnormally elevated in blood if certain tumors are present (hepatoblastoma). Cohen JL, et al.

Beckwith-Wiedemann syndrome (BWS) is a human genomic imprinting disorder that presents with a wide spectrum of clinical features including overgrowth, abdominal wall defects, macroglossia, neonatal hypoglycemia, and predisposition to embryonal tumors. Int J Dev Biol, 2014; 58: 291298. J Med Genet. uniparental disomy in Beckwith-Wiedemann syndrome. In about 10% to 15 % of cases, the genetic changes may be inherited. A blood test to measure serum AFP should be performed every three months until 4 years of age. Epub 2017 Mar 29. Comparisons may be useful for a differential diagnosis: Simpson-Golabi-Behmel syndrome is an X-linked recessive genetic disorder due to mutations in the GPC3 or GPC4 genes. Aug 30. The genetic testing methods that are currently available may be able to identify up to 80% of genetic mutations causing BWS. This risk depends on the genetic cause of the condition. There is no specific increased risk for BWS within specific race/ethnicity populations although the clinical presentations may vary between groups. Epub 2015 Apr 22.

Other treatment is symptomatic and supportive. Current suggested screenings for people who are known or suspected to have BWS include: Baseline magnetic resonance imaging (MRI) or computed tomography (CT or CAT) scan of the abdomen at the time of diagnosis, Abdominal ultrasound to screen for hepatoblastoma and Wilms tumor every 3 months, until age 4. The information on this site should not be used as a substitute for professional medical care or advice. T, Baker R, Bertoletti M, Cocchi G, Coze C, De Pellegrin M, Hussain K, Ibrahim A, 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. It is recommended that all families considering genetic testing for BWS meet with a clinical geneticist, a medical doctor who has training in genetics, and a genetic counselor that can explain the tests and coordinate testing. Front Pediatr. Epub 2016 Mar 15. Weaver syndrome is characterized by accelerated growth. Tumor risk in Beckwith-Wiedemann syndrome: A 1994 Oct;31(10):749-53. doi: 10.1136/jmg.31.10.749. If we dont have a program for you now, please continue to check back with us. About twenty percent of cases of Beckwith-Wiedemann syndrome are caused by a genetic change known as paternal uniparental disomy (UPD). Support may be needed to assist with feeding difficulties in infancy and speech development in childhood. The severity of this disorder varies widely in children and is usually recognized at birth, when a child is born with several features of Beckwith-Wiedemann syndrome. of the Beckwith-Wiedemann spectrum: Diagnosis and management. 2020 Jan 21;7:562. doi: Beckwith-Weidemann syndrome (BWS) is a genetic or congenital condition present from birth and causes physical differences in the child's body compared to other children at birth. CHOP recommends the following cancer screening protocol for patients suspected of having, or proven to have, Beckwith-Wiedemann syndrome or isolated hemihypertrophy: Abdominal ultrasound Med Pediatr Oncol. A cancer screening. Nomenclature and definition in asymmetric regional body overgrowth. 1900 Crown Colony Drive By adolescence, growth tends to normalize and cancer risk decreases. Symptoms of the following disorders can be similar to those of BWS. New York, NY Oxford . Patients with pUPD are also have a greater risk of developing a liver tumor (hepatoblastoma). It is a rare disorder, also referred to as overgrowth syndrome, and may involve several body parts. consensus document: Clinical and molecular diagnosis, screening and management of Tumors develop in about 10 percent of people with this condition and almost always appear in childhood. Bookshelf Beckwith-Wiedemann spectrum is a genetic disorder that can cause overgrowth of body parts (hypertrophy) along with other medical findings (described below). Domain. This is an extremely sensitive way to detect these cancers. Beckwith-Wiedemann syndrome is a condition that affects many parts of the body. http://www.ncbi.nlm.nih.gov/books/NBK1394/. Clinical and molecular characterization of patients affected by Beckwith-Wiedemann spectrum conceived through assisted reproduction techniques. The 10% to 15% of BWS that is inherited follows an autosomal dominant inheritance pattern. Diagnosis and management of the phenotypic spectrum of twins with Beckwith-Wiedemann syndrome. Seattle (WA): University of Washington, Seattle; 1993-2019. Loss of methylation (hypomethylation) at KvDMR of imprinting center 2 (IC2 LOM) occurs in about 50% of people with BWS. It is estimated to occur in 1 in 10,340 individuals in the general population. Beckwith-Wiedemann syndrome (BWS), recently reclassified as Beckwith-Wiedemann spectrum , is a congenital overgrowth disorder characterized by a unique set of features that can consist of: macroglossia : most common clinical finding 4 ear pits or creases omphalocele localized gigantism / macrosomia lateralized overgrowth (hemihypertrophy) Methylation is a chemical reaction that attaches small molecules called methyl groups to certain segments of DNA. A total of four or more points, two of which should be due to a cardinal feature, is consistent with a clinical diagnosis of BWS. Because hemihypertrophy can present either as an isolated condition, or as a feature of Beckwith-Wiedemann syndrome, all children with hemihypertrophy should seek an evaluation from a geneticist to establish a correct diagnosis. Am J Med Genet Last updated: Patients must rely on the personal and individualized medical advice of their qualified health care professionals before seeking any information related to their particular diagnosis, cure or treatment of a condition or disorder. Some patients may undergo tongue reduction surgery with the goal of improving breathing, feeding, and jaw or dental malformations due to macroglossia. As such, cardinal features are given two points each in the scoring system. Accessibility European Journal of Medical Genetics. Thirty-eight patients were investigated to determine clinical and/or biological signs associated with a tumor presence.
