For most genes on chromosome 11, both copies of the gene are expressed, or "turned on," in cells. ), 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. 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. 2019 Aug 30. doi: 10.1002/ajmg.c.31740. Due to the mosaic nature of BWS, some patients have eyes with multiple colors. In many infants with umbilical hernia, the defect may spontaneously disappear by the age of approximately one year. Epub 2020 Sep 17. Mussa A, et al. 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. of the Beckwith-Wiedemann spectrum: Diagnosis and management. 2021 Oct;9(10):e1796. Mutations in CDKN1C can also occur randomly without the mother carrying the change (de novo mutation). Low levels of sugar in bloodstream (hypoglycemia) during the newborn period and sometimes prolonged hypoglycemia (due to hyperinsulinism). The syndrome was independently described by J.B . 1 BWS has a wide clinical spectrum. Vuillaume ML, et al. 2005 Jul 1;136(1):95-104. doi: One of the first indications a child may have BWS is fetal macrosomia, an overgrowth syndrome that makes the infant considerably larger at birth. . Before 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. The balance of gene expression from the maternal and the paternal copies are what produce normal, symmetric growth. Children with Beckwith-Wiedemann syndrome are at an increased risk of developing several types of cancerous and noncancerous tumors, particularly a form of kidney cancer called Wilms tumor and a form of liver cancer called hepatoblastoma. Kidney stones have been reported to occur in adolescents and adults with BWS. Smiths Recognizable Patterns of Human Malformation. The Childrens Hospital of Philadelphia.

Normally, every cell has 2 copies of each gene: 1 inherited from the mother and 1 inherited from the father. Oncology: Oncologists can discuss cancer risks, as well as coordinate and review the results of appropriate tests for cancer surveillance. The mutation is inherited as an autosomal dominant trait, which means that only one copy of the mutated gene is needed to pass down the disorder. 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. Epub 2010 Jul 8. 5th ed. Patients with pUPD are also have a greater risk of developing a liver tumor (hepatoblastoma). 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. Normally, people have two copies of chromosome 11, one inherited from their mother and one from their father. Continuous positive airway pressure (CPAP) is a method used to support children with obstructive sleep apnea. Sotos syndrome is an autosomal dominant disorder, meaning only one copy of the mutated gene is necessary for a patient to be affected. This is the area of the chromosome where 2 genes are located: insulin-like growth factor II (IGF-2) and cyclin-dependent kinase inhibitor (CDKN1C). 2013;161A(5): p. 993-1001. Beckwith-Wiedemann Syndrome. 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.

Experts at CHOP recommend that children who have features consistent with a clinical diagnosis of Beckwith-Wiedemann syndrome or isolated hemihypertrophy but who receive negative genetic test results receive the same medical management and cancer surveillance protocol as children who have a confirmed genetic diagnosis. An earlier diagnosis may also reduce the need for chemotherapy and lower the dose of, or eliminate the need for, radiation treatment. INTERNET What are my options for cancer screening? 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. Lateralized overgrowth or isolated lateralized overgrowth (ILO) is a new term used to describe what was previously termed hemihypertrophy or hemihyperplasia.

The physical features of Beckwith-Wiedemann syndrome often become less noticeable as children grow. Conclusion: In about 20% of BWS, a person has inherited both copies of a specific gene from his or her father, leading to some genes having increased expression and others having decreased expression. Diagnosis is then confirmed with chromosomal studies for abnormalities in chromosome 11. Research indicates that omphalocele and macroglossia are more common in individuals with defects of IC2 or a mutation of the CDKN1C gene. FOIA Late-onset complications with BWS may require continued follow-up in adulthood. The .gov means its official. A recent study revealed a tenfold increased risk for BWS in patients conceived via ART, with a prevalence of one in 1,126 patients. have BWS) if the mutation is passed from mother to offspring.

Each year an estimated 11,000 children worldwide are born with BWS. Simpson-Golabi-Behmel syndrome is characterized by overgrowth before and after birth (macrosomia); a particular facial appearance including widely-spaced eyes (hypertelorism), coarse facial features, an abnormally large mouth (macrostomia), an abnormally large head (macrocephaly), an abnormally large tongue (macroglossia), and mild to severe intellectual disability. 2020 Jan 21;7:562. doi: Researchers believe that the paternally-expressed genes promote growth and that the maternally-expressed genes act as tumor suppressor genes or inhibit growth. Beckwith Wiedemann syndrome (BWS) is the most common overgrowth and cancer predisposition disorder caused by the alteration in chromosome 11p15. The diagnosis of Beckwith-Wiedemann syndrome and hemihypertrophy are clinical diagnoses, meaning the diagnosis is made when a child has some or all of the physical features associated with the condition. Powered by NORD, the IAMRARE Registry Platform is driving transformative change in the study of rare disease.
