Some cases may be associated with a defect in chromosome number 11. Affected children are often large at birth. Many have an abdominal wall defect, such as an umbilical hernia or omphalocele. They have a characteristic facial appearance with a gaping mouth and large tongue. Infancy can be a critical period because of low blood sugar (hypoglycemia)

Extractions: Beckwith-Wiedemann Syndrome is a very rare condition that is associated with a large body size (macrosomia), large tongue (macroglossia), omphalocele (a type of umbilical hernia), small head (microcephaly), and large body organs (visceromegaly), especially the kidneys and pancreas. Newborns with this condition can also have low blood sugars (hypoglycemia) and high red blood cell counts (polycythemia). Some children will have unusual fissures or creases in their earlobes. Please note that most large babies that have problems with low blood sugar will not have Beckwith-Wiedemann syndrome. The low blood sugar secondary to this syndrome is persistent and difficult to treat.

Beckwith Beckwith Wiedemann Syndrome beckwithwiedemann syndrome (BWS) is a commongenetic overgrowth syndrome that is associated with visceromegaly http://home.coqui.net/myrna/beck.htm
Extractions: Beckwith-Wiedemann syndrome (BWS) is a common genetic overgrowth syndrome that is associated with visceromegaly, macroglossia, abdominal wall defects, pre- and postnatal overgrowth, and neonatal hypoglycemia. Exomphalos, macroglossia, and gigantism, are considered the characteristic diagnostic triad of findings; due to this it is also known as EMG-syndrome. Other distinctive features include earlobe creases and pits, facial nevus flammeus, and prominent eyes with infraorbital creases. Recognition of BWS is important because of the associated risk for development of embryonal neoplasms affecting abdominal organs, the need for prompt treatment of neonatal hypoglycemia, and for purposes of genetic counseling. The primary care physician can provide a major source of support for the family. It is important to emphasize that most infants with BWS grow up to become relatively normal adults. GENETICS AND ETIOLOGY Although most cases appear to be sporadic (85%), the etiology of BWS is generally accepted as genetic. Since the clinical findings vary widely and tend to become less obvious with age, the syndrome may be overlooked in adults, thus tending to mask familial inheritance among some previously reported cases. Present evidence supports autosomal dominant inheritance of BWS, with reduced penetrance and variable expressivity that may relate to the effects of genomic imprinting. (Imprinting is defined as the differential expression of genetic material, at either a chromosomal or an allelic level, depending on whether the genetic material has been inherited from the mother or the father).

Extractions: (advertisement) Synonyms, Key Words, and Related Terms: exomphalos, macroglossia, gigantism syndrome, EMG syndrome, BWS Background: In Germany in 1964, Hans-Rudolf Wiedemann reported a familial form of omphalocele with macroglossia. J Bruce Beckwith at Loma Linda University (Loma Linda, California) described a similar series of patients in 1969. Originally, Professor Wiedemann coined the term EMG syndrome to describe the combination of congenital exomphalos, macroglossia, and gigantism. Over time, this constellation was renamed Beckwith-Wiedemann syndrome (BWS). Pathophysiology: Although the underlying causes of BWS remain unclear, roughly 80% of BWS patients demonstrate genotypic abnormalities of the distal region of chromosome arm 11p. The BWS region of 11p was the first identified example of imprinting in mammals (ie, the process whereby the two alleles of a gene are expressed differentially). Authors most often have used the term imprinted to refer to the expressed allele. For example, the maternal allele of band 11p15.5 normally is expressed, or imprinted. Some authors, however, define the silent allele as imprinted. While reviewing the literature, the reader must bear in mind this inconsistent and confusing nomenclature. Imprinting has been associated with structural modifications of DNA near the gene, such as methylation or lack of acetylation. Several 11p genes are imprinted, including
