EMG Syndrome Exomphalos Macroglossia Gigantism Syndrome Wiedemann Beckwith; WBS … The cardinal features of this disorder, which is most often referred to as Beckwith Wiedemann syndrome (BWS), are exomphalos, macroglossia, and gigantism in the neonate. This was the origin of the initialism EMG syndrome … BWS patients are at increased risk of developing specific tumors … Caused by mutation in the chromosome 11p15.5 region. Duplication in this region appears to be involved in the pathogenesis and imprinting results in anomalous patterns of transmission. Most cases are sporadic … The enlarged tongue, together with omphalocele or other umbilical abnormalities, permits recognition of the disorder at birth … Many of the affected infants have hypoglycemia in the first days of life, anticipation of this complication can prevent serious neurologic sequelae … 'Typical linear indentations of the lobe' that have become one of the diagnostic criteria … Of 388 children, 29 developed 32 neoplasms … 14 being Wilms tumors and 5 adrenocortical carcinoma. Hemihypertrophy, partial or complete, was noted in 12.5% of the cases but in more than 49% of the children with neoplasms … Wiedemann (1989) commented on overgrowth of the external genitalia in both males and females … Average height of 2.5 SD above the mean at or after puberty … Bone age was significantly advanced in all patients studied … Pregnancies in these cases tended to have polyhydramnios with large placentas that were almost twice the normal placental weight … Large fetal size and polyhydramnios often resulted in early delivery with occasional perinatal mortality. Excessive umbilical cord length was a manifestation of the increased placental size and was a useful sign in suspecting WBS before delivery … The mode of inheritance is complex. Possible patterns include autosomal dominant inheritance with variable expressivity, contiguous gene duplication at 11pl5, and genomic imprinting resulting from a defective or absent copy of the maternally derived gene … That fetal hyperinsulinism may be involved in the latter condition, inasmuch as the insulin gene (INS; 176730) is located in the 11p15 region ...

Concerned with prenatal aspects. Nicely illustrated … Untreated neonatal hypoglycemia is an important complication and may result in further cerebral dysfunction, such as seizures, mild to moderate mental retardation, or neonatal death in more severe cases. Macroglosia can cause variable complications ranging from feeding difficulties to airway obstruction and death … Neonatal mortality rate is approximately 21% ...
