A previously unreported family in which seven members in two generations have Beckwith-Wiedemann syndrome (BWS) is documented. Paternal imprinting of the gene responsible for BWS is involved as the mechanism responsible for the aberrant inheritance pattern in this kindred. A review of published reports showed 27 previously published pedigrees with two or more affected subjects with BWS. Paterna...

In this study, we have examined CDKN1C expression in BWS patients with allele imbalance (AI) affecting the 11p15 region. Two of two informative patients with AI, attributable to mosaic paternal isodisomy, exhibited reduced levels of CDKN1C expression in the liver and kidney, respectively, relative to expression levels in the equivalent tissues in normal controls. Although overall expression was...

Beckwith-Wiedemann syndrome (BWS) is a model imprinting disorder resulting from mutations or epimutations affecting imprinted genes on chromosome 11p15.5. The classical clinical features of BWS are macroglossia, preand/or postnatal overgrowth, and anterior abdominal wall defects (umbilical hernia or exomphalos). Additional more variable features include hemihypertrophy, neonatal hypoglycaemia, ...

Cystic fibrosis (CF) is a hereditary disease of exocrine gland function that involves multiple systems but chiefly results in chronic respiratory infections, the major cause of death, pancreatic enzyme deficiency and severe malnutrition, mostly in untreated patients. The association between CF and other inherited diseases or congenital anomalies is rare. We describe for the first time the assoc...

Beckwith Wiedemann Syndrome (BWS) is a rare congenital disease of low prevalence. However, it presents a high prevalence within the genetic pathologies of overgrowth. This syndrome presents typical manifestations such as macroglossia, macrosomy at birth, omphalocele and defects of the anterior abdominal wall. Its origin is known to be genetic, but its mechanism of generation is not clear. This ...

Beckwith-Wiedemann syndrome (BWS) is a clinically heterogeneous overgrowth syndrome associated with an increased risk for embryonal tumour development. Russell-Silver syndrome (RSS) is a genetically heterogeneous disorder involving both intrauterine and postnatal growth retardation. The incidence of both BWS and RSS is estimated to be approximately 1 in 10,000-15,000 newborns and around 85% of ...
