Beckwith-Wiedemann syndrome[bek´with ve´dĕ-mahn]
an autosomal dominant syndrome with variable expressivity, usually seen as a growth-related disorder in infants with risk of the development of hypoglycemia and tumors; other characteristics include umbilical hernia, large protruding tongue, and gigantism, often with visceromegaly, adrenocortical cytomegaly, and dysplasia of the renal medulla. Information and peer support for families affected with this disorder can be obtained from the Beckwith-Wiedemann Support Network on the Internet at http://beckwith-wiedemann.org.
Beck·with-Wie·de·mann syn·drome(bek'with vē'dĕ-mahn), [MIM*130650]
an overgrowth syndrome characterized by exomphalos, macroglossia, and gigantism, often with neonatal hypoglycemia; there is an association with hemihypertrophy Wilms tumors and adrenocortical cancer. Autosomal dominant inheritance, with most cases sporadic; influenced by genomic imprinting and uniparental disomy; caused by change in the P57 (KIP2) gene locus on chromosome 11p.
CDKN1CA gene on chromosome 11p15.5 that encodes a strong inhibitor of several G1 cyclin/Cdk complexes and a negative regulator of cell proliferation.
CDKN1C mutation is implicated in sporadic cancers and Beckwith-Wiedemann syndrome, suggesting a role in tumour suppression.
