Description : Beckwith-Wiedemann syndrome is a pediatric overgrowth disorder involving a predisposition to tumor development. The clinical presentation is highly variable; some cases lack the hallmark features of exomphalos, macroglossia, and gigantism as originally described by Beckwith (1969) and Wiedemann (1969) (summary by Weksberg et al., 2010).;

Inheritance : Autosomal dominant;

Molecular basis : Caused by contiguous gene duplication of imprinted region of 11p15.5; Caused by mutation in the nuclear receptor binding SET domain protein 1 (NSD1, 606681.0011); Caused by mutation in the cyclin-dependent kinase inhibitor 1C gene (CDKN1C, 600856.0001); Caused by contiguous gene deletion of imprinted region of 11p15.5; Caused by mutation in the KCNQ1-overlapping transcript 1 gene (KCNQ1OT1, 604115.0001);

Neoplasia : Wilms tumor; Hepatoblastoma; Adrenal carcinoma; Gonadoblastoma;

Laboratory abnormalities : Duplication or deletion at 11p15.5;

Prefixed ID : #130650;
