Clinical and Molecular Characterization of 46 Patients With Beckwith–Wiedemann Spectrum and Uniparental Disomy of 11p15

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Beckwith–Wiedemann spectrum (BWSp) is an overgrowth disorder characterized by its main clinical features macrosomia, macroglossia, and abdominal wall defects. BWSp is caused by (epi)genetic chromosome 11p15 alterations with approximately 20%–27% of patients exhibiting mosaic paternal uniparental disomy of chromosome 11p15 (pUPD11p15).
