Abstract excerpt
Beckwith-Wiedemann syndrome (BWS) is an overgrowth malformation syndrome that maps to human chromosome 11p15.5, a region that harbours a number of imprinted genes. We studied the methylation status of H19 and KCNQ1OT1 (LIT1/KvDMR1) in a large series of BWS patients. Different patient groups were identified: group I patients (20%) with uniparental disomy and hence aberrant methylation of H19 and KCNQ1OT1; group II...
